On November 1, the Ukrainian Air Force reported a suspected hacking incident involving its air defense alert application. This app, which is essential for notifying citizens of threats, mistakenly displayed alerts regarding nuclear, chemical weapon threats, as well as potential urban combat situations in Kyiv and other regions. Among the false information presented was a message claiming that Russia had deployed the “Oreshnik” hypersonic missile.
In a statement posted on Telegram, the Ukrainian Air Force warned users that the “Air Alarm” application appeared to have been maliciously interfered with, stating clearly, “There is no radiation threat! Please remain calm, and stay tuned for the latest updates from our channel.”
Ukrainian intelligence agencies confirmed that the application had malfunctioned and urged the public to verify any information regarding air raid threats through alternate channels.
The wave of false alerts began around 22:47 local time, when the first message was sent in Ukrainian, announcing: “Radiation threat. Kyiv has issued a radiation threat alert.”
Just one minute later, another message in Russian proclaimed, “Hello everyone! A nuclear alert will be issued across Ukraine. Don’t worry, it’s just about the ‘Oreshnik’ missile.”
At 22:49, a third alert in Ukrainian warned of a “chemical threat,” stating, “Kyiv is facing a threat of chemical attacks. Please stay indoors.”
Another alert followed shortly after, again at 22:49, announcing the danger of urban combat, with the message: “Urban combat threat. Fighting is taking place in Kyiv. Please do not go outside.”
It wasn’t until over an hour later, at 23:53, that users received a series of “all clear” notifications corresponding to the earlier alerts, reassuring them that the threats had been resolved.
The Ukrainian Center for Combating Disinformation advised the public that if the alert application was not functioning correctly, they should enable notification features on their smartphones, remain alert to air defense sirens, and only rely on information sourced from official channels.
Governors from several other regions in Ukraine also took to Telegram to confirm that the application had indeed been hacked and that there was no actual threat in their areas.
The “Air Alarm” application is supported by Ukraine’s Ministry of Digital Transformation, which previously noted that because the app had apparently been compromised, they had temporarily disabled it for maintenance.
Moreover, Russian news agency TASS reported that on November 2, the Russian Ministry of Emergency Situations indicated that its mobile app had also been subjected to a massive cyberattack, resulting in the dissemination of false information to the public. The ministry is currently working to restore the application.
At this time, it remains unclear whether these two incidents are connected, but both highlight the tensions and cybersecurity vulnerabilities facing nations in the region.
