SUMMARY

Cybercrime and the Law: Primer on the
Computer Fraud and Abuse Act and Related
Statutes

R47557
May 16, 2023
Peter G. Berris
Legislative Attorney

There is no single, straightforward definition of cybercrime under federal law. Rather, depending
on the context, “cybercrime” may refer to all crimes involving computers, or only to crimes
targeting computers, or to crimes unique to the computer context. Regardless, federal prosecutors
have a number of statutory tools to charge conduct that fits within these varying conceptualizations of cybercrime.
One example of a federal cybercrime provision is the Computer Fraud and Abuse Act (CFAA), 18 U.S.C. § 1030—a law
prohibiting a variety of computer-related conduct and providing for both civil and criminal penalties. Although sometimes
described as an anti-hacking law, the CFAA covers more than just hacking. The statute prohibits seven categories of conduct
involving unauthorized access to computers, including, with certain exceptions and conditions:

•
•
•
•
•

Obtaining national security information through unauthorized computer access and sharing or retaining it;

•
•

Trafficking in passwords or other means of unauthorized access to a computer;

Obtaining certain types of information through unauthorized computer access;
Accessing government computers without authorization;
Engaging in computer-based frauds through unauthorized computer access;
Knowingly causing damage to certain computers by transmission of a program, information, code, or
command;

Making extortionate threats to harm a computer or based on information obtained through unauthorized
access to a computer.
In addition to hacking, some types of cybercrime may include data theft, swatting, doxing, cyberstalking, cyber harassment,
unlawful access to electronic communications, or fraud. To the extent that conduct in these categories involves unauthorized
computer access, the CFAA may provide a powerful statutory tool to prosecute. Depending on the circumstances, prosecutors
may also look to a number of other statutes in their charging decisions. For example, data theft targeting trade secrets may
violate the Economic Espionage Act. Cyber harassment and cyberstalking might run afoul of the federal cyberstalking statute
(18 U.S.C. § 2261A(2)). Swatting—that is, reporting a false emergency in an attempt to direct an armed police response to a
target or location—may violate a federal law proscribing the transmission of certain threats in interstate commerce. When it
targets certain federal officials, doxing—obtaining another individual’s personal identifying information (such as an address,
telephone number, or Social Security Number) and posting it online for harassment or other purposes—may incur penalties
under a federal statute restricting the disclosure of personal information. The unlawful access of communications—such as
emails and texts—might potentially violate statutes such as the Wiretap Act. Finally, one frequently used prosecutorial tool
relevant to the cybercrime context is the federal wire fraud statute, 18 U.S.C. § 1343, which authorizes criminal penalties for
knowing or willing participation in a scheme to defraud using interstate wires. The wire fraud statute provides an additional
statutory tool to prosecute some conduct that may also violate the CFAA, and an alternate tool to charge electronic fraud that
does not involve unauthorized computer access as required by the CFAA’s cyber-fraud provisions.
The ubiquity of computers—and the myriad ways in which they may be used or targeted by criminals—means there is no
shortage of cybercrime issues of potential legislative interest to Congress. For example, Congress may wish to consider
creating new criminal penalties for conduct like doxing or trafficking in botnets (networks of compromised computers used
to perpetrate various cybercrimes). Congress may also be interested in establishing additional penalties for cybercrimes with
particular targets such as those impacting critical infrastructure. Alternatively, Congress may seek solutions outside of
criminal law to provide for other means of responding to cybercrimes—as in the case of legislative proposals that would
explore or facilitate hacking back against cyber attackers. In recent Congresses, Members have introduced proposals on each
of these topics.

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

Introduction
Computers are more prevalent than ever before.1 Their ubiquity has made them a favored tool for,
and target of, criminals.2 In 2022—the most recent year for which data is available—the FBI’s
Internet Crime Complaint Center received 800,944 reported complaints of cybercrime with
potential “losses exceeding $10.3 billion.”3 Numerous headline-grabbing incidents further
underscore the frequent and evolving connection between computers and crime. For example, in
May 2021, a ransomware attack prompted the Colonial Pipeline Company to shut down its
network temporarily, impacting gasoline availability and prices4 before the company reportedly
paid a ransom of over $4 million worth of Bitcoin.5 In January 2022, the International Committee
of the Red Cross announced that cyber attackers had obtained “personal data belonging to more
than 515,000 people worldwide” from its systems.6 In March 2022, hackers reportedly stole
cryptocurrency valued in the hundreds of millions of dollars from a service called Ronin.7 In
December 2022, federal authorities arrested two Queens, New York residents, whom they alleged
conspired with Russian hackers to “hack the electronic taxi dispatch system” at John F. Kennedy

1 According to the United States Census Bureau (Census Bureau), by one measure, only 8% of households had a

computer in 1984. MICHAEL MARTIN, U.S. CENSUS BUREAU, COMPUTER AND INTERNET USE IN THE UNITED STATES:
2018, at 4 (2021), https://www.census.gov/content/dam/Census/library/publications/2021/acs/acs-49.pdf. According to
the same report, 92% of households had a computer in 2018. Id. The prevalence of computers may also be inferred
from the estimated number of computerized devices such as smart appliances and fitness trackers connected to the
Internet of Things (IoT)—by one account, there will be 21.5 billion such active devices connected to the IoT by 2025.

International Airport and used their unauthorized access to charge drivers a fee to skip the taxi
queue.8
The world of computer-based crime extends beyond financially motivated hacking. Examples
abound of criminals using computers and the internet to threaten9 and stalk,10 among other things.
Conceptually, the true scope of cybercrime or computer crime depends in part on definitions.11
Depending on the context, “cybercrime” might refer specifically to crimes requiring the use of a
computer, such as hacking, or to traditional crimes when they involve use of a computer or the
internet, like harassment.12 This report uses the term cybercrime somewhat broadly to include
both crimes unique to the computer context and some traditional crimes that may be committed
using computers.13 The report focuses mainly on the Computer Fraud and Abuse Act (CFAA)—a
primary tool in prosecuting cybercrimes like hacking and ransomware attacks at the federal
level.14 The report discusses key CFAA terms and summarizes its substantive prohibitions, then
provides an overview of remedies and penalties under the statute. Many cybercrimes may
implicate federal statutes other than, or in addition to, the CFAA.15 Thus, the report briefly
discusses some of these crimes, such as cyberstalking, and identifies statutes that may be used to

15 Given the large number of federal criminal provisions, it is not possible to provide a comprehensive overview of
federal laws that may apply to every example of crime involving computers. See, e.g., Van Buren v. United States, 141
S. Ct. 1648, 1669 (2021) (Thomas, J., dissenting) (“The number of federal laws and regulations that trigger criminal
penalties may be as high as several hundred thousand.”).

prosecute them at the federal level. The report concludes with a discussion of congressional
considerations.

The Computer Fraud and Abuse Act
Congress was prescient about the ubiquity of cybercrime nearly 40 years ago when it enacted the
CFAA—a civil16 and criminal law that prohibits a range of computer-based acts.17 While a
number of federal statutes may be relevant to combatting nefarious computer activities such as
those discussed above,18 the CFAA is perhaps the most relevant.19Among other things, the CFAA
prohibits a person from trespassing into, damaging, or acquiring information from certain
categories of computers, assuming the user lacks authorization for that conduct.20 Prosecutors
invoke the CFAA to combat a variety of malign computer-based activities.21

History of the CFAA
By many accounts, the history of the CFAA begins with a movie—the 1983 thriller WarGames22
starring Matthew Broderick.23 In WarGames, Broderick’s character, a rebellious high school
student, nearly starts World War III when he accidentally accesses the computer system
controlling the United States nuclear arsenal, mistaking the system for an interactive video
game.24 The movie’s depiction of the dangers of the computer age—where even nuclear
annihilation could be a few keystrokes away—was not lost on policy makers.25 According to one
16 This report cites to civil CFAA opinions despite focusing on cybercrime, as “most of the published cases interpreting

§ 1030 arise in the civil context rather than the criminal context.” KERR, supra note 12, at 31. Further, courts “must
interpret the statute consistently, whether [they] encounter its application in a criminal or noncriminal context.” hiQ
Labs, Inc. v. LinkedIn Corp., 31 F.4th 1180, 1200 (9th Cir. 2022) (quoting Leocal v. Ashcroft, 543 U.S. 1, 12 n.8,
(2004); see also ORIN S. KERR, COMPUTER CRIME LAW 75 (3d ed. 2013) (“Courts generally use civil and criminal
interpretations of federal statutes interchangeably absent an indication that Congress intended a contrary approach.”).
17 H.R. REP. NO. 98-894, at 10 (1984) (“[B]y combining the ubiquity of the telephone with the capability of the
personal computer, a whole new dimension of criminal activity becomes possible.”).
18 For example, relevant provisions might include, among others, federal laws criminalizing wire fraud under 18 U.S.C.
§ 1343, cyberstalking under 18 U.S.C. § 2261A, the interception of electronic communications under 18 U.S.C. § 2511,
or the unlawful access of stored communications under 18 U.S.C. § 2701. See infra “Other Cybercrimes.”

important” of the “wide array of statutes that address the full life cycle of a national security cyber threat”); Michael L.

report, after viewing WarGames at Camp David, President Ronald Reagan asked advisers and the
chairman of the Joint Chiefs of Staff whether the plot of the movie was possible.26 The CFAA is
sometimes “said to be the [eventual] result of their deliberations,”27 although congressional
interest in computer crimes may be traced back at least as far as the 1970s.28
The first major federal computer-crime enactment came in the form of the Counterfeit Access
Device and Computer Fraud and Abuse Act of 1984 (the 1984 Act).29 With exceptions, the law
prohibited three subsets of computer-based conduct: (1) obtaining national security information
through unauthorized computer access; (2) obtaining financial information through unauthorized
computer access; and (3) trespassing into a government computer and “knowingly us[ing],
modif[ying], destroy[ing], or disclos[ing] information” on that computer.30 The 1984 Act was
relatively narrow,31 and the Department of Justice (DOJ) expressed concern that it made computer
crime prosecutions difficult.32 In 1986, Congress substantially amended the 1984 Act, and the
modern CFAA has many of its roots in that 1986 amendment.33 Among other things, the 1986
amendment modified intent requirements and prohibited new categories of conduct including
password trafficking, damaging computers, and accessing computers with intent to defraud.34
Since 1986, Congress has amended the CFAA on numerous occasions,35 broadening both the
scope of conduct prohibited by the statute and the scope of computers protected.36 Today, the
CFAA is the main federal37 computer misuse statute.38

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

Overview of the CFAA
Key CFAA Terms
Although prosecutors may use the CFAA to charge hacking,39 and courts and observers have
described the CFAA as an anti-hacking statute,40 the word “hacking” does not appear in any of its
various provisions.41 Instead, the statute criminalizes several categories of conduct that include
many types of computer hacking as well as a variety of other computer-based activities.42
Generally, the CFAA prohibits certain conduct that is carried out by an individual “without
authorization” or who “exceeds authorized access,” and that involves a computer or a “protected
computer.”43 Two criminal provisions impose liability for conduct relating to “damage” to a
computer.44 Thus, the scope of the CFAA turns largely on the meaning of these terms, which are
discussed below.

Computer
The CFAA broadly45 defines “computer” as any “electronic, magnetic, optical, electrochemical,
or other high speed data processing device performing logical, arithmetic, or storage functions,”
including “any data storage facility or communications facility directly related to or operating in
conjunction with such device.... ”46 The CFAA excludes only automated typewriters, typesetters,
portable hand held calculators, and similar devices from its definition of computer.47 These
limited exceptions “show just how general” the statute’s definition of computer is.48 As one court
explained, the definition includes any device with an electronic data processor, of which there are
numerous examples.49 Thus, under the CFAA, computers include not only laptops and desktops,
but also a wide array of computerized devices ranging from cellphones to objects embedded with
microchips, such as certain microwave ovens, watches, and televisions.50

Protected Computers
Several provisions of the CFAA specifically concern “protected computers.”51 Among other
things, the CFAA defines protected computers as those that are either “exclusively for the use of a
39 See infra Section “Prohibited Conduct Under the CFAA.”
40 E.g., United States v. Nosal (Nosal I), 676 F.3d 854, 857 (9th Cir. 2012); Evtimov, supra note 23, at 904.
41 See 18 U.S.C. § 1030 (proscribing various conduct without use of the word “hacking”).
42 Id.

financial institution or the United States Government” or that are “used in or affecting interstate
or foreign commerce or communication.... ”52 Courts have construed the latter phrase to include
any computer connected to the internet.53 Thus, most modern computing devices are subject to
the CFAA’s protections, including devices such as smart appliances and fitness trackers connected
to the Internet of Things54—“a system of interrelated devices connected to a network and/or to
one another, exchanging data without necessarily requiring human-to-machine interaction.”55
Another important type of computer that fits within the definition of protected computer is a
server—a computer that manages website data and other information.56 For example, one court
concluded that the web servers storing and sharing the member data of a large social media
website qualified as protected computers.57

Without Authorization and Exceeds Authorized Access
The CFAA applies only if the defendant acts “without authorization” or “exceeds authorized
access.”58 For example, Section 1030(a)(2) prohibits intentionally accessing a computer without
authorization or in excess of authorization and obtaining information from a financial institution,
the federal government, or a protected computer.59 Other provisions contain nearly identical
requirements.60

52 Id. § 1030(e)(2). A 2020 amendment to the CFAA expanded the definition of “protected computer” to include any

computer that “is part of a voting system; and ... is used for the management, support, or administration of a Federal
election; or ... has moved in or otherwise affects interstate or foreign commerce.” Defending the Integrity of Voting
Systems Act, Pub. L. 116-179, 134 Stat. 855 (2020) (codified in relevant part at 18 U.S.C. § 1030(e)(2)(C)).
53 See, e.g., Van Buren v. United States, 141 S. Ct. 1648, 1652 (2021) (interpreting the definition of protected computer
in the context of one subsection of the CFAA to include “all computers that connect to the Internet”); hiQ Labs, Inc. v.
LinkedIn Corp., 31 F.4th 1180, 1195 (9th Cir. 2022) (“The term ‘protected computer’ refers to any computer ‘used in
or affecting interstate or foreign commerce or communication[]’—effectively any computer connected to the Internet.”
(quoting 18 U.S.C. § 1030(e)(2)(B)) (internal citations omitted)).
54 Although federal cases specifically examining the CFAA’s applicability in the context of the Internet of Things are
scarce, a number of observers have concluded that internet-enabled objects qualify as protected computers. Orin S.

In one case, federal prosecutors used the CFAA to charge defendants who allegedly gained unauthorized access to Ring
smart devices. Indictment, United States v. Nelson and McCarthy, No. 2:22-cr-00598-JAK (C.D. Cal. Dec. 16, 2022).
Another example from case law is United States v. Peterson. 776 F. App’x 533 (9th Cir. 2019). In Peterson, the U.S.
Court of Appeals for the Ninth Circuit considered a vagueness challenge to a condition of supervised release imposed
on a defendant convicted of possessing child pornography. Id. at 533. The condition at issue restricted the defendant
from accessing a computer as defined by the CFAA. Id. at 534. In agreeing with the defendant that the condition was
potentially overbroad, the court observed that a wide range of objects fall within the definition of computer under the
CFAA, including “refrigerators with Internet connectivity, Fitbit™ watches” and certain automobiles. Id. at 535 n.3.
Although the court did not discuss these devices in relation to the phrase “protected computer,” it described them in a
manner that would satisfy the definition of protected computer under the CFAA; as the court indicated, Internet of
Things devices are (1) computers (2) connected to the internet. Id. at 534. For a similar example, see United States v.

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

While the CFAA repeatedly uses the phrases “exceeds authorized access” and “without
authorization,” the statute does not fully define either phrase.61 In fact, the statute offers no
definition for “without authorization.”62 The CFAA does explain that “exceeds authorized access”
means “access[ing] a computer with authorization and us[ing] such access to obtain or alter
information in the computer that the accesser is not entitled so to obtain or alter,” but that
definition hinges on the meaning of the undefined phrase “with authorization.”63
On a more fundamental level, the meaning of authorization—the common concept in “exceeds
authorized access” and “without authorization”—is also undefined by the CFAA.64 As a result,
case law is still developing with respect to what it means to be an authorized computer user.
In hiQ Labs, Inc. v. LinkedIn Corp., the Ninth Circuit65 suggested that authorization depends on
the computer systems at issue and described three categories.66 The first category encompasses
computers where authorization is not required for access in the first place.67 For example, the
Ninth Circuit said that computers that are “open to the general public” to access fall in this
category.68 The category potentially includes servers for publicly accessible websites, since a
“defining feature of public websites is that their publicly available sections lack limitations on
access; instead, those sections are open to anyone with a web browser.”69 The second category is
comprised of computers “for which authorization is required and has been given.”70 This category
might include, for example, scenarios where an employer provides an employee with password
credentials to enter a company computer.71 Third, there are computers or areas of computer
systems “for which authorization is required but has not been given.”72
The third category poses a crucial question: in what way must the owner of a computer restrict
access so that authorization is not given?73 Federal case law on this question is unresolved. In the
2021 opinion Van Buren v. United States, which marked the Supreme Court’s first significant
foray into the CFAA, the Court described limits on authorization as “gates.”74 The Van Buren
Court explained that assessing authorization under the CFAA is “a gates-up-or-down inquiry”
where “one either can or cannot access a computer system, and one either can or cannot access
certain areas within the system.”75 Van Buren did not define “gate” but seemed to assume that

technological limitations76 such as password requirements constitute a “gate” or limitation on
access.77 In a footnote, however, Van Buren left open the possibility that other gates may exist as
well, including “limits contained in contracts or policies.”78 Beyond this discussion, the Court left
uncertainty as to what means may be used to limit authorization for CFAA purposes.79 In other
words, an unresolved question is what “gates” effectively limit a user’s authorization.80
However, in many respects, Van Buren appears to foreclose imposing CFAA liability for mere
violations of Terms of Service agreements (ToS)—contractual restrictions on computer use.81 The
Van Buren Court held that the CFAA does not criminalize accessing computers for unauthorized
purposes.82 Thus, to the extent a contractual restriction such as a ToS limits the purposes for
which an individual may access information on a computer—such as an employer policy limiting
access to a system for business purposes—violating such restrictions would not incur CFAA
liability under Van Buren.83
Delineating the concept of authorization, and its limits, requires reference to the statutory phrases
“exceeds authorized access” and “without authorization,” which describe when an individual
lacks authorization for CFAA purposes.84 Both phrases are discussed below.
Without Authorization: As noted, the CFAA offers no definition for “without authorization.”85
However, at least in theory, Congress seemingly intended for “without authorization” to apply to
outsiders such as hackers,86 who are “wholly lacking in authority to access or use [the relevant]
computer.”87 Federal courts have generally interpreted “without authorization” to refer to

76 Some observers use the term “code-based” to describe technological limitations, e.g., Bellia supra, note 73, 1457, but

the Court has used the phrases “code-based” and “technological” interchangeably with respect to limitations on
authorization. Van Buren, 141 S. Ct. at 1659 n.8.
77 It questioned only whether other types of gates beyond technological limitations may also exist. See Van Buren, 141
S. Ct. at 1659 n.8 (“For present purposes, we need not address whether this inquiry turns only on technological (or
‘code-based’) limitations on access, or instead also looks to limits contained in contracts or policies.” (emphasis
added)).

CFAA prosecution for mere terms of service violations. See generally, e.g., United States v. Drew, 259 F.R.D. 449, 467
(C.D. Cal. 2009). Also prior to Van Buren, there was an unresolved circuit split over whether the CFAA could impose
criminal liability for ToS violations, as a result of conflicting interpretations of the breadth of the phrases “without
authorization” and “exceeds authorized access.” Compare, e.g., EF Cultural Travel BV v. Zefer Corp., 318 F.3d 58, 62
(1st Cir. 2003) (“A lack of authorization could be established by an explicit statement on the website restricting
access.”) with, e.g., United States v. Nosal (Nosal I), 676 F.3d 854, 863 (9th Cir. 2012) (“Instead, we hold that the

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

outsiders,88 and the Supreme Court appears to have approved of that conclusion in its 2021
opinion in Van Buren v. United States.89
Following Van Buren, a number of federal courts have examined what “gates” may cause
someone to be without authorization to access a computer. In hiQ Labs, Inc. v. LinkedIn Corp.,
the Ninth Circuit concluded that “the CFAA’s prohibition on accessing a computer ‘without
authorization’ is violated when a person circumvents a computer’s generally applicable rules
regarding access permissions, such as username and password requirements, to gain access to a
computer.”90 Thus, the Ninth Circuit held that an entity was not without authorization in violation
of the CFAA when it scraped data from a publicly-accessible website despite a cease and desist
letter.91 The court further held that “the concept of ‘without authorization’ does not apply to
public websites” in general.92 Using Van Buren’s “gates” metaphor for limits on authorization, the
Ninth Circuit explained that with respect to a “computer hosting publicly available webpages, that
computer has erected no gates to lift or lower in the first place.”93 According to the Ninth Circuit,
“[w]ith regard to websites made freely accessible on the Internet . . . the concept of ‘without
authorization’ is inapt.”94
Some federal district courts appear to have embraced a less restrictive interpretation of “without
authorization” than the Ninth Circuit.95 For instance, one court examined Van Buren and rejected
the assertion that “hacking a password is the only way that one can obtain access ‘without
authorization.’”96 That court concluded that a reasonable jury could determine that an individual
is “without authorization” when he accesses a webpage that is not password protected, but that he
believes was intended to be “password protected based on the obviously sensitive nature of the
information” on the page, and when he gained access by “guessing their likely URLs.”97 In an
unpublished opinion, one federal district court also concluded that an individual can be without
authorization if he accessed a computer in violation of ToS and multiple cease and desist letters.98
Subsequent to Van Buren, at least one federal district court has concluded that termination of

employment may revoke authorization and leave the former employee without authorization to
access a computer previously accessed by virtue of that employment.99
Exceeds Authorized Access: The meaning of the phrase “exceeds authorized access” long
divided federal courts.100 Prior to Van Buren, some federal appellate courts, including the First,101
Fifth,102 Seventh,103 and Eleventh104 Circuits, had adopted a broad view of the CFAA where “the
concept of ‘exceeds authorized access’ may include exceeding the purposes for which access is
‘authorized.’”105 In contrast, several other courts, including the Second,106 Fourth,107 and Ninth108
Circuits, had more narrowly interpreted “exceeds authorized access,” based on an understanding
that the CFAA’s central purpose is to criminalize hacking. These courts applied CFAA liability
only to those who lacked any authorization to access a computer or website109 or who were
“authorized to access only certain data or files” but accessed “unauthorized data or files.”110
In Van Buren, the Court appears to have interpreted the CFAA’s scope in a manner roughly
consistent with courts that had applied a narrow interpretation of the statute—reading “exceeds
authorized access” to exclude an individual who uses a computer for an inappropriate reason.111
The Van Buren court concluded that a police officer did not exceed authorized access when he
used a law enforcement database, which he was authorized to use “only for law enforcement
purposes,” to search for license plate information for personal profit.112 Thus, pursuant to Van
Buren, in order to “exceed authorized access” in violation of the CFAA, an individual must access
an area of a computer or information on a computer that is completely “off limits to him,” as

opposed to accessing a computer or information that he is entitled to use in at least some
circumstances.113

Damage
The CFAA defines “damage” to mean “impairment to the integrity or availability of data, a
program, a system, or information,”114 which occurs, for example, when a hacker causes a
computer to behave in a manner contrary to the intentions of its owner.115 Thus, an act that causes
damage under the CFAA may include “clearly destructive behavior such as using a virus or worm
or deleting data ... [b]ut it may also include less obviously invasive conduct, such as flooding an
email account.”116 For example, one federal court concluded that damage occurred as a result of
an orchestrated effort to bombard a company’s “sales offices and three of its executives with
thousands of phone calls and e-mails,” which diminished the ability of that company to use their
systems.117

Prohibited Conduct Under the CFAA

to unauthorized computer access with an intent to defraud.118

the United States Government pursuant to an Executive order or statute to require protection
against unauthorized disclosure for reasons of national defense or foreign relations.... ”121
According to DOJ, examples of national security information under § 1030(a)(1) could include
“classified information obtained from a Department of Defense computer or restricted data
obtained from a Department of Energy computer.”122 In practice, the provision has been rarely
invoked, if at all,123 perhaps because prosecutors may charge offenses involving national security
information under federal espionage statutes that overlap with § 1030(a)(1).124
Prosecutions under § 1030(a)(1) require the government to establish several elements beyond a
reasonable doubt. First, the government would need to prove that the defendant obtained the
national security information by knowingly125 accessing a computer without authorization or in
excess of authorization.126 Section 1030(a)(1) broadly covers all computers, as opposed to just
protected computers127—for example, those exclusively used by financial institutions or
connected to the internet.128 Second, a § 1030(a)(1) violation requires the government to establish
that the defendant had reason to believe that the information could cause “injury to the United
States” or benefit “any foreign nation.”129 There is little case law expounding on this element, but
DOJ has indicated that the element can likely be satisfied where “the national security
information is classified or restricted” and the defendant was aware of that fact.130 Finally, the
government must prove that the defendant “willfully communicate[d], deliver[ed], transmit[ted]
or ... retain[ed]” the national security information, or attempted to do so, or caused the
communication, delivery, or transmission of national security information.131 This element is
broad, and by its own terms includes a range of activities including the failure to return national

disclosure of covered classified information. E.g., 18 U.S.C. §§ 793, 794, 798; see also COMPUT. CRIME & INTELL.

125 Although the CFAA does not define “knowingly,” and despite a dearth of case law on § 1030(a)(1), a Senate report

Obtaining Information by Unauthorized Computer Access, 18 U.S.C. § 1030(a)(2)
Section 1030(a)(2)134 generally prohibits accessing a computer without authorization or in excess
of authorization and obtaining information in certain circumstances. Although at first glance, it
could appear that to “obtain information” might refer specifically to misappropriation or theft of
information, the concept is much broader.135 As interpreted by courts, “obtaining information”
includes “mere observation of the data” such as looking at or reading information on a screen.136
The government has invoked § 1030(a)(2) in a variety of prosecutions,137 including in the case of
several individuals for “breaking into computer networks of prominent technology companies and
the U.S. Army” and stealing “more than $100 million in intellectual property,”138 two
Massachusetts men for stealing social media accounts and cryptocurrency through unauthorized
computer access,139 and an Italian citizen for “hack[ing] into thousands of computers without
permission [and] ... gaining access to all of the information stored on those computers.”140

way.141 First, for § 1030(a)(2) to apply, the information must be obtained from either a financial
institution,142 the federal government, or “any protected computer.”143 As discussed, any computer
connected to the internet suffices. Second, § 1030(a)(2) requires intentional access to a computer
by the defendant, “rather than mistaken, inadvertent, or careless” access.144 However, the intent
requirement is a low bar to prosecution because intent to obtain information is not required;
instead, all that is required is intent to access a computer without authorization or in excess of
authorization.145 Third, the defendant’s access must be without authorization or in excess of
authorization—elements that are discussed above. Before Van Buren, this requirement arguably
did little to limit the expansive scope of § 1030(a)(2), at least in jurisdictions that had adopted a
broad interpretation of the phrase “exceeds authorized access.”146 However, by limiting “exceeds
authorized access” to exclude an individual who uses a computer for an unapproved reason, Van
Buren solidified the element as a more meaningful limit on § 1030(a)(2) prosecutions.147 As
discussed, Van Buren reversed a § 1030(a)(2) conviction on these grounds—concluding that a
police officer who was authorized to access information from a law enforcement database for
official purposes only, did not exceed authorized access in violation of § 1030(a)(2) by accessing
information from that database for other purposes.148

Government Computer Trespassing, 18 U.S.C. § 1030(a)(3)
Section 1030(a)(3)149 generally prohibits intentionally accessing a government computer without
authorization. The provision establishes “a simple trespass offense,”150 which at common law
often refers to an unsanctioned entry onto the land of another, regardless of whether that entry
causes any harm.151 Unlike the previous two CFAA prohibitions, the crux of a § 1030(a)(3)

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

violation is unauthorized entry into a government computer, and the provision does not require
that the defendant do anything with, or obtain anything from, the covered computer once he has
accessed it.152 The provision is seldom invoked by prosecutors, possibly because it overlaps
significantly with § 1030(a)(2), which imposes stricter penalties.153
There are two ways the government can establish a § 1030(a)(3) violation.154 First, the
government may demonstrate that the defendant accessed a “nonpublic computer of a department
or agency of the United States” used exclusively by the federal government.155 A nonpublic
computer includes one for internal use, such as the data servers of a federal agency.156 The term
nonpublic computer excludes, however, public-facing government computers, internet servers,
and websites, such as those offering public services or information.157 Second, the government
may establish a § 1030(a)(3) violation where the defendant accesses a “nonpublic computer of a
department or agency of the United States,” if that computer is used in part by the federal
government and the defendant’s “conduct affects that use.”158 A computer used in part by the
federal government might include, for example, a private company’s computer on which the
federal government has an account.159 In practice, “[a]lmost any network intrusion will affect the
government’s use of its computers because any intrusion potentially affects the confidentiality
and integrity of the government’s network and often requires substantial measures to assure the
integrity of data and the security of the network.”160
Regardless of the nature of the § 1030(a)(3) violation, the government must prove that the
defendant’s access was intentional and without authorization.161 The intent requirement is
identical to the one in § 1030(a)(2). Although the meaning of “without authorization” is also
discussed above,162 it is notable that the statute excludes liability where the defendant’s conduct
merely exceeds authorized access.163 Based on legislative history, it appears that such language

involves additional requirements such as notice to a person that he is trespassing, followed by that person’s knowing
refusal to vacate the area in which he is trespassing. E.g., CONN. GEN. STAT. § 53a-107.

was omitted to foreclose criminal liability against those who have some authorization, like federal
employees approved to use a government computer, but who do so in an unapproved manner.164

Computer Fraud, 18 U.S.C. § 1030(a)(4)
Section 1030(a)(4)165 is an anti-fraud provision, which makes it a crime to “knowingly and with
intent to defraud, access[] a protected computer without authorization, or exceed[] authorized
access” and obtain anything of value, or obtain use of the computer itself if that use is worth at
least $5,000 a year.166 Prosecutors have used § 1030(a)(4) to charge a variety of fraudulent
activities involving computers, including the use of a lottery terminal to falsely generate winning
tickets,167 a phishing scheme that netted “hundreds of thousands of dollars,”168 and a plot to use
misappropriated computer credentials to inflate grades at two universities.169
To prove a violation of § 1030(a)(4), the government must first establish that the defendant
“knowingly and with intent to defraud, access[ed] a protected computer without authorization, or
exceed[ed] authorized access.”170 The statute does not define what it means to act knowingly and
with intent to defraud in the context of § 1030(a)(4).171 However, in the context of a civil
§ 1030(a)(4) claim, one federal court has indicated that “intent to defraud” means to act “willfully
and with specific intent to deceive or cheat, usually for the purpose of getting financial gain for
one’s self or causing financial loss to another.”172 Further guidance on the meaning of “knowingly
and with intent to defraud” may be found in the legislative history of § 1030(a)(4), which notes
that the identical standard is also employed in 18 U.S.C. § 1029 (governing credit card fraud).173
164 As noted in S. REP. NO. 99-432, at 7 (1986):

The Committee wishes to be very precise about who may be prosecuted under the new subsection
(a)(3). The Committee was concerned that a Federal computer crime statute not be so broad as to
create a risk that government employees and others who are authorized to use a Federal
Government computer would face prosecution for acts of computer access and use that, while
technically wrong, should not rise to the level of criminal conduct. At the same time, the
Committee was required to balance its concern for Federal employees and other authorized users
against the legitimate need to protect Government computers against abuse by “outsiders.”
165 18 U.S.C. § 1030(a)(4) imposes criminal liability on whoever:
[K]nowingly and with intent to defraud, accesses a protected computer without authorization, or
exceeds authorized access, and by means of such conduct furthers the intended fraud and obtains
anything of value, unless the object of the fraud and the thing obtained consists only of the use of
the computer and the value of such use is not more than $5,000 in any 1-year period.

refers broadly to wrongdoing rather than to the specific elements of common law fraud. See, e.g., Hanger Prosthetics &
Orthotics, Inc. v. Capstone Orthopedic, Inc., 556 F. Supp. 2d 1122, 1131 (E.D. Cal. 2008) (“The term ‘defraud’ for

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

In the context of § 1029, at least one federal appellate court has concluded that § 1029 requires
proof of the defendant’s “intent to deceive and cheat, which means the government must prove
that the defendant had the intent to deprive a victim of money or property by deception.”174
There are two additional requirements for violations of § 1030(a)(4). First, the government must
prove that in accessing the protected computer, the defendant furthered the fraud.175 In other
words, the access must be “directly linked to the intended fraud.”176 Thus, § 1030(a)(4) does not
govern frauds where the computer use is incidental—for example, where an individual simply
uses the computer for record keeping or to “add up his potential ‘take’ from the [fraud].”177
Second, the government must prove that the defendant obtained “anything of value.”178 That
element is “easily met if the defendant obtained money, cash, or a good or service with
measurable value.”179 One “typical item of value” is data,180 but merely viewing information may
not suffice on its own.181 Rather, as at least one court has concluded, the information must be
valuable not merely in the abstract, but specifically to the defendant “in light of a fraudulent
scheme.”182 Thus, information may not be a thing of value when viewed only to “satisfy idle
curiosity.”183
Computer use, in and of itself, also may be a thing of value for the purposes of § 1030(a)(4), but
only if that use is worth at least $5,000 a year.184 The concept of computer use as a thing of value
is underdeveloped in case law, but a Senate report accompanying the 1986 Amendment to the
CFAA provides some indication that computer use may be a thing of value where it reduces
computer availability that would otherwise generate revenue for the computer owner through
usage fees paid by valid users.185 Although at least one observer has suggested that this idea is
outmoded given the modern prevalence of computers and the corresponding decrease in the value
of computer use,186 DOJ has suggested that it may still be possible for computer use to meet the
$5,000 threshold in the case of recurring or continuing use of an expensive computer.187 In any
event, the $5,000 threshold for fraud solely resulting in computer use is intended to prevent §
1030(a)(4) from encompassing mere computer trespass in most cases.188 As the same 1986 Senate
report observed, if every trespass were thought of as “an attempt to defraud a service provider of

computer time,” it would obliterate the distinction between § 1030(a)(4) and the CFAA provisions
that prohibit trespass.189 In practice, it is difficult to invoke § 1030(a)(4) against a computer
trespasser in the absence of other conduct, because courts may be reluctant to infer adequate
proof of an intent to defraud from mere unauthorized computer access or even observation of
data.190 Rather, for at least one federal court, unauthorized access must be coupled with “the
showing of some additional end—to which the unauthorized access is a means.”191

Damaging a Computer, 18 U.S.C. § 1030(a)(5)
Broadly speaking, § 1030(a)(5)192 prohibits a variety of acts that result in damage to a computer,
including:
•

•

knowingly causing the transmission of “a program, information, code, or
command,” and thereby “intentionally caus[ing] damage without authorization to
a protected computer;” and
intentionally accessing a protected computer without authorization, and thereby:
o recklessly causing damage, or
o causing damage or loss.

Subsection 1030(a)(5) may be used to prosecute many of the activities that are commonly
associated with hacking, such as the transmission of viruses or worms193 and unauthorized access
by intruders who delete files or shut off computers.194 The provision may also be used to
prosecute the perpetrators of Distributed Denial of Service (DDoS) attacks,195 which occur, for
example, when an attacker overwhelms a server’s ability to process legitimate requests by
overloading the server with a flood of illegitimate traffic.196 The government has invoked §
1030(a)(5) in a variety of prosecutions, such as those of a Russian national for deploying malware

The first act that § 1030(a)(5) criminalizes—specifically, under subsection (A)—is to “knowingly
cause[] the transmission of a program, information, code, or command” and thereby
“intentionally cause[] damage without authorization, to a protected computer.”201 The CFAA does
not define “transmission,”202 but the phrase likely “encompasses a range of hacking activities,
such as ‘[t]he transfer of operational or confidential information,’ ‘malicious software updates,’
‘code injection attacks,’ DDoS, and the ‘embedding of malicious code’ or malware.”203
Transmission may occur through use of the internet or physical media like compact discs.204

Cybercrime and the Law: Primer on the Computer Fraud and Abuse Act

Some courts have gone so far as to conclude that the exact means of transmission is irrelevant,
focusing instead on whether the program, information, code, or command caused damage.205 The
CFAA also does not define the phrase “program, information, code, or command.”206 The phrase
seemingly includes “all transmissions that are capable of having an effect on a computer’s
operation,” such as worms, “software commands (such as an instruction to delete information),”
and “network packets designed to flood a network connection or exploit system
vulnerabilities.”207
To prove a § 1030(a)(5)(A) violation, the government must establish dual mental states on the
part of the defendant. First, the government must prove that the defendant’s transmission was
knowing.208 The CFAA does not define “knowing,”209 but it almost certainly excludes accidental
transmission—for example, in the case of an unsuspecting user who forwards an email with
malware attached in a file or link.210 Second, the government must prove that the defendant
intentionally caused damage to a protected computer without authorization.211 The meanings of
“protected computer,” “without authorization,” and “damage” are discussed in detail above.
According to at least one court, the requirement of intent to cause damage in the context of
§ 1030(a)(5)(A) means that the defendant had the “conscious purpose of causing damage ... to
[the relevant] computer.”212
Other violations of § 1030(a)(5) may occur where a defendant intentionally accesses a protected
computer without authorization and causes damage, even if he does not intend to cause such
damage.213 However, for such unintended damage to amount to a § 1030(a)(5) violation, it must
either be reckless or result in loss.214 Although the CFAA does not define what it means to
recklessly cause damage, in general the “normal meaning of reckless in the criminal law (unlike

the civil law) is that the defendant disregarded ‘a risk of harm of which he is aware.’”215 Case law
specific to the CFAA provides few illustrations, but an individual may recklessly cause damage to
a computer if he is aware of the risk that his unauthorized computer access may cause damage
and proceeds anyway in a way that does indeed damage the computer.216 The CFAA defines
“loss” as “any reasonable cost to any victim, including the cost of responding to an offense,
conducting a damage assessment, and restoring the data, program, system, or information to its
condition prior to the offense, and any revenue lost, cost incurred, or other consequential damages
incurred because of interruption of service.”217 Federal courts disagree on whether proving
interruption of service—such as computer systems or files being rendered unavailable—is a
prerequisite to demonstrating loss.218 In other words, some courts construe loss to include
reasonable costs caused by offenses regardless of whether those offenses involve service
interruption, but other courts more narrowly interpret loss under the CFAA as requiring service
interruption.219

Password Trafficking, 18 U.S.C. § 1030(a)(6)
Section 1030(a)(6)220 is a rarely used221 provision of the CFAA designed to protect computer
passwords.222 The provision is “aimed at penalizing conduct associated with ‘pirate bulletin
boards,’ where passwords are displayed that permit unauthorized access to others’ computers.”223
Specifically, the law, assuming an appropriate jurisdictional nexus discussed below, makes it a
crime to traffic “knowingly and with intent to defraud” in “any password or similar information

through which a computer may be accessed without authorization.”224 For the purposes of
§ 1030(a)(6), “traffic” means to “transfer, or otherwise dispose of, to another, or obtain control of
with intent to transfer or dispose of.”225 According to at least one court, “trafficking” under
§ 1030(a)(6) may include the “very common act of giving someone else your password,” but such
behavior “becomes illegal” only where the other elements of §1030(a)(6) are satisfied and where
“the password can enable the password recipient to access a computer without authorization.”226
Based on the definition of “traffic,” a defendant must intend to transfer or dispose of the
passwords or similar information.227 “Knowingly with intent to defraud” is the same standard
used in § 1030(a)(4), discussed above, and generally refers to acts undertaken with the knowledge
that defrauding another is a likely consequence, and the intent that such fraud should actually
occur.228 One federal court concluded that intent to defraud “in the § 1030(a)(6) context requires
more than the intent to impermissibly give access to another.”229 Thus, in that case, the court
concluded that the act of sharing a password without permission—even if it potentially violated a
license agreement—did not “rise to an inference of any ‘intent to defraud’” without additional
factual allegations of fraud.230 “Password[s] or similar information”231 is a broad category
intended to include not “only a single word that enables one to access a computer,” but also
“longer more detailed explanations on how to access others’ computers.”232
For § 1030(a)(6) to apply, the defendant’s actions must satisfy one of two jurisdictional hooks.
First, § 1030(a)(6) could apply where the “trafficking affects interstate or foreign commerce.”233
Although undefined by the CFAA and underdeveloped in case law, at least some courts
examining civil § 1030(a)(6) claims appear to have construed the interstate or foreign commerce
requirement broadly.234 For example, for at least one court, trafficking involving the internet
could satisfy the requirement.235 Second, § 1030(a)(6) may also apply where the defendant
traffics in passwords or similar information that would allow unauthorized entry into a “computer
... used by or for the Government of the United States.”236 Again there is no statutory definition
and little interpretive case law, but according to DOJ the “plain meaning [of the phrase] should
encompass any computer used for official business by a federal government employee or on
behalf of the federal government.”237 However, it is at least possible that the provision only

applies to passwords for executive branch agencies. That is because unlike other CFAA
provisions, § 1030(a)(6) does not specify that a government computer is one used by any
“department or agency of the United States”—a phrase that the CFAA specifically defines as
including legislative, executive, and judicial branch computers.238 Thus, the use in § 1030(a)(6) of
the phrase “computer.... used by or for the Government of the United States” might be interpreted
to have a meaning narrower than the phrase “computer[s] of a department or agency of the United
States” used elsewhere in the CFAA.239

Threats and Extortion, 18 U.S.C. § 1030(a)(7)
Section 1030(a)(7)240 prohibits certain extortionate threats concerning a protected computer, such
as threats to cause damage to, or disclose confidential information from, a protected computer
unless given money or a thing of value.241 The provision has been described as “a high-tech
variation on old fashioned extortion.”242 Although a number of other federal criminal statutes also
prohibit extortionate threats, the CFAA’s legislative history suggests that Congress’s concern in
enacting this provision was that other “extortion statutes, which protect against physical injury to
person or property, [might not] cover intangible computerized information.”243 In particular, the
Senate report accompanying the 1996 Amendment to the CFAA noted concern with threats
against computer systems such as “situations in which hackers penetrate a system, encrypt a
database and then demand money for the decoding key.”244 Prosecutors have invoked
§ 1030(a)(7) to charge a variety of threats against computer systems themselves, such as
ransomware plots that use software to encrypt the victim’s computer files (rendering them
unavailable) until payment is received to unlock those systems.245 The government has also relied
238 18 U.S.C. § 1030(e)(7) (“[T]he term ‘department of the United States’ means the legislative or judicial branch of the

Government or one of the executive departments.... ”).
239 Given the lack of interpretive case law, this possibility remains speculative. DOJ has noted that “used by or for the
Government of the United States” also appears in § 1030(a)(3) and that the plain meaning of the phrase “should
encompass any computer used for official business by a federal government employee or on behalf of the federal
government.” COMPUT. CRIME & INTELL. PROP. SECTION, CRIM. DIV., U.S. DEP’T OF JUST., supra note 12, at 51. There
are differences between the use of the phrase in § 1030(a)(3) and § 1030(a)(6), however. Unlike § 1030(a)(6), the
language of § 1030(a)(3) applies only where the unauthorized access is of “any nonpublic computer of a department or
agency of the United States.” 18 U.S.C. § 1030(a)(3) (emphasis added). Thus, § 1030(a)(3) incorporates a phrase
defined by the CFAA to include computers of all three branches of government, supra note 238, whereas § 1030(a)(6)
does not.

or foreign commerce any communication containing any-(A) threat to cause damage to a protected computer;
(B) threat to obtain information from a protected computer without authorization or in excess of
authorization or to impair the confidentiality of information obtained from a protected computer
without authorization or by exceeding authorized access; or
(C) demand or request for money or other thing of value in relation to damage to a protected
computer, where such damage was caused to facilitate the extortion.

on § 1030(a)(7) to prosecute instances in which computers are not the subject of the threat, but
rather the means of extortion. For instance, prosecutors have brought charges under § 1030(a)(7)
against a hacker who obtained “sensitive records and information” from victim computers, which
he threatened to release unless paid a ransom.246 As another illustration, federal prosecutors
invoked § 1030(a)(7) in charging a former government employee who used stolen passwords to
obtain “sexually explicit photographs ... from victims’ email and social media accounts,” which
he “threatened to share ... unless the victims ceded to certain demands.”247
Section 1030(a)(7) specifically prohibits three categories of extortionate threats. First, the
provision criminalizes “threat[s] to cause damage to a protected computer.”248 Threats to cause
damage might include threats to “interfer[e] in any way with the normal operation of the
computer or system in question, such as [by] denying access to authorized users, erasing or
corrupting data or programs, slowing down the operation of the computer or system, or
encrypting data and then demanding money for the key.”249 Second, § 1030(a)(7) proscribes
“threat[s] to obtain information from a protected computer without authorization or in excess of
authorization or to impair the confidentiality of information obtained from a protected computer
without authorization or by exceeding authorized access.”250 In other words, this second category
includes extortionate threats to obtain information through unauthorized access to a protected
computer, or to disclose information already obtained through unauthorized access to a protected
computer.251 For example, an individual may fall within this second category when he threatens to
hack into a protected computer and obtain sensitive information.252 He may also fall within the
category if he has already hacked into the computer and obtained the information, and he
subsequently threatens to disclose it. This latter category could include double extortion
ransomware schemes where an attacker not only uses ransomware but also breaches a computer
system, steals sensitive information, and threatens to disclose that information if ransom is not
paid.253 Third, it is a crime under § 1030(a)(7) to issue a “demand or request for money or
[an]other thing of value in relation to damage to a protected computer, where such damage was
caused to facilitate the extortion.”254 An example of this type of threat is the use of ransomware to

extort payment in exchange for providing the decryption key for the victim’s files,255 and
prosecutors have used the subsection to charge such conduct.256
There are two important limitations to § 1030(a)(7) as it pertains to all three categories of threats.
First, for § 1030(a)(7) to apply, the defendant must have acted “with intent to extort from any
person any money or other thing of value.”257 In general, extortion refers to “obtaining something
or compelling some action by illegal means, as by force or coercion.”258 In the context of
§ 1030(a)(7), courts have found the requisite intent to extort where, for example, defendants
wrongfully obtained confidential information or credentials and demanded money for their
return.259 However, it may not be necessary to establish “that the defendant actually succeeded in
obtaining the money or thing of value, or that the defendant actually intended to carry out the
threat made.”260 Second, the defendant must have transmitted the threat “in interstate or foreign
commerce”261—for example, by transmitting the threat through the internet or between computers
in two different states.262

Remedies and Penalties
The CFAA authorizes a number of remedies for violations of its various prohibitions. Most
obviously, violations of the CFAA provisions discussed above are subject to various criminal
penalties of fines and imprisonment.263 The nature of those penalties varies based on the specific
subsection at issue (see Table 1).264 For example, the maximum prison term for first-time CFAA
offenders is one year under § 1030(a)(3),which governs certain acts of trespassing in government
computers,265 but five years under § 1030(a)(4), which is the main anti-fraud provision in the

CFAA.266 The distinction between first-time and repeat offenses is also relevant in the CFAA (see
Table 1). For instance, under § 1030(a)(1)—which prohibits obtaining and disclosing national
security information through unauthorized computer access—a violation is generally subject to a
maximum prison term of ten years, a fine, or both.267 If that violation occurs after another CFAA
offense, it is subject to a maximum prison term of twenty years, a fine, or both.268 Within some
CFAA provisions, the relevant penalties also depend on the gravity of the defendant’s conduct
(see Table 2; Table 3; Table 4). For example, under § 1030(a)(2)—prohibiting obtaining
information in certain circumstances—the penalties are stiffer if the value of the information
obtained is greater than $5,000 (see Table 2).269 The CFAA provision prohibiting damage to
computers—§ 1030(a)(5)—offers another illustration (see Table 3; Table 4). It authorizes longer
prison terms for certain outcomes, such as when a violation results in bodily injury or death.270
The prison terms covered in this section are the maximum authorized by the CFAA for each
offense; the sentence actually imposed on a given defendant may be less and is a determination
informed by the United States Sentencing Guidelines.271
With respect to fines, the amounts will vary based on the corresponding prison term authorized by
each CFAA subsection. Unless the underlying statute specifies otherwise, for felonies—violations
of statutes authorizing a maximum prison term of more than one year272—the default maximum
fine level is the greater of $250,000 ($500,000 in the case of organizations) or twice the gain or
loss associated with the offense.273 The default maximum fine level for misdemeanors varies.274 A
federal statute classifies the misdemeanor offenses contained in the CFAA as Class A
misdemeanors because they are punishable by up to one year of imprisonment.275 The default
maximum fine level for Class A Misdemeanors not resulting in death is the greater of $100,000
($200,000 in the case of organizations) or twice the gain or loss associated with the offense.276
