Ukraine’s Air Alert app, the air raid warning application supported by the Ministry of Digital Transformation, sent a rapid series of false alerts on Sunday evening, beginning with a radiation threat declared in Kyiv at about 22:47 local time, followed within two minutes by messages in Russian and Ukrainian warning of a nuclear alert, a chemical attack on Kyiv and street fighting in the capital, each then cancelled by individual all-clear messages. The Ukrainian Air Force said on Telegram that the app had probably been subjected to hostile interference, stated there was no radiation threat and urged people to stay calm, while the Vinnytsia regional governor, Natalya Zabolotna, called it a cyberattack and warned users not to click a link in a message. A Ukrainian intelligence body said a radiation hazard signal had also been played over loudspeaker devices in the Lviv region and that there was no radiation hazard, and no official statement attributed the interference to a named attacker.
Ukraine air alert app sends false radiation warnings
Ukraine's Air Alert app sent false radiation, chemical and street fighting warnings for Kyiv on Sunday evening before all-clears followed, in what the Air Force called probable hostile interference with the app.
Why it matters: The app is the warning channel much of Ukraine relies on during Russian strikes, so false alerts of the most feared kind test public trust in the system at the moment it is needed most.
