Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the BlackFog breach identified under incident ID BLA1767165685.
The analysis begins with a detailed overview of BlackFog's information like the linkedin page: https://www.linkedin.com/company/blackfog, the number of followers: 4241, the industry type: Software Development and the number of employees: 29 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 750 and after the incident was 636 with a difference of -114 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 BlackFog and their customers.
A newly reported cybersecurity incident, "Fog Ransomware Attack on Asian Financial Institution", has drawn attention.
A cyberattack on a financial institution in Asia featuring the Fog ransomware involved unusual tools and tactics, including legitimate employee monitoring software (Syteca) and open-source pentesting tools (GC2).
The disruption is felt across the environment, affecting Microsoft Exchange servers, and exposing True.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing, teams are taking away lessons such as Unusual tools (e.g., Syteca, GC2) and post-ransomware persistence suggest potential espionage motives. Legitimate software can be abused for malicious purposes, and attackers may use ransomware as a decoy, and recommending next steps like Monitor and restrict the use of legitimate employee monitoring tools like Syteca to prevent abuse, Patch and secure Microsoft Exchange servers to mitigate common entry points and Enhance detection capabilities for open-source pentesting tools (e.g., GC2) used in attacks.
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 Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating microsoft Exchange servers (likely exploiting longstanding vulnerabilities). Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (80%), supported by evidence indicating gC2 tool leveraging Google Sheets, Microsoft SharePoint for command execution and User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating use of open-source pentesting tools (GC2) for command execution. Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate to high confidence (70%), supported by evidence indicating attackers established persistence after deploying ransomware and Event Triggered Execution (T1546) with moderate confidence (60%), supported by evidence indicating use of legitimate employee monitoring software (Syteca) for persistence. Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with high confidence (90%), supported by evidence indicating use of legitimate employee monitoring software (Syteca) for malicious purposes and Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating abuse of legitimate tools (Syteca, GC2) suggests valid account compromise. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (60%), supported by evidence indicating microsoft Exchange servers exploited; likely credential harvesting. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating attack lasted 2 weeks; likely internal reconnaissance. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating gC2 used for data exfiltration via cloud storage. Under the Command and Control tactic, the analysis identified Ingress Tool Transfer (T1105) with moderate to high confidence (80%), supported by evidence indicating gC2 tool leveraging Google Sheets/SharePoint for C2. Under the Exfiltration tactic, the analysis identified Transfer Data to Cloud Account (T1537) with high confidence (90%), supported by evidence indicating gC2 used for data exfiltration via cloud storage and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating data exfiltration confirmed; GC2 used for command execution. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), supported by evidence indicating fog ransomware deployed; data encryption confirmed. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
