Ukraine and Russia reported apparent cyberattacks affecting their mobile emergency alert applications during the night of Sunday, November 1, into Monday, November 2. The incidents led to false notifications being sent to millions of users, including warnings about alleged nuclear threats and other dangers.
In Ukraine, the Air Alert app, which is used to notify residents about Russian air attacks, issued messages referring to radiation threats, chemical attacks and possible clashes in the streets of Kyiv. One notification also mentioned the Russian Oreshnik hypersonic missile and suggested that it was on its way.
Ukraine’s Air Force said the application had apparently been subjected to malicious interference. Authorities stressed that there was no nuclear radiation threat and advised residents to follow information published through official channels. The app was temporarily suspended while the issue was addressed and was later restored.
A few hours later, Russian authorities said that the mobile application of the Ministry of Emergency Situations had also been targeted in a major cyberattack. According to the ministry, attackers sent false information to users, including claims that nuclear warheads had been launched against several regions.
The ministry said it was working to restore the service but did not identify those responsible. It also described the mobile app as a supplementary information channel, adding that other public warning systems continued to operate normally.
There is currently no confirmation that the incidents in Ukraine and Russia were connected, and the perpetrators have not been independently identified. The attacks highlight how the manipulation of digital emergency systems can create immediate confusion among civilians, particularly in countries where residents depend on these platforms for warnings about attacks and instructions to seek shelter.
