1. Statutory Overview: America’s Primary Anti-Hacking Law

Enacted in 1986 and broadened through the USA PATRIOT Act and subsequent amendments, the Computer Fraud and Abuse Act (CFAA), codified at 18 U.S.C. § 1030, serves as the cornerstone federal statute governing cybercrime, unauthorized network intrusion, malware deployment, botnets, and digital extortion. Virtually any smartphone, laptop, cloud server, or corporate database connected to the Internet qualifies as a “protected computer” under § 1030(e)(2) because it operates in interstate or foreign commerce.

2. CFAA Subsections & Exact Prison Sentences (§ 1030(c))

Section 1030 divides cyber offenses into seven distinct subsections ((a)(1) through (a)(7)), each paired with escalating first-time and repeat-offender penalties:

CFAA Subsection Prohibited Cyber Conduct First Offense Max Repeat / Aggravated Max
§ 1030(a)(1) Obtaining & transmitting classified national defense / foreign relations data Up to 10 years Up to 20 years
§ 1030(a)(2) Intentionally accessing computer without authorization / exceeding access to get data 1 yr (misdemeanor) or 5 yrs* Up to 10 years
§ 1030(a)(3) Trespassing into a non-public U.S. government computer Up to 1 year Up to 10 years
§ 1030(a)(4) Accessing protected computer with intent to defraud (> $5,000 value) Up to 5 years Up to 10 years
§ 1030(a)(5)(A) Knowingly transmitting code/malware causing damage without authorization 10 yrs (or 1 yr if minor) 20 yrs (or Life if death caused)
§ 1030(a)(5)(B)-(C) Intentionally accessing without authorization recklessly/negligently causing damage 1 to 5 years Up to 10–20 years
§ 1030(a)(6) Trafficking in stolen passwords or access credentials affecting commerce/govt Up to 1 year Up to 10 years
§ 1030(a)(7) Cyber extortion — threatening damage or leaking stolen data for ransom Up to 5 years Up to 10 years

*Note on § 1030(a)(2): A basic violation increases from a 1-year misdemeanor to a 5-year felony if committed for commercial advantage or private financial gain, in furtherance of any criminal or tortious act, or if the value of information obtained exceeds $5,000.

3. Critical Infrastructure & Life-Endangering Enhancements

Under 18 U.S.C. § 1030(c)(4)(E)–(F), penalties escalate dramatically when cyberattacks target hospitals, water utilities, power grids, or emergency networks:

  • Recklessly Causing Serious Bodily Injury: Up to 20 years imprisonment if an offender knowingly or recklessly causes or attempts to cause serious bodily injury during a § 1030(a)(5)(A) attack.
  • Knowingly Causing Death: Any term of years up to life imprisonment if the attacker knowingly or recklessly causes or attempts to cause death.
  • U.S.S.G. § 2B1.1 Cyber Enhancements: Sentencing Guidelines add offense levels when an intrusion disrupts a critical infrastructure system, compromises personal identifying information (PII), or involves specialized cyber tools.

4. The Supreme Court’s Van Buren Rule & Authorized Access

Van Buren v. United States (2021)

Before 2021, federal courts disagreed on whether violating a website’s Terms of Service or an employer’s computer use policy constituted “exceeding authorized access” under the CFAA. In Van Buren, the Supreme Court adopted a “gates-up-or-down” technical test: a person exceeds authorized access only when they obtain information located in particular areas of the computer — such as files, folders, or databases — to which their technical access does not extend. Misusing data you are technically authorized to access for an improper purpose does not trigger CFAA criminal liability (though it may still violate state privacy or trade-secret laws).

5. Defenses in Federal CFAA Prosecutions

  • Authorization / Gates-Open Defense: Demonstrating that the defendant accessed publicly available web endpoints or areas covered by existing credentials without bypassing authentication gates (including hiQ Labs v. LinkedIn public web scraping precedent).
  • Lack of Knowing or Intentional Mens Rea: Automated scripts, misconfigured scanners, or accidental network traffic without intent to damage or intrude fail the statutory intent requirement.
  • Failure to Meet $5,000 Loss Threshold: For felony triggers or civil claims under § 1030(g), disputing inflated corporate incident-response estimates can defeat the statutory damage threshold.

Practical Sentencing Example & Collateral Consequences

Illustrative Scenario: A former IT contractor uses an unrevoked administrator token to access a former employer’s cloud backup vault without authorization and deletes production backups causing $85,000 in recovery expenses. Prosecutors charge § 1030(a)(5)(A) (up to 10 years max). Under U.S.S.G. § 2B1.1, the $85,000 remediation cost (+6 loss levels) combined with a +2 specialized-skill enhancement and +2 loss-of-computer-system adjustment often places a first offender around 18–24 months plus full restitution for forensic incident-response fees.

Collateral Consequences: CFAA felony convictions frequently carry strict supervised-release computer monitoring conditions, employer device bans, and permanent loss of security clearances.

Frequently Asked Questions (18 U.S.C. § 1030 (CFAA))

Is every violation of 18 U.S.C. § 1030 a felony?

No. A basic first-offense unauthorized access to obtain information under § 1030(a)(2)(C) without commercial gain, another felony, or value exceeding $5,000 is a Class A misdemeanor punishable by up to 1 year in prison. Aggravated hacking, malware damage, or repeat offenses escalate to 5, 10, or 20 years.

How did Van Buren v. United States (2021) change the CFAA?

In Van Buren v. United States (2021), the U.S. Supreme Court narrowed 'exceeds authorized access' under § 1030(a)(2). Simply violating an employer's terms-of-use policy to view data you already have technical permission to access is no longer a federal CFAA crime; a user must cross an access gate into files or systems off-limits to them.

What is the federal penalty for ransomware or cyber extortion?

Under 18 U.S.C. § 1030(a)(7), transmitting threats to damage a protected computer or demand money/ransom carries up to 5 years in prison for a first offense and up to 10 years for repeat offenses. When paired with actual damage to hospital or infrastructure networks under (a)(5)(A), penalties rise to 20 years or life.

Can victims sue hackers civilly under the CFAA?

Yes. Under 18 U.S.C. § 1030(g), any person who suffers damage or loss of at least $5,000 in a one-year period (or impairment to medical care, physical injury, or public safety) may file a civil lawsuit for compensatory damages and injunctive relief within 2 years.
