Ukraine's air force says its emergency alert system was hacked hours after a truce ended, causing false alerts of nuclear threats and chemical attacks in Kyiv. The system, which is used to warn of incoming drones or missiles, was temporarily taken offline after being compromised.
The cyberattack occurred as the longest truce of the war, limited to Ukraine's eastern Kherson region, ended on November 1, 2026. The system was reportedly infiltrated by unauthorized parties, leading to a series of false alerts that confused residents and prompted urgent public statements from Ukrainian authorities.
Ukrainian officials confirmed the breach, stating there was no actual radiation threat and urging caution. The incident highlights the growing concern over cyber threats in the context of the ongoing conflict, with officials warning of potential disruptions to critical infrastructure.
The attack comes as Europe faces a new wave of cyber incidents, including freezer tampering in supermarkets across Ireland, Estonia, Sweden, Belgium, and Luxembourg, suggesting a broader pattern of cyber threats targeting both military and civilian infrastructure.
