Overview
- Ukraine’s Air Force says the national air-raid alert system was hacked, causing sirens and fraudulent notifications that warned of nuclear, chemical and street-fighting threats.
- Many users received the fake alerts through the officially supported Air Alert app, a tool developed with the Digital Transformation Ministry and security firm Ajax Systems.
- The Air Force and regional governors warned there is no radiation threat, urged calm and directed residents to follow verified official channels for updates.
- Officials and local governors warned the breach may involve a phishing operation and specifically advised people not to click links in suspicious messages.
- Authorities are conducting forensic and security checks into the incident, and the compromise raises risks that false warnings could erode trust in emergency communications and complicate civilian response.
