Cyber Incident Victim: Armed Forces of Ukraine
Date:
Jan 2022
Location:
Ukraine
Summary
Multiple Ukrainian government websites were compromised and defaced through exploitation of a critical authentication vulnerability in outdated content management software, leading to false claims of data compromise which authorities denied. The attack affected public institutions including ministries of foreign affairs, defense, and education, displaying multilingual messages with grammatical errors suggesting potential foreign involvement. While restoration efforts were ongoing, Polish military databases were also breached in a possibly related incident. Ukrainian investigators linked the intrusion to a known software flaw but did not attribute responsibility, though cybersecurity researchers suspected involvement of a Belarus-linked threat group amid regional geopolitical tensions.

Description
On January 14, 2022, multiple Ukrainian government websites were compromised and defaced, affecting at least 15 public institutions. The targeted entities included the ministry of foreign affairs, ministry of agriculture, ministry of education and science, ministry of security and defense, and the online portal for the cabinet of ministers. Attackers replaced website content with messages in Ukrainian, Russian, and Polish falsely claiming that all citizen data uploaded to the public network had been compromised. Ukrainian cyber-police immediately refuted these claims, confirming no personal data was breached. Authorities took affected websites offline as IT specialists began restoration efforts, with some remaining inaccessible during recovery. The defacement coincided with heightened Ukraine-Russia geopolitical tensions, though no explicit motive was declared.
Technical analysis revealed attackers exploited CVE-2021-32648, a critical authentication bypass vulnerability in outdated October CMS software that enabled unauthorized password resets. Polish Ministry of National Defense separately reported breaches of military databases, suggesting potential coordination with the Ukrainian incident. Linguistic analysis of defacement messages noted grammatical errors consistent with machine translation tools like Yandex, raising suspicions of Russian involvement. Ukrainian cyber-police arrested a ransomware gang in an unrelated operation during this period but did not attribute the defacements to any group. Researchers cited potential links to the GhostWriter APT group, historically associated with Belarusian interests. Ukrainian authorities emphasized ongoing investigations while continuing system restoration and vulnerability remediation efforts across affected agencies.
