Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the KILLASOFT breach identified under incident ID CYDKIL1770303400.
The analysis begins with a detailed overview of KILLASOFT's information like the linkedin page: https://www.linkedin.com/company/killasoft, the number of followers: 24, the industry type: Computer Games and the number of employees: 5 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 755 and after the incident was 644 with a difference of -111 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 KILLASOFT and their customers.
A newly reported cybersecurity incident, "ShadowSyndicate Adopts Advanced SSH Key Rotation to Evade Detection", has drawn attention.
The cybercriminal group ShadowSyndicate has refined its infrastructure management tactics by rotating SSH keys across multiple servers to obscure its operations and complicate tracking efforts.
Impact assessments are still underway, so the full scope is not yet clear.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as ShadowSyndicate's evolving tactics, such as SSH key rotation and infrastructure reuse, underscore the need for continuous infrastructure correlation and proactive detection to counter adaptive evasion strategies, and recommending next steps like Security teams should monitor for repeated MFA failures, high-volume login attempts, rapid valid credential usage, and geographic mismatches between login attempts and device locations. Additionally, track specific autonomous system numbers (ASNs) associated with the group's hosting providers.
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 Valid Accounts (T1078) with moderate to high confidence (80%), with evidence including rapid valid credential usage, and high-volume login attempts and Trusted Relationship (T1199) with moderate to high confidence (70%), supported by evidence indicating shadowSyndicate may function as an Initial Access Broker (IAB). Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate to high confidence (80%), supported by evidence indicating sSH key rotation across multiple servers to maintain access and Create Account (T1136) with moderate confidence (60%), supported by evidence indicating use of diverse attack frameworks for persistent network access. Under the Defense Evasion tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating sSH key rotation to obscure operations and complicate tracking, Use Alternate Authentication Material: SSH Keys (T1550.004) with high confidence (90%), supported by evidence indicating cycling SSH keys in ways that mimic legitimate server transfers, and Obfuscated Files or Information (T1027) with moderate to high confidence (70%), supported by evidence indicating reusing servers and cycling SSH keys to evade detection. Under the Command and Control tactic, the analysis identified Application Layer Protocol (T1071) with high confidence (90%), supported by evidence indicating 20 command-and-control (C2) servers supporting Cobalt Strike, MetaSploit, etc. and Encrypted Channel (T1573) with moderate to high confidence (80%), supported by evidence indicating sSH key rotation and use of C2 frameworks for encrypted communication. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate to high confidence (80%), supported by evidence indicating high-volume login attempts, repeated MFA failures and Unsecured Credentials: Private Keys (T1552.004) with moderate to high confidence (70%), supported by evidence indicating sSH key rotation and reuse across servers. Under the Lateral Movement tactic, the analysis identified Remote Services: SSH (T1021.004) with moderate to high confidence (80%), supported by evidence indicating sSH key rotation for lateral movement across servers. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating c2 servers supporting ransomware operations like Black Basta. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ransomware strains such as Cl0p, ALPHV/BlackCat, Black Basta, Ryuk. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
