A warning system was also hacked in Russia, messages about a nuclear threat may have been sent.

Russia reported a cyberattack on its emergency alert system, leading to false alarms about nuclear threats. This incident followed similar alerts in Ukraine, where residents were warned of nuclear and chemical attacks. The Russian Ministry of Emergency Situations stated that the app was targeted in a mass cyberattack, but assured that the overall alert system remained intact. Messages claimed that Ukrainian drones launched nuclear warheads against Russia, urging citizens to stockpile food and seek shelter. The ministry is working to restore the app, emphasizing that alerts are communicated through multiple channels, including sirens and broadcasts.
