Russia and Ukraine have both reported cyberattacks targeting their emergency alert apps, with hackers sending fake warnings of nuclear, chemical and radiation threats to mobile phone users.
Russia’s emergency ministry said its app was hit by a “massive cyberattack” that allowed attackers to spread false information to the public While Ukraine’s air raid alert system briefly flashed warnings of a possible nuclear threat and street combat. Ukraine’s Air Force said the incident appeared to involve external interference, while reassuring residents that there was no radiation threat. “The Russian Ministry of Emergency Situations’ mobile app was subjected to a massive cyberattack, which allowed the attackers to distribute fake information to the public,” the ministry said in a statement. It also shared an image showing some of the alerts that had appeared on Ukraine’s air raid warning app and urged residents to disregard any unusual messages they might receive through the application, according to BBC.
Meanwhile, in Russia, the mobile app of the emergency ministry was hit by a massive cyberattack that resulted in the spread of false information to the public, Reuters reported, citing state news agency TASS, which quoted the ministry as saying early on Monday.
