Fake nuclear and drone warnings were sent via compromised apps in both countries after a ceasefire in Kherson.

Within minutes of a ceasefire lifting in Kherson, Ukraine’s citizens were pummelled with threatening notifications. Cyberattacks on both Russia’s and Ukraine’s emergency alert apps resulted in fake messages about missile and nuclear strikes broadcast to the public. Officials from both countries confirmed the attacks, which occurred at similar times on Sunday evening. Ukraine’s Air Alert app was hit first, followed by Russia’s Ministry of Emergency Situations app, which issued updates that the apps were restored to normal operation after patching.

Unconfirmed: Exact methods of the cyberattack are not detailed.

Key facts
  • Ukraine's Air Alert app was compromised first, sending fake warnings about street fights and radiation.
  • Russia's app was abused with fake nuclear strike alerts referencing 'Oreshnik' and 'P1-Sun'.
  • Ceasefire in Kherson ended at same time as attacks began.
