Cyber attacks hit Russia, Ukraine after truce ends

Kyiv, Ukraine – 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.
