Fake nuclear warnings issued after Ukrainian and Russian air alert apps hacked

On Sunday night, air alert apps in Ukraine and Russia were the targets of cyberattacks, resulting in the distribution of fraudulent warnings of attacks, including nuclear ones. Ukraine's widely used app disseminated red-level air raid warnings throughout the country, while some residents in regions like Kyiv received additional notifications concerning radiation, chemical attacks, and street fighting.

A short time later, Russian authorities announced that a comparable app had been hacked, with fake alerts, some of which contained profanity, being activated. It remained uncertain who was responsible for the cyberattacks and if the incidents were linked. Many Ukrainian residents are accustomed to receiving nearly nightly alerts concerning incoming Russian missile and drone assaults.

Some admitted to The BBC that, four and a half years into the conflict, they had disabled the app. Following Sunday night's breach, Ukraine's air force advised citizens to rely on alternative official sources. The air force's post on Telegram stated: "The Air Alarm application may have been subjected to hostile interference. There is no radiation threat!

Remain calm and follow our updates on our [Telegram] channel." The government informed that it temporarily disabled the app for maintenance, claiming it had "apparently been compromised." Certain of the deceptive alerts were composed in Russian, which would have signaled to numerous users that the messages were not genuine.
