Ukraine air-raid app hacked; false radiation warnings spread

Ukraine's air-raid alert application was apparently hacked on Saturday, pushing false radiation warnings to users as the country faced fresh Russian strikes. The Ukrainian Air Force said the breach had been detected and contained, though the scope of the compromise and the number of users affected remained unclear by Sunday evening.

Hours later, Russian authorities reported a similar breach of their own domestic alert system, with fake warnings distributed inside Russia. The parallel incidents suggest a coordinated campaign or a vulnerability exploited by multiple actors, though no group has claimed responsibility.

The attacks underscore the vulnerability of civilian alert infrastructure in an active conflict. False warnings risk eroding public trust in legitimate emergency notifications at a moment when accurate, rapid communication can mean the difference between evacuation and harm.
