Fake nuclear alerts trigger panic as hackers breach Ukraine and Russia emergency apps
Unauthorized messages warned of radiation and missile strikes, causing temporary service suspensions in both nations.
By Yuki Melnyk ·
Ukrainian and Russian citizens received conflicting emergency warnings overnight as hackers infiltrated national alert systems. The intrusions generated false alerts about nuclear attacks and chemical weapons, forcing authorities in both countries to pause digital services while they investigated the breach.
Ukraine’s air raid alert channel confirmed that unauthorized parties had accessed the application. The service was temporarily suspended after posts appeared claiming high radiation levels and chemical attacks in Kyiv. The fraudulent messages were written in Russian and contained spelling errors. They referenced the hacking group Hitcore, which claimed responsibility according to the Russian Telegram channel Mash.
One specific alert stated that Russia had launched a hypersonic Oreshnik missile. The message declared a national nuclear alert across Ukraine. The Ukrainian air force issued a statement noting that the app appeared to be under enemy influence. Officials reassured the public that there was no radiation threat and instructed residents to follow official updates.
Officials restored the Ukrainian service and confirmed that all public alert mechanisms, including air raid sirens, were functioning properly. They issued all-clear messages to calm residents who had relied on the digital channel for daily missile and drone strike warnings. The restoration of service marked the end of the immediate disruption in Ukraine.
Hours later, Russia’s Ministry of Emergency Situations reported a similar cyberattack on its mobile application. Users received false warnings that nuclear warheads had been launched against the entire country. The alerts urged people to stockpile three weeks of food and take shelter in cellars. The ministry described the app as a supplementary information source rather than a primary warning channel.
A bogus message reviewed by Reuters displayed a casual tone, including colloquialisms and expletives. The text described Russia as a swamp. The ministry largely dismissed the impact of the breach on the public. This incident occurred on November 1, 2026, affecting millions of users who depend on these apps for safety during the ongoing conflict.
The simultaneous breaches highlight the vulnerability of digital infrastructure in both nations. Authorities in Kyiv and Moscow confirmed the attacks and restored normal operations. The fake alerts created a brief but intense period of confusion for working families in both countries.
