Kyiv:Moscow Russia and Ukraine have reported simultaneous cyberattacks on their emergency warning apps following the conclusion of a temporary ceasefire in Oleshky on Sunday.

According to Anadolu Agency – English, the first reports emerged from Kyiv late Sunday, where the Ukrainian Air Force indicated that the public air raid app had "likely been compromised" by Russia. Ukraine's Center for Strategic Communications accused Russia of hacking the app, citing "several unusual alerts" and the use of the Russian language in one of the messages. The air raid alert channel in Ukraine mentioned that "unauthorized parties" interfered with the app's operation, leading to a temporary suspension while additional security measures are implemented.

Shortly thereafter, the Russian Emergency Situations Ministry announced that its mobile app also suffered a "massive" cyberattack, which enabled perpetrators to distribute false information to the public. The attack reportedly occurred at approximately 245 am Moscow time on Monday, affecting 33 regions within Russia. Specialists analyzed the incident, identified vulnerabilities, and the findings were forwarded to the National Coordination Center for Computer Incidents. Efforts are underway to prevent future incidents and restore normal operations.

The six-day truce in the Russian-controlled city of Oleshky, located in Ukraine's southern Kherson region, ended at 2100GMT on November 1. The ceasefire had been brokered by U.S. First Lady Melania Trump. So far, no party has claimed responsibility for the cyberattacks.
