Cyberattack on the official air raid alert source: what it means for eTryvoga
Updated 2 November 2026, 02:00 Kyiv time
UPD 2 November, 00:15: alerts are back
The official alert source works correctly again. Air raid alert and all-clear notifications are back, and the map shows current alerts again.Because of the attack on the official alert source, we temporarily stopped sending air raid alert and all-clear notifications, and colours on the map could differ from the real signals.
All notifications work as usual
eTryvoga notifications about air raid alerts, missiles, attack drones, guided bombs, shelling, explosions and other important information keep coming as usual.What happened
On 1 November at about 22:48 Kyiv time, «Povitriana Tryvoha» — the official air raid alert source that eTryvoga also uses — was hit by a cyberattack. False red alerts appeared across almost all of Ukraine. The Air Force said the app was likely subject to hostile interference and that there is no radiation threat.
What we did
The false alerts reached eTryvoga too and were sent as notifications. We removed them, restored the map to its state before the attack, and switched off automatic alerts from the official source while the attack lasted.
Where things stand
On 2 November at 00:15, once the source was working correctly again, we switched automatic alerts back on. The map and air raid alert and all-clear notifications work as usual.
What to do
As always, follow the sirens where you are and the official channels of the Air Force and local authorities. Don’t open suspicious links if they appear in apps. News is in our Telegram.
