Ukraine: Alert App Hacked to Broadcast False Nuclear and Chemical Warnings

Hackers compromised Ukraine's public alert application to broadcast false warnings of nuclear and chemical threats before authorities stepped in to reassure the public.

Hackers breached Ukraine's public air-alert mobile application and distributed false warnings of severe security threats, ynet and Croatian network N1 reported. Residents received fabricated alerts warning of a chemical attack, nuclear danger, elevated radiation levels, and street clashes, urging them to stay indoors.

The Ukrainian Air Force and local authorities clarified that the system had been compromised, stressed that there was no radiation threat, and urged the public to remain calm. Meanwhile, Moscow claimed that a cyberattack also targeted a Russian alert app, broadcasting false messages about drones armed with nuclear warheads.

The identities of those responsible for the cyberattacks have not yet been released.
