On February 24, 2022, a deliberate cyber-attack targeted Viasat’s KA-SAT network, leading to a partial interruption of satellite broadband service. The attack primarily affected several thousand customers in Ukraine and tens of thousands across Europe, specifically impacting the 'Tooway' service brand. The incident was confined to a consumer-oriented partition managed by Eutelsat subsidiary Skylogic. Viasat's mobility and government users remained unaffected. Immediate network stabilization efforts were initiated, and the network was largely restored within hours. Ongoing investigations are being conducted in collaboration with Mandiant, law enforcement, and international agencies. No evidence of data compromise or direct impact on the satellite infrastructure has been found. Viasat is working with distributors to restore service, including shipping replacement modems as needed.
