Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Synology breach identified under incident ID SYN1774513446.
The analysis begins with a detailed overview of Synology's information like the linkedin page: https://www.linkedin.com/company/synology, the number of followers: 34649, the industry type: IT Services and IT Consulting and the number of employees: 986 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 730 and after the incident was 726 with a difference of -4 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 Synology and their customers.
Synology recently reported "Synology Patches Critical Remote Code Execution Flaw in DSM Software", a noteworthy cybersecurity incident.
Synology has released an urgent security update for its DiskStation Manager (DSM) software to address a critical vulnerability (CVE-2026-32746) that could allow unauthenticated remote attackers to execute arbitrary commands on affected network-attached storage (NAS) devices.
The disruption is felt across the environment, affecting Network-attached storage (NAS) devices, and exposing Sensitive business backups and personal data.
In response, moved swiftly to contain the threat with measures like Disable the Telnet service via Control Panel’s Terminal settings, and began remediation that includes Apply security patches for DSM versions 7.3, 7.2.2, and 7.2.1; replace Telnet with SSH.
The case underscores how and recommending next steps like Disable Telnet service, apply security patches, replace Telnet with encrypted alternatives like SSH.
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%), with evidence including buffer overflow defect in the telnetd service, and unauthenticated remote attackers to execute arbitrary commands. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (80%), with evidence including execute arbitrary commands on affected NAS devices, and remote code execution without authentication. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), with evidence including buffer overflow defect (CWE-120) in telnetd service, and out-of-bounds write enabling remote code execution. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (70%), with evidence including potential ransomware deployment, and data encryption such as Potential and Resource Hijacking (T1496) with moderate confidence (60%), with evidence including lateral movement within internal networks, and nAS devices often store sensitive business backups. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), with evidence including data theft, and data exfiltration such as Potential. Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (80%), with evidence including lateral movement within internal networks, and remote code execution on NAS devices. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
