“Ukraine and Russia have both said air alert apps were hacked on Sunday night after fake messages warning of attacks, including nuclear, were sent to users. Ukraine’s widely used app sent red-level air raid warnings across the country, with additional warnings of radiation, chemical attacks, and street fighting sent to some residents in areas including Kyiv. A few hours later, Russian authorities said a similar app was hacked after fake alerts, some of which contained foul language, were triggered. It was unclear who was behind the cyberattacks or whether the two incidents were connected.” (11/02/26)
