Russia and Ukraine Exchange Reciprocal Emergency App Hacks

The Ukrainian Air Force and the Russian Ministry of Emergency Situations reported reciprocal cyberattacks on their emergency alert systems over the weekend. On November 1, Russian hackers compromised the Ukrainian air raid alert app, sending false notifications to residents in and around Kyiv. These messages warned of imminent chemical and nuclear threats, street combat, and the deployment of Russia's hypersonic Oreshnik missile.

Ukrainian authorities and the Centre for Strategic Communications, SPRAVDI, attributed the breach to Russian influence. Local officials, including the Kyiv City State Administration, moved quickly to reassure the public that no actual radiation threat existed.

In a retaliatory strike on November 2, the Ukrainian resistance movement ATESH hacked the Russian Emergency Situations Ministry application. The breach targeted residents of Voronezh Oblast with fake alerts claiming nuclear warheads were being launched at all Russian regions, urging citizens to hide in basements and stock food for three weeks. Russian local authorities and the Ministry of Emergency Situations confirmed the system had been compromised by a massive cyberattack.

These incidents occurred immediately following the conclusion of a localized ceasefire in Kherson, which had lasted from Tuesday to Sunday and represented the longest truce of the war.
