Background for this topic.

Federal Bureau of Investigation (FBI) is the United States’ principal federal law-enforcement agency and a domestic intelligence authority. In cybersecurity, it investigates cybercrime, digital intrusion, online fraud, and espionage; works with victims and other agencies; and may support disruption operations, prosecutions, or public warnings. FBI references in security news often concern indictments, infrastructure seizures, malware or intrusion advisories, and requests for victim cooperation.

Practitioners can report suspected internet crime through the FBI’s Internet Crime Complaint Center (IC3) or contact a local FBI field office, while preserving relevant logs, messages, and other evidence. FBI engagement can provide threat intelligence, such as indicators of compromise or information about attacker infrastructure, and may affect evidence handling and legal processes. It does not replace containment, recovery, breach assessment, or privacy and regulatory notifications required of the affected organization.
