Ukraine’s Air Force has reported a cyberattack targeting the country’s public air raid alert application after the platform circulated a series of false security warnings.
The application briefly displayed notifications suggesting that Kyiv and several other regions were under nuclear and chemical threats, alongside alerts about possible street fighting.
Another misleading notification claimed that Russia had deployed its hypersonic Oreshnik missile, prompting Ukrainian authorities to clarify the situation.
In a statement shared on Telegram on Sunday, the Ukrainian Air Force said the application appeared to have been compromised by hostile actors.
“The air alert app appears to have been subjected to enemy influence,” the military said, assuring residents that there was no radiation threat and advising them to remain calm and follow updates through its official communication channels.
The false notifications were subsequently removed from the application.
Ukraine’s Ministry of Digital Transformation later announced that the platform had been temporarily taken offline, while confirming that alternative public warning systems remained operational.
The ministry added that air raid sirens were functioning normally, ensuring residents could continue receiving emergency alerts through other channels.
Meanwhile, Russia’s Emergencies Ministry reported a separate cyberattack on its mobile application, which resulted in false information being circulated among members of the public.
State news agency TASS reported the incident early Monday, citing the ministry.
It remains unclear whether the cyberattacks targeting the Ukrainian and Russian applications were connected.
