February 24, 2022: Update on Viasat Cyberattack

The Feb. 24 incident, which also hit tens of thousands of other fixed broadband customers across Europe, was localized to a single consumer-oriented partition of the KA-SAT network operated on Viasat’s behalf by a Eutelsat subsidiary, Skylogic.
A targeted denial of service attack (DoS) first ended up discovered after high volumes of focused, malicious traffic made it difficult for modems to remain online, said Viasat’s incident summary. The traffic emanated from several SurfBeam2 and SurfBeam 2+ modems and/or associated customer premise equipment physically located within Ukraine.
