Cyberattacks Target Russian, and Ukrainian Alert Systems as Kherson Truce Expires
Russia and Ukraine reported cyberattacks on their public warning systems Monday, raising concerns about the reliability of emergency alerts as a temporary ceasefire in the war expired.
Russia’s Emergency Situations Ministry said its public warning application had suffered a “massive cyberattack,” allowing hackers to distribute false information. The ministry said technical teams were working to restore the service but did not identify those responsible.
The announcement came hours after Ukraine reported a suspected breach of its Air Alarm application, which delivers alerts about incoming attacks. The platform issued false warnings about a radiation threat, prompting Ukraine’s air force to reassure residents that no such danger existed.
Air force spokesman Yuriy Ignat confirmed to AFP that the application had been compromised. Ukraine’s Center for Strategic Communications, known as SPRAVDI, blamed Russia for the incident.
The cyber incidents coincided with the end of a temporary ceasefire in Ukraine’s southern Kherson region. The truce, which ran from Oct. 27 through Nov. 1, was the longest pause in fighting since Russia launched its full-scale invasion in February 2022.
Ukraine’s human rights commissioner, Dmytro Lubinets, described the arrangement as an important humanitarian initiative. The pause had allowed a humanitarian mission to reach Oleshky, a Russian-occupied city in the Kherson region.
Kherson Gov. Oleksandr Prokudin urged residents to remain alert and respond promptly to warnings of possible Russian attacks after the ceasefire expired.
A Ukrainian military officer, speaking to AFP on condition of anonymity, warned that hostilities could intensify. The officer alleged that Russian forces had used the pause to reinforce positions, move ammunition and conduct surveillance with drones.
Russia declined Kyiv’s offer to extend the ceasefire, according to Ukrainian officials.
The diplomatic effort came as prospects for renewed negotiations remained uncertain. U.S.-mediated talks between Moscow and Kyiv are expected to resume this month after stalling in February.
Ukrainian President Volodymyr Zelensky said Sunday that Kyiv could halt strikes on Russian oil refineries if Washington supplied Ukraine with additional Patriot air defense missiles.
Speaking to Fox News, Zelensky said Ukraine expected Russia to stop attacking its energy infrastructure if Kyiv suspended operations against Russian refineries. He presented the supply of Patriot interceptors as an alternative.
U.S. President Donald Trump has urged Ukraine to stop targeting Russian oil facilities, citing concerns about rising diesel prices. Analysts have linked the increase to the war involving Iran.
Meanwhile, both countries reported further attacks over the weekend.
Russian officials said a drone struck an industrial facility east of Moscow. Ukrainian media reported that the target was the Kstovo oil refinery, although Moscow did not independently confirm the facility’s identity.
Ukraine has repeatedly targeted Russian oil and gas infrastructure, describing the operations as retaliation for Russian attacks on its energy network.
Ukraine’s Energy Ministry reported fresh power outages Sunday, including in Kyiv, following Russian strikes on energy facilities.
The wider conflict has devastated communities across eastern and southern Ukraine, killed and wounded large numbers of military personnel and civilians, and displaced millions since Russia’s invasion began in 2022.
