Ukraine and Russia Report Hacked Emergency Apps Causing False 'Radiation' Alerts

Residents in Kyiv and other parts of Ukraine recently experienced confusion and alarm after emergency alert applications disseminated false warnings of radiation, chemical threats, and even street fighting. The "Air Alert" app, widely used by Ukrainians for genuine threat notifications, was compromised on Sunday, November 1, 2026, leading to these erroneous messages, which sometimes contained spelling errors and mentioned a hacking group. Ukraine's Air Force quickly reassured the public that there was no actual radiation threat and attributed the incident to "hostile interference," with Ukraine's Centre for Strategic Communications directly blaming Russia for the cyberattack.

Hours later, Russia also reported that its Emergency Ministry's mobile application had been hit by a "massive cyberattack," resulting in the spread of false information to its users on Monday, November 2, 2026. While Russia's ministry did not publicly identify the perpetrator of the attack on its system, a Russian Telegram channel with ties to security services suggested that the hacking group "Hitcore" claimed responsibility for the incident in Ukraine, though this could not be independently verified.

Authorities in both nations emphasized that their broader public alert infrastructures, including traditional air-raid sirens and official communication channels, remained fully operational despite the app breaches. Officials advised citizens to rely on these verified sources and to disregard the false notifications circulating through the compromised applications. The timing of the Ukrainian false alerts also coincided with the expiration of a humanitarian ceasefire in the Kherson region.
