Ukraine and Russia accuse each other of hacking emergency alert apps

Ukraine and Russia have accused each other of hacking their emergency alert applications as a local ceasefire in the eastern Kherson region expired, France 24 reported.

Ukraine's air raid alert app was reportedly hacked, sending false radiation threat warnings to users in Kyiv, according to the Ukrainian Air Force and BBC World.

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, while a Ukrainian espionage group claimed fake nuclear strike warnings were sent inside Russia.

Hours later, Russian authorities stated their emergency warnings app was also hacked, with false alerts posted to warn of drone attacks and other threats, as reported by France 24.

The ceasefire, which lasted from October 27 to November 1 and was brokered by US First Lady Melania Trump according to France 24, ended after Russia declined to extend it, Ukraine's Parliament Commissioner for Human Rights said.

Moscow did not immediately identify who was responsible for the cyberattack on its app, while Ukraine's Centre for Strategic Communications attributed the hack on their system to Russia.
