Zelensky says Ukraine hacked Russia's emergency alert app after fake nuclear warnings hit Ukrainians
Hackers hijacked Ukraine's Air Alert app late on November 1, 2026, and sent false warnings of a nuclear threat, radiation, chemical attacks, and street fighting to users across the country. Hours later, attackers sent fake alerts about launched nuclear warheads through the mobile app of Russia's Emergency Situations Ministry, which said the message reached 33 of Russia's 89 regions. Ukrainian President Volodymyr Zelensky told PBS News on November 2 that Ukraine hacked the Russian app in response to the attack on its own system.
