Hackers breach Russian and Ukrainian emergency alert systems with false nuclear warnings

Official emergency alert applications in Russia and Ukraine were successfully breached by unknown hackers who used the platforms to circulate fabricated warnings of nuclear attacks, according to reports on Monday. The unauthorized messages appeared on government-controlled emergency notification systems designed to alert citizens of genuine threats and disasters.

The timing of the intrusions comes amid heightened tensions between Moscow and Kyiv, where real military strikes have become routine. Officials in both countries have not publicly disclosed the full extent of the breaches or identified those responsible for the cyberattacks.

Security experts have warned that compromised emergency alert systems pose serious risks to public safety by eroding trust in official notifications and potentially causing widespread panic. Citizens relying on such applications for genuine safety information may be left unable to distinguish between authentic alerts and fraudulent messages.

The incidents highlight broader cybersecurity challenges facing Eastern European nations, particularly regarding the protection of critical infrastructure. Both Russia and Ukraine have faced sustained cyberattacks throughout their conflict, targeting government systems, utilities and communications networks.

Authorities in both countries have urged residents to verify information through official government channels and to report suspicious alerts to relevant authorities. Investigations into the breaches are reportedly underway.
