Hackers hacked apps in Russia and Ukraine that inform the population about threats. Users received false warnings about the danger of a nuclear attack Users of the Ministry of Emergency Situations application received messages at night about the launch of "nuclear warheads in all regions of the country". Media from different regions reported this in reference to readers. The alert contained obscene language and called for stocking up on food for three weeks. Later, the Ministry of Emergency Situations reported that the request was subject to a cyber attack. "The attackers managed to send fake information to the population," the ministry said. The department stated that the public warning system is working as usual. "The hacking of the mobile application did not and cannot have an effect on the operation of the public warning system", since the main channels are alarms and SMS alerts, and the application is only an auxiliary service, the press release said. "Experts from the Russian Ministry of Emergency Situations are taking all necessary measures to restore the normal operation of the mobile application. The situation is under control," the department assured. The night before, the Ukrainian Air Alert app sent messages to users about radiation and chemical dangers, as well as the threat of street fighting. A message in Russian also appeared in the application: "Hello! Now there will be a nuclear alarm throughout Ukraine. Don't worry, Hazel is flying." At the same time, the alarms did not sound, and there were no messages about any threats on the Telegram channel of the Air Force of the Armed Forces of Ukraine. The military later said the app was "hostilely affected" and denied any radiation dangers.
