Ukraine and Russia say air raid alert apps hit by cyberattacks after truce ends

Officials said false nuclear and chemical warnings briefly reached millions of app users as both countries blamed hostile cyberattacks.

  • Official civilian alert mobile applications in both Ukraine and Russia were hit by coordinated cyberattacks, briefly disseminating false emergency warnings to millions of citizens across both nations.
  • Ukrainian defense officials confirmed that their national air raid alert system sent out erroneous notifications warning of false radiation hazards, chemical threats, and imminent strikes by Russian hypersonic Oreshnik missiles.
  • Hours later, Russia’s Emergencies Ministry announced that its public emergency app came under a "massive cyberattack" that resulted in unauthorized push notifications and false drone strike warnings.
  • The digital disruptions occurred immediately following the conclusion of a localized humanitarian ceasefire in the eastern Kherson region, which expired without reported kinetic violations or an extension agreement.
  • Cyber security agencies in Kyiv attributed the app breach to hostile Russian influence, while Russian emergency officials stated tech teams were working to neutralize ongoing security breaches to restore system integrity.
