Ukraine air raid app apparently hacked as users receive false radiation threat, Air Force says
Hours later Russian authorities said its app was also hacked, with fake warnings sent inside the country.
Ukraine's air raid alert app was apparently hacked on Sunday and for a short time said the capital Kyiv was subject to a radiation threat, the Ukrainian Air Force has said.
The alert on Telegram read: "The Air Alarm application has probably been subjected to hostile interference. There is no radiation threat! Stay calm and follow our updates on our channel."
The Ukrainian Central Intelligence Agency said there had been a failure in the app, and urged people to use other sources of information to clarify the situation on the threat of air strikes.
If the alert app is not working, Ukraine's Centre for Countering Disinformation advises the public to turn on notifications on their smartphones, pay attention to sirens, and to only read official sources
