In brief
Ukrainian air‑raid alert app issued false warnings on Sunday, citing nuclear, chemical threats and a rumored hypersonic missile, prompting Kyiv officials to deny any radiation danger and blame Russia. Russian authorities also confirmed a massive cyber‑attack on their enterprise but denied responsibility.
On Sunday, October 22, 2026, Ukraine’s nationwide air‑raid alert application transmitted a series of erroneous notifications, including claims of nuclear and chemical hazards and the deployment of Russia’s hypersonic Oreshnik missile, according to Al Jazeera. The alerts were said to have originated after the app was allegedly compromised by Russian actors.
The Ukrainian Air Force posted on Telegram indicating that the map‑based warning system had been “subjected to enemy influence” and that there was no radiation threat, urging civilians to remain calm and follow official updates.
A short statement from SPRAVDI, Ukraine’s Centre for Strategic Communications, was posted on X, explicitly blaming Russia for the hacking incident.
Russian emergency services, on the other hand, confirmed on Telegram early Monday that a “massive cyberattack” had struck their mobile applications, resulting in the dissemination of false information, yet the ministry denied that it had orchestrated the spread.
The article notes that Al Jazeera is the sole outlet that reports the specific claim of a hypersonic Oreshnik missile deployment in the false alerts, a detail not cited elsewhere.
