Hacker wars: Rival Russian and Ukrainian cyber groups claim credit for attacks on each country’s air raid systems that saw some civilians alerted to fake nuclear and chemical warfare
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.
In short
- 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.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
A strong case for treating the incidents as a serious escalation is that false warnings of nuclear or chemical threats can cause panic, disrupt emergency responses and erode public trust in systems people rely on for safety. In wartime, attacks on civilian alert services can expose ordinary people to risks even when no weapon has been used.
The case against
A cautious case against drawing broader conclusions is that responsibility for both attacks remains unverified, and the available account does not establish who directed them or why. The incidents may be isolated acts by groups claiming attention rather than evidence of a deliberate state-led escalation, so claims about their wider significance should remain tentative.
Explained simply
Ukraine and Russia both use phone apps to send official warnings to the public. In Ukraine, the air raid app alerts people to attacks and is used by millions; Russia’s emergency ministry also sends notices through a mobile app.
The warnings matter because people may rely on them to decide whether to seek shelter or take other safety steps. False alerts can cause panic and make it harder for the public to trust genuine warnings during wartime.
The groups named in reports of the attacks are Hitcore, which says it targeted Ukraine’s app, and Atesh, a pro-Ukrainian group that says it targeted Russia’s. Claims by groups involved in cyberattacks can be difficult to verify independently.
