“This joint Cybersecurity Advisory (CSA)—authored by the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and National Security Agency (NSA)—is part of our continuing cybersecurity mission to warn organizations of cyber threats and help the cybersecurity community reduce the risk presented by these threats. This CSA provides an overview of Russian state-sponsored cyber operations; commonly observed tactics, techniques, and procedures (TTPs); detection actions; incident response guidance; and mitigations.” reads the joint alert. “This overview is intended to help the cybersecurity community reduce the risk presented by these threats.”

The alert provides information about tactics, techniques, and procedures (TTPs) associated with Russia-Linked threat actors, along with recommendations on incident response and mitigations.
