All 50 states have computer crime laws; most address unauthorized access or computer trespass. Some state laws also directly address other specific types of computer crime, such as spyware, phishing, denial of service attacks, and ransomware, as shown below.

Computer crime laws encompass a variety of actions that destroy or interfere with normal operation of a computer system. Computer trespass, unauthorized access (or access exceeding permission that was granted to a user), or hacking is breaking into computer systems, frequently with intentions to alter, disable or modify existing settings. When malicious in nature, these break-ins may cause damage or disruption to computer systems or networks. Additional state and federal laws may apply to various other types of computer crimes (e.g., unfair and deceptive practices acts, etc.).
