Both Ukraine and Russia have said they were targeted by cyber-attacks on mobile apps that warn civilians of air threats. The incidents took place overnight between 1 and 2 November 2026.
What happened in Ukraine
On Sunday evening, the command of Ukraine's air force said its warning system had been "hacked by the enemy". For a short time the app sent out erroneous messages: about a possible nuclear and chemical attack on Kyiv and other parts of the country, about the threat of street fighting, and about a Russian Oreshnik ballistic missile.
The command urged people on Telegram to stay calm and stressed that there was no radiation threat. The disruption subsided after a while. Ukraine's Ministry of Digital Transformation said the app was temporarily out of service, but that other warning methods, including air raid sirens, were working normally.
According to TVN24, Ukrainian journalist Oleh Bilecki reported that app users received 122 erroneous messages within seven minutes. Some of them contained a link to a Telegram channel. Piotr Konieczny of the Polish site Niebezpiecznik.pl said that, according to reports, the channel was used to recruit Ukrainians for acts of sabotage. Ukrainians blame Russia for the attack.
Russia reports a similar attack
In the early hours of Monday 2 November, Russia's Ministry of Emergency Situations said its app, which warns of drone attacks and other threats, had been the target of a "massive cyber-attack". According to a statement on Telegram, the attack allowed false information to be spread among the public, and the ministry is working to remove its effects and restore the app. TVN24 reports that a false message said nuclear warheads had been launched towards all regions of Russia.
What is still unknown
The sources we used do not name any independently confirmed perpetrators of either attack. The accusations against Russia from the Ukrainian side come from media reports and have not been confirmed here by an independent investigation. It is also unknown whether the two incidents are linked.
What this means for you
The event has no direct legal or financial consequences for people living in the UK. For those with family or friends in Ukraine, the key point is that the alert turned out to be false and that sirens and other warning systems worked normally. Ukrainian authorities advise following the official air force announcements.
