Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Synacor breach identified under incident ID SYN1778473638.
The analysis begins with a detailed overview of Synacor's information like the linkedin page: https://www.linkedin.com/company/synacor, the number of followers: 10975, the industry type: Software Development and the number of employees: 182 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 753 and after the incident was 750 with a difference of -3 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 Synacor and their customers.
A newly reported cybersecurity incident, "New Rust-Based 01flip Ransomware Targets Critical Infrastructure in Asia-Pacific", has drawn attention.
Researchers from Palo Alto Networks’ Unit 42 uncovered 01flip, a sophisticated Rust-based ransomware strain actively targeting Windows and Linux systems in coordinated attacks on critical infrastructure across the Asia-Pacific region, particularly in Southeast Asia.
The disruption is felt across the environment, affecting Windows and Linux systems.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing, teams are taking away lessons such as The 01flip campaign highlights the need for zero-trust principles, cross-platform defenses, and strengthened visibility, patching, and detection across all environments, and recommending next steps like Strengthen visibility and detection across Windows and Linux systems, Implement zero-trust principles to limit lateral movement and Patch vulnerabilities in internet-facing applications promptly.
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 exploiting vulnerabilities in outdated, internet-facing applications (e.g., Zimbra Server). Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating deployed the Linux variant of the Sliver post-exploitation framework and Command and Scripting Interpreter (T1059) with moderate to high confidence (70%), supported by evidence indicating hands-on-keyboard operations rather than automated attacks. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating harvest credentials, and map the network. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), supported by evidence indicating sliver post-exploitation framework to conduct reconnaissance. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with high confidence (90%), supported by evidence indicating rust’s low-level API calls, runtime string decoding, and anti-sandbox checks and Masquerading (T1036) with moderate to high confidence (80%), supported by evidence indicating linux variant remained undetected on VirusTotal for nearly three months. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (70%), supported by evidence indicating harvest credentials, and map the network. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (80%), supported by evidence indicating systematic drive enumeration (A-Z) and ransom note deployment and Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating map the network indicating hands-on-keyboard operations. Under the Lateral Movement tactic, the analysis identified Remote Services (T1021) with moderate to high confidence (80%), supported by evidence indicating manually distributing 01flip ransomware binaries across both Windows and Linux systems. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), supported by evidence indicating aES-128-CBC encryption with RSA-2048-protected session keys and Service Stop (T1489) with moderate to high confidence (70%), supported by evidence indicating disruption of critical infrastructure operations. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
