Emergency warning applications in Russia and Ukraine were targeted by cyberattacks on Sunday, with hackers distributing fabricated alerts about nuclear strikes, chemical threats and missile launches, according to CNN.
In Ukraine, false notifications warned of nuclear and chemical emergencies in Kyiv and other areas, alongside reports of possible street fighting and Russia's hypersonic Oreshnik missile deployment.
The Ukrainian air force dismissed the warnings, confirming there was no radiation threat. Developers are restoring the app and strengthening its security.
Kremlin spokesman Dmitry Peskov acknowledged the growing cyber threat, citing technological advances, including artificial intelligence.
Although widespread panic was avoided, some users questioned whether official emergency alerts could be trusted after the breaches.
