Cyberattacks hit Russia, Ukraine emergency warning apps

Updated / Monday, Getty Ukraine said it suspected its air raid alert system had been compromised Russia and Ukraine have both said their emergency warning apps have been hit . Russia said its app came under a "massive cyberattack" this morning, hours after Ukraine reported a hack in an apparent exchange of blows between the foes, as their longest truce came to an end. The Kremlin's emergencies ministry said hackers posted "false information" on the app, which is designed to warn the public of incoming drone attacks and other threats. Hours earlier, Ukraine said it suspected its air raid alert system had been compromised, after baseless alerts of a radiation threat appeared on the app. The cyberattacks came as the longest truce of the war, limited to Ukraine's eastern Kherson region, ended yesterday after Russia refused the offer of an extension, according to Kyiv. Moscow did not immediately say who was behind the attack on its app, while Ukraine's Center for Strategic Communications SPRAVDI blamed the hack it suffered on Russia. The rare pause in fighting, brokered , had enabled a humanitarian mission to the Russian-occupied city of Oleshky as the war grinds through its fifth year. Evacuees from Russian-occupied Oleshky arrive in Ukraine over the weekend "The ceasefire, which was in effect from 27 October to 1 November, has ended," Ukraine's Parliament Commissioner for Human Rights, Dmytro Lubinets, said. He called the temporary truce "an important step in our joint humanitarian efforts" with Russia. US-mediated talks between Russia and Ukraine are set to resume this month, having been effectively frozen since the United States and Israel launched joint strikes on Iran in February. Ukrainian President Volodymyr Zelensky yesterday said his country would stop hitting Russian oil refineries -- as US counterpart Donald Trump has demanded - if Washington provided Kyiv with powerful Patriot interceptor missiles. Raid alert app hack Kherson regional governor Oleksandr Prokudin warned local people to be particularly vigilant when the ceasefire ended and to "respond immediately to warnings about Russian attacks". "The Air Alarm application has probably been subjected to hostile interference," Ukraine's air force said in a message. "There is no radiation threat." Air force spokesman Yuriy Ignat confirmed to AFP that the app had been hacked. Hours later, Russia's emergencies ministry said its teams were working to fix a "massive cyberattack" which was "enabling attackers to send false information to the public". A Ukrainian military officer, speaking on condition of anonymity, expressed concern that the fighting would be "worse than before" when it resumed.
