Computer Fraud and Abuse Act

The Computer Fraud and Abuse Act is a law passed by the United States Congress in 1984 intended to reduce cracking of computer systems and to address federal computer-related offenses. The Computer Fraud and Abuse Act (codified as USC 18 1030 governs cases with a compelling federal interest, where computers of the federal government or certain financial institutions are involved, where the crime itself is interstate in nature, or computers used in interstate and foreign commerce. It was amended in 1986, 1994, 1996, in 2001 by the USA PATRIOT Act, and in 2008 by the Identity Theft Enforcement and Restitution Act. Subsection (b) of the act punishes anyone who not just commits or attempts to commit an offense under the Computer Fraud and Abuse Act but also those who conspire to do so.

The CFAA has specifically defined “protected computers” under USC 18 1030(e)(2) to mean a computer:

  • exclusively for the use of a financial institution or the United States Government, or, in the case of a computer not exclusively for such use, used by or for a financial institution or the United States Government and the conduct constituting the offense affects that use by or for the financial institution or the Government; or
  • which is used in or affecting interstate or foreign commerce or communication, including a computer located outside the United States that is used in a manner that affects interstate or foreign commerce or communication of the United States;

Evolution of the act

PATRIOT Act

The USA PATRIOT Act increased the scope and penalties of this act by:

  • Raising the maximum penalty for violations to 10 years (from 5) for a first offense and 20 years (from 10) for a second offense;
  • Ensuring that violators only need to intend to cause damage generally, not intend to cause damage or other specified harm over the $5,000 statutory damage threshold;
  • Allowing aggregation of damages to different computers over a year to reach the $5,000 threshold;
  • Enhancing punishment for violations involving any (not just $5,000) damage to a government computer involved in criminal justice or the military;
  • Including damage to foreign computers involved in US interstate commerce;
  • Including state law offenses as priors for sentencing; and
  • Expanding the definition of loss to expressly include time spent investigating and responding (this is why it is important for damage assessment and for restoration)
  • Selling a computer that has had a virus or currently has a virus is committing a federal offense that will be carried out with a sentence of up to 5 years in a federal state penitentiary, and,or a fine of up to $7,000

Identity Theft Enforcement and Restitution Act

The Identity Theft Enforcement and Restitution Act enhanced the jurisdiction of the Computer Fraud and Abuse Act by:

  • Eliminating the requirement in USC 18 1030(a)(5) that the defendant’s action must result in a loss exceeding $5,000;
  • Adding a provision to USC 18 1030(c)(4) that makes it a felony to cause damage to ten or more computers;
  • Expanding jurisdiction for cases involving theft of information from computers by eliminating the requirement that information must have been stolen through an interstate or foreign communication;
  • Enhancing prosecution for extortion related to computers by expanding USC 18 1030(a)(7) to criminalize not only explicit threats to cause damage to a computer, but also threats (1) to steal data on a victim’s computer, (2) to publicly disclose stolen data, or (3) to not repair damage the offender already caused to the computer;
  • Amending USC 18 3663(b) to make clear that restitution orders for identity theft cases may include an amount equal to the value of the victim’s time spent in remediation of the actual or intended harm of the identity theft or aggravated identity theft offense;
  • Creating a criminal offense for conspiring to commit a computer hacking offense under USC 18 1030;
  • Broadening the definition of "protected computer" in USC 18 1030(e)(2)(b) to the full extent of Congress' commerce power by including those computers used in or affecting interstate or foreign commerce or communication;
  • Providing a mechanism for forfeiture of property used in or derived from violations of USC 18 1030.
