## Key points

- Zelensky confirmed a Ukrainian cyberattack on Russia’s emergency alert app.
- He said it followed the hacking of Ukraine’s Air Alert app.
- Both incidents sent users false warnings, including nuclear alerts.

## Summary

Ukrainian President Volodymyr Zelensky confirmed that Ukrainian hackers targeted a mobile app used by Russia’s Emergency Situations Ministry to send threat alerts. He said the attack was a response to an earlier breach of Ukraine’s Air Alert warning app, framing it as retaliation amid a wider pattern of cyberattacks affecting civilians.

The Air Alert app was hacked on the evening of 1 November, sending users fake warnings about radiation and chemical hazards, street fighting and a nuclear alert. In the early hours of 2 November, users of Russia’s emergency app received false notifications claiming nuclear warheads had been launched at all regions of the country. Zelensky described Russian attacks on Ukrainian systems, including banking and social support services, as numerous.
