Russian Hacker Alliance Targeting Denmark in Large-Scale Cyberattack

Russian Legion, an alliance of hacktivist groups (Cardinal, The White Pulse, Russian Partizan, and Inteid), publicly launched "OpDenmark" in late January 2026 and executed coordinated DDoS attacks against Danish government, energy, and healthcare services; the campaign combined DDoS-for-hire traffic with public threats on Telegram to create operational disruption and psychological pressure, and Truesec characterizes the alliance as state-aligned (not state-funded).
