Keylogger Prosecutions Under Us Law
Keylogger Prosecutions Under U.S. Law: Overview
Keyloggers are software or hardware tools designed to record keystrokes on a computer or device, often used to capture sensitive information like passwords, credit card numbers, or private communications without the user’s consent.
Because of their invasive nature, unauthorized use or distribution of keyloggers often violates multiple U.S. laws related to computer crime, wiretapping, privacy, and fraud.
Relevant Laws Frequently Applied in Keylogger Cases
Computer Fraud and Abuse Act (CFAA), 18 U.S.C. § 1030: prohibits unauthorized access to computers or exceeding authorized access.
Wiretap Act (Title III), 18 U.S.C. §§ 2510-2522: prohibits interception of electronic communications without consent.
Electronic Communications Privacy Act (ECPA), 18 U.S.C. § 2701 et seq.: protects the privacy of electronic communications.
Identity Theft and Fraud statutes, e.g., 18 U.S.C. §§ 1028, 1343 (fraud by wire).
State computer crime and privacy statutes: many states have specific prohibitions on keylogger use.
Key Legal Issues in Keylogger Prosecutions
Unauthorized access or interception: Installing or using keyloggers without the consent of the device owner.
Intent: Whether the defendant intended to steal, defraud, or invade privacy.
Distribution and sale: Liability for creating or selling keylogger software.
Use in further crimes: Keylogger use often ties into broader schemes like identity theft, hacking, or fraud.
Consent exceptions: Some keylogger use with user consent is legal, e.g., parental control or employer monitoring within limits.
