Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the GuidePoint Security breach identified under incident ID CITGUIKONARC1783031139.
The analysis begins with a detailed overview of GuidePoint Security's information like the linkedin page: https://www.linkedin.com/company/guidepointsec, the number of followers: 60399, the industry type: IT Services and IT Consulting and the number of employees: 1321 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 759 and after the incident was 757 with a difference of -2 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 GuidePoint Security and their customers.
A newly reported cybersecurity incident, "Anubis Ransomware Exploits Citrix Bleed 2 in Targeted Attacks Across Critical Sectors", has drawn attention.
Threat actors linked to the Anubis ransomware-as-a-service (RaaS) operation are actively exploiting CVE-2025-5777 (Citrix Bleed 2), a critical vulnerability in Citrix NetScaler ADC and Gateway, to gain initial access to victim networks.
The disruption is felt across the environment, affecting Citrix NetScaler ADC and Gateway, VPN systems (Cisco AnyConnect) and Windows systems, and exposing True.
Formal response steps have not been shared publicly yet.
Overall, the incident is a reminder of why proactive monitoring and strong governance matter.
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.
