   Ukraine and Russia report cyberattacks on emergency alert apps

   Hackers sent fake nuclear warnings on emergency alert apps in Ukraine and Russia, causing unease but not widespread panic. The attacks occurred within hours of each other on November 1-2, 2026. Ukrainian President Volodymyr Zelenskyy confirmed Ukraine hacked back after Russia's cyberattack. The incidents highlight the ongoing cyber warfare between the two countries.
