Emergency alert applications in Ukraine and Russia were compromised by hackers who disseminated false warnings regarding nuclear threats and air raids, based on information published by Security Affairs.
The cyberattack occurred late Sunday, triggering widespread panic as users received fabricated notifications about radiation leaks, chemical attacks, and street fighting. In Ukraine, the Air Alert app sent red-level warnings across the country, including messages referencing Russian ballistic missiles. The Ministry of Digital Transformation of Ukraine temporarily disabled the application for maintenance to address the security breach. Simultaneously, Russia reported a massive cyberattack on its own emergency notification system, which allegedly pushed fake alerts claiming that Ukrainian drones had launched nuclear warheads.
While officials in both nations worked to restore services and calm the public, the incident highlights critical vulnerabilities in national emergency communication infrastructure. Cybersecurity experts noted that such attacks represent a dangerous escalation, as disabling compromised systems during an active conflict leaves civilians without timely warnings for genuine threats. Authorities in both countries urged citizens to rely on secondary communication channels, such as sirens and official government messaging services, until the integrity of the digital platforms could be fully verified.
