By John D. Kirby, Former U.S. Federal Prosecutor · September 27, 2026

The digital age has brought with it a new wave of criminal activity, particularly in the realm of cybercrime. As a former U.S. federal prosecutor and San Diego federal criminal defense attorney, I have seen firsthand the complexities and severity of federal cybercrime charges, particularly those arising under the Computer Fraud and Abuse Act (CFAA). This comprehensive blog article aims to provide an in-depth understanding of the CFAA, the charges it can bring, and the strategies for defending against them.

The Scope of the Computer Fraud and Abuse Act

The Computer Fraud and Abuse Act, enacted in 1986, was one of the first federal laws designed to address the growing issue of computer-related crime. The CFAA makes it a federal offense to access a computer without authorization, exceeding authorized access, or causing damage to a computer. This broad scope encompasses a wide range of activities, including hacking, data breaches, and unauthorized access to sensitive information.

Types of Charges Under the CFAA

Charges under the CFAA can vary depending on the nature of the offense. Common charges include:

• Hacking into a protected computer system.
• Exceeding authorized access to a computer to obtain information.
• Using a computer to commit fraud.
• Intentional transmission of viruses or malicious code.

Potential Penalties for Violating the CFAA

The penalties for violating the CFAA can be severe. Under the CFAA, individuals can face up to five years in prison for a first offense, and up to 20 years for a second offense. In cases where the offense involves identification theft or fraud, the penalties can be even more severe. Additionally, fines can be substantial, and a conviction can have long-lasting consequences on an individual's reputation and career.

Key Defenses in Federal Cybercrime Cases

Defending against federal cybercrime charges requires a thorough understanding of both the law and the specific facts of each case. Some common defenses include:

• Arguing that the access was authorized or that there was no intent to commit a crime.
• Claiming that the defendant's actions were protected under the First Amendment, such as in the context of cybersecurity research or activism.
• Challenging the adequacy of the evidence or the government's interpretation of the CFAA.

The Importance of an Experienced Defense Attorney

Federal cybercrime cases are complex and often involve significant technical evidence. An experienced defense attorney is essential to navigate the intricacies of these cases. A skilled attorney will have a deep understanding of the CFAA, the technology involved, and the procedures of the federal court system. This expertise can make a significant difference in the outcome of a case.
