Ukraine suspends emergency alert app after false nuclear warnings

Ukraine suspends emergency alert app after false nuclear warnings

Ukraine's Digital Transformation Ministry announced the temporary suspension of the national emergency alert app on 2 November after unknown hackers injected false warnings of a nuclear strike and chemical threat, prompting public alarm. The ministry said the messages were unauthenticated and urged citizens to rely on official channels.

The incident followed a hack reported on 1 November that caused the air-raid alert application to broadcast radiation and chemical alerts across Kyiv. Ukraine's Air Force confirmed there was no real threat, and both Ukrainian and Russian officials later said the alerts were unauthenticated.
