Both Russia and Ukraine have apps designed to warn the public of incoming drone attacks and other threats. (EPA Images pic)KYIV: Russia said its emergency warnings app came under a "massive cyberattack" on Monday, hours after Ukraine reported a hack in an apparent exchange of blows between the foes, as their longest truce came to an end.
Moscow'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 cyber attacks came as the longest truce of the war, limited to Ukraine's eastern Kherson region, ended on Sunday after Russia refused the offer of an extension, according to Kyiv.
