Russia and Ukraine have reported cyberattacks on their emergency warning applications after users received false alerts about potential threats, raising concerns over the reliability of public safety notifications during the ongoing war.

Ukraine’s Air Force confirmed on Sunday, November 1, that its air raid warning application had been compromised after false notifications appeared in Kyiv and other parts of the country.

The alerts incorrectly warned of nuclear and chemical threats, street fighting and the deployment of Russia’s Oreshnik hypersonic missile.

Ukrainian authorities urged residents to remain calm, stressing that the reported radiation danger was not real.

Hours later, Russia’s Ministry of Emergency Situations reported a separate cyberattack on its mobile application, saying unauthorized users had been able to distribute false emergency information.

False alerts disrupt Ukraine’s warning system

Ukraine’s air raid application is widely used to notify residents of incoming missiles, drones and other threats, often giving people only a short time to reach shelter.

The false warnings appeared late Sunday, prompting authorities to clarify that the notifications did not reflect actual conditions.

Ukraine’s Centre for Countering Disinformation advised the public to rely on verified government updates rather than the affected application.

The Ministry of Digital Transformation confirmed that the app had been disrupted but said other emergency notification channels, including air raid sirens, remained operational.

Kyiv authorities also reported that a separate warning application serving the capital was functioning normally.

The false notifications were subsequently removed, although the incident prompted temporary restrictions on some app functions while technical teams worked to restore reliable alerts.

Russia reports separate cyberattack

Early Monday, November 2, Russia’s Ministry of Emergency Situations said its mobile warning application had also been targeted.

The ministry described the incident as a large-scale cyberattack that allowed false information to reach users.

The Russian application provides notifications about emergencies, including drone attacks and other potential dangers.

Authorities said technical personnel were working to restore the affected service.

Neither government had publicly established who was responsible for both incidents, and there was no confirmation that the attacks were connected.

Incidents follow end of Kherson ceasefire

The disruptions occurred around the end of a temporary ceasefire in Ukraine’s southern Kherson region.

The localized truce began on October 27 and expired on Sunday, November 1. It had allowed civilians to leave areas affected by fighting.

Ukraine reported evacuating 167 people from parts of Kherson on Sunday, while local officials urged residents to remain alert as the ceasefire ended.

The timing of the false warnings raised concerns about public safety, particularly in communities where residents depend on accurate alerts to respond to genuine attacks.

Ukrainian officials have accused Russia of interfering with the country’s warning system. However, that allegation has not been independently established, and Moscow has not publicly identified those responsible for the attack on its own application.

The incidents underscore the vulnerability of digital emergency services during wartime, when false notifications can create confusion and interruptions may affect access to potentially life-saving warnings.
