Ukrainian alert app partly restored after cyberattack spread false warnings
Povitriana Tryvoha issued false warnings about nuclear and chemical danger on 1 November. Developers say they temporarily stopped the service before a partial overnight restoration.
Ukraine’s Povitriana Tryvoha air-raid warning app suffered unauthorised interference, according to its development team. Ukrainska Pravda reported on 2 November that developers had disabled push notifications and temporarily stopped the app. The previous evening, false messages warned of radiation, chemical threats, street fighting and an Oreshnik missile attack. The warnings were written in Russian.
In a follow-up at 02:18, Ukrainska Pravda, again citing the development team, reported that service was partly restored. Yellow and red threat levels were available on the map again and push notifications had resumed. Displaying targets on the map remained temporarily disabled. Developers said they were adding security measures and stated that the app does not store or use personal data.
