Emergency Warning Apps in Ukraine and Russia Reportedly Hacked
Official emergency warning apps in both Ukraine and Russia were reportedly hacked, according to authorities. In Ukraine's "Air Alert" app, false warnings about radioactive radiation in Kyiv and chemical weapons attacks were sent late Sunday; the Ukrainian Air Force said the app may have been compromised by the enemy and urged citizens not to click links. Overnight into Monday, Russia reported a massive cyberattack on its own warning app, with attackers sending false information to the population, according to the state news agency Tass citing the civil defense ministry. The timing suggested a possible Ukrainian retaliatory attack, though Russia did not name a suspected culprit. Meanwhile, a six-day ceasefire in the Russian-occupied southern Ukrainian city of Oleshky ended after Russia refused an extension, according to Ukrainian human rights commissioner Dmytro Lubinets. Ukraine also reported territorial gains in October, recapturing 96.2 square kilometers while losing 85.8, and claimed October 2026 was Russia's costliest month since the full-scale invasion with 54,400 Russian casualties.

Ukraine air raid app apparently hacked, users receive false radiation alerts
Ukraine's air raid alert app was apparently hacked on Sunday, briefly warning that Kyiv faced a radiation threat, the Ukrainian Air Force said. The Air Force stated on Telegram that the app had probably been subjected to hostile interference and that there was no radiation threat, urging the public to stay calm and follow official channels. The Ukrainian Central Intelligence Agency reported a failure in the app and urged people to use other sources. Alerts began around 22:47 local time, including messages about a radiation threat, a nuclear alert referencing 'Oreshnik,' a chemical threat, and street fighting in Kyiv, followed by all-clear messages. The Central Intelligence Agency also said the radiation hazard signal was played on loudspeakers in the Lviv region, adding there was no threat. Vinnytsia oblast governor Natalya Zabolotna said there had been a cyberattack and warned users not to click links in the message. The app, supported by the Ministry of Digital Transformation, informs users about defence alerts.
