Ukraine Air Alarm App Hacked with False Radiation and Street Fight Alerts

Ukraine's official air raid alert mobile application suffered an apparent hostile cyberattack on Sunday night, pushing a series of false emergency notifications to users including fake warnings of a radiation hazard, nuclear alert, chemical threat, and active street fighting in the capital city of Kyiv. The false notifications began at approximately 22:47 local time. The first alert warned of a radiation threat in Kyiv, followed a minute later by a message written in Russian stating a nuclear alert would occur across Ukraine caused by an Oreshnik flight. Subsequent alerts warned of a chemical attack and active street fighting in Kyiv, before clear messages were sent out for each false warning. The Ukrainian Air Force and the Central Intelligence Agency both confirmed the app interference on Telegram, assuring the public that no actual threat existed. Officials noted that the app failure also triggered physical loudspeaker sirens in the Lviv region. Vinnytsia oblast governor Natalya Zabolotna warned citizens on social media not to click any links embedded in the messages, while authorities advised the public to rely exclusively on verified official channels and turn on smartphone notifications.

Context

The Air Alert app is a crucial digital tool supported by the Ministry of Digital Transformation of Ukraine to instantly notify residents of incoming defense alerts. Cyber disruptions targeting critical public infrastructure and communication channels are common tactics during ongoing wartime conflicts.
