VERY IMPORTANT

The Coast Guard is observing malicious activity linked to a cyber-criminal campaign targeting critical infrastructure in Europe and threatening the United States energy sector’s segment in the Marine Transportation System (MTS). These threats were discovered via dark-web posts made by the Russian-based cyber-criminal and hacktivist group known as KILLNET. KILLNET is one of many hacktivist groups whose malicious cyber activity increased in the wake of the Russia’s invasion of Ukraine. The group gained notoriety for their Distributed Denial of Service (DDoS) attacks against numerous U.S. Critical Infrastructure and Government websites.
