Air-raid alert apps in Ukraine and Russia hit by cyberattacks that pushed out false warnings

1 November 2026

Ukraine's nationwide air-raid alert application sent out false messages on Sunday.
The fake alerts warned of nuclear and chemical threats in and around Kyiv, warned of possible street fighting and claimed that Russia's Oreshnik hypersonic missile had been deployed.
The Ukrainian Air Force said on Telegram that the application appeared to have been subjected to enemy influence and added that there was no radiation threat.
SPRAVDI, Ukraine's Centre for Strategic Communications, said on social media that Russia was behind the hack.
A separate alert application used only in Kyiv was working normally, city authorities said.
Early on Monday Russia's Emergencies Ministry said its own mobile application had been hit by a large cyberattack that spread false information.
The incidents came soon after the localised truce in the Kherson region ended.
