Ukraine says air alert system hacked after false radiation warning in Kyiv
Ukraine’s Emergency Alert App Targeted by Cyber‑Misinformation, Authorities Say
Kyiv, Ukraine — In a striking example of cyber‑warfare, Ukraine’s official air‑raid alert app sent a series of false emergency messages over the weekend, warning residents of a “radiation hazard” and a “chemical attack” in the capital. The deceptive alerts, which appeared on Sunday, urged people to stay inside and even listed Kyiv and other districts on the app’s map as being under a nuclear emergency.
The first bogus notification read: “There is a radiation hazard alert in Kyiv. Do not go outside!” A second message said: “There is a chemical attack alert in Kyiv. Do not go outside!” The app also showed false nuclear alerts, claimed threats from Russia’s hypersonic Oreshnik missile, and fabricated reports of street fighting in Kyiv. In addition to the digital messages, loudspeakers in the city’s streets played a pre‑recorded announcement that repeated the same warning to residents.
Ukrainian officials quickly identified the incident as a cyber‑attack. “The air alert app appears to have been subjected to enemy influence,” the Ukrainian Air Force told followers on Telegram. “There is no radiation threat! Stay calm and follow our updates on our channel!” the statement read. The Center for Strategic Communications, a government agency that monitors information operations, also blamed Russian forces for the intrusion, although no group has claimed responsibility for the attack.
In a separate development, Russia’s Emergencies Ministry announced early Monday that its own mobile application had been hit by a “massive cyberattack” that allowed attackers to transmit false information to the public. “Attention! The mobile application of the Ministry of Emergencies of Russia has been subjected to a massive cyberattack, enabling attackers to send false information to the public,” the ministry posted to Telegram.
The timing of the Ukrainian alerts—just a day after President Volodymyr Zelenskyy warned of a major strike—has intensified speculation about the motives behind the cyber‑campaign. While Ukrainian authorities attribute the breach to Russian interference, no hacker group has publicly claimed responsibility.
Cyber‑security experts say that such attacks are designed to sow confusion and erode trust in government communications amid the ongoing conflict. Whether the misinformation was intended to divert attention from military actions or simply to create panic remains unclear. Nevertheless, both sides have acknowledged the breach and promised to strengthen safeguards against future intrusions.
For residents in Kyiv and other affected areas, the false alarms prompted a surge in calls to emergency hotlines and an uptick in social‑media posts asking for confirmation. Local officials reassured the public that no chemical or radiation threats had been detected, and urged people to rely on official updates from the Ukrainian Armed Forces.
As the war continues, the incident underscores how the front lines have expanded beyond conventional battlefields into cyberspace, where information is now as much a weapon as artillery.
