## Key points

- False nuclear and chemical alerts targeted people in Ukraine and Russia.
- Ukraine’s air raid app serves about 6.7 million people daily.
- Rival hacking groups claimed responsibility, but one claim remains unverified.

## Summary

Hackers sent false air raid and emergency warnings to people in Ukraine and Russia in what appeared to be a tit-for-tat cyber attack. The alerts falsely claimed nuclear or chemical threats and risked causing panic, highlighting how attacks on public warning systems can undermine trust during wartime.

Ukraine’s air raid app, used by about 6.7 million people a day, was hit just after 11pm on Sunday; its air force said there was no radiation threat, and the app was temporarily suspended. Hours later, Russia’s emergency ministry reported a cyberattack on its mobile app, with a regional message telling residents that nuclear warheads had been launched and to stock up on food for three weeks. A newly formed group called Hitcore claimed the attack on Ukraine, while pro-Ukrainian group Atesh claimed the Russian attack, which could not be independently verified; the incidents followed the end of a six-day ceasefire.
