Botnet Operation Prosecutions
Legal Framework for Botnet Operation Prosecutions
Botnet operations typically violate several federal statutes, including:
Computer Fraud and Abuse Act (CFAA), 18 U.S.C. § 1030 (prohibiting unauthorized access and damage to protected computers)
Wire Fraud Statute, 18 U.S.C. § 1343 (for schemes to defraud using electronic communications)
Conspiracy Statutes, 18 U.S.C. § 371 (for conspiracies to commit offenses)
Identity Theft and Trafficking Laws if personal information is stolen.
Prosecutors target creators/operators of botnets for malware distribution, DDoS attacks, data theft, spam, and fraud.
Penalties can include imprisonment, fines, and forfeiture of equipment.
