Germany probes Signal cyberattacks; Lambsdorff, FDP politician, known for EU liberal work, now caught in digital security spotlight.
The federal prosecutor's office has identified a suspect, Sergej K., who has been in continuous contact with a Russian intelligence handler since at least May 2025. He is accused of sharing details on German defense contractors, drone tech, NATO convoy movements, and potential sabotage targets, while offering to recruit others. Police have arrested him and will bring him before a judge for pre-trial decisions.
