Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the CERT-UA breach identified under incident ID CER1775061546.
The analysis begins with a detailed overview of CERT-UA's information like the linkedin page: https://www.linkedin.com/company/cert-ua, the number of followers: 1836, the industry type: Computer and Network Security and the number of employees: 23 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 689 and after the incident was 668 with a difference of -21 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on CERT-UA and their customers.
On 26 March 2026, State organizations disclosed Phishing Campaign issues under the banner "Ukrainian CERT-UA Targeted in Phishing Campaign Distributing AGEWHEEZE Malware".
The Computer Emergency Response Team of Ukraine (CERT-UA) uncovered a sophisticated phishing campaign in which threat actors impersonated the agency to distribute the AGEWHEEZE remote administration trojan.
The disruption is felt across the environment, affecting Personal devices of employees (primarily educational institutions), and exposing Potential access to sensitive data (e.g., client databases, source code).
In response, teams activated the incident response plan, and began remediation that includes Remediation support provided to affected parties.
The case underscores how Ongoing, teams are taking away lessons such as Need for heightened awareness of phishing campaigns impersonating official agencies; importance of verifying sender domains and avoiding password-protected archives from untrusted sources, and recommending next steps like Implement multi-factor authentication (MFA) for email accounts, Educate employees on phishing risks and domain spoofing and Monitor for unusual WebSocket traffic to unknown IPs, with advisories going out to stakeholders covering CERT-UA issued advisories to targeted sectors; Cipher confirmed limited impact of the February 2026 breach.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
