Computer Emergency Response Team of Ukraine

CERT-UA, also known as the Computer Emergency Response Team of Ukraine, is the national agency responsible for coordinating cybersecurity incident response across the country. Its core functions include detecting, analysing, and mitigating cyber threats, issuing alerts and advisories, and providing technical assistance to government bodies, critical infrastructure operators, and private organisations. By collecting and sharing indicators of compromise, CERT-UA helps stakeholders defend against malware, phishing, and other attack vectors. The team monitors threat activity and supports timely response actions to protect Ukrainian networks.

In its role as Ukraine’s authoritative point of contact for cybersecurity events, CERT-UA collaborates with domestic law‑enforcement agencies, international CERTs, and private‑sector security firms to exchange threat intelligence and best practices. The organisation publishes detailed reports on significant campaigns, such as the IcedID malware distribution via malicious Excel documents in April 2022 and the Russian‑linked spear‑phishing operation observed in June 2021. These publications outline the tactics, techniques, and procedures used by threat actors and offer guidance on detection and remediation. Through such outreach, CERT-UA contributes to raising the overall cyber resilience of Ukrainian entities.

Distinguishing attributes of CERT-UA include its proven ability to attribute cyber‑espionage activities to specific threat clusters, exemplified by its attribution of the April 2022 incident to UAC‑0041 and UAC‑0097 and its linkage of the June 2021 campaign to Russian‑linked actors. The team possesses specialised capabilities in malware reverse‑engineering, vulnerability assessment, and email‑system exploit analysis, as demonstrated by its handling of the Zimbra vulnerability used for unauthorized email forwarding. Its regulatory position as part of Ukraine’s state cybersecurity framework enables it to issue binding recommendations and to coordinate national‑level response measures.

Structurally, CERT-UA operates as a governmental body within Ukraine’s national cybersecurity structure, reporting to the state authority responsible for communications and information protection. It does not have a private‑sector parent or subsidiary arrangement; instead, it functions as a public service unit funded through the state budget. This arrangement allows CERT-UA to serve as the central coordination hub for cybersecurity incidents affecting both public and private sectors while maintaining accountability to governmental oversight.
