Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the IRON Cluster breach identified under incident ID IRO1782289540.
The analysis begins with a detailed overview of IRON Cluster's information like the linkedin page: https://www.linkedin.com/company/iron-cluster, the number of followers: 3401, the industry type: Technology, Information and Media and the number of employees: 10 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 752 and after the incident was 732 with a difference of -20 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 IRON Cluster and their customers.
On 06 June 2026, Besomar disclosed Cyberespionage issues under the banner "GhostShell Espionage Campaign Targets Ukraine’s UAV Sector with RAR Exploit".
A newly uncovered cyberespionage campaign, attributed to an emerging threat actor dubbed *GhostShell*, is targeting Ukraine’s unmanned aerial vehicle (UAV) ecosystem.
The disruption is felt across the environment, affecting Windows systems with Startup folder persistence.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing.
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.
MITRE ATT&CK® Correlation Analysis
Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Phishing: Spearphishing Attachment (T1566.001) with high confidence (90%), supported by evidence indicating malicious RAR archive *Besomar_documentation.rar* containing decoy PDFs and Exploit Public-Facing Application (T1190) with moderate to high confidence (80%), supported by evidence indicating exploits two vulnerabilities, CVE-2025-8088 and CVE-2025-6218.
