Tietoevry, a leading European IT services and software company, has been affected by the Akira ransomware attack. The attack, which started in mid-July 2025, exploited a zero-day vulnerability in SonicWall SSL VPN devices. This led to unauthorized access and subsequent encryption of critical data. The ransomware group, Akira, is known for dismantling backups to hinder recovery efforts, causing significant disruption to Tietoevry's operations.
