Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the TrueConf breach identified under incident ID F5TRU1775587606.

The analysis begins with a detailed overview of TrueConf's information like the linkedin page: https://www.linkedin.com/company/trueconf, the number of followers: 5000, the industry type: Software Development and the number of employees: 105 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 752 and after the incident was 749 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 TrueConf and their customers.

TrueConf recently reported "CISA Adds TrueConf Client Flaw to Known Exploited Vulnerabilities Catalog", a noteworthy cybersecurity incident.

The U.S.

The disruption is felt across the environment, affecting TrueConf Client.

In response, moved swiftly to contain the threat with measures like Patch application or mitigations recommended, and began remediation that includes Apply available patches.

The case underscores how Ongoing, teams are taking away lessons such as Organizations must prioritize vulnerability remediation and monitor advisories from authorities like CISA, and recommending next steps like Apply patches for TrueConf Client immediately and monitor systems for signs of exploitation, with advisories going out to stakeholders covering CISA urges organizations to apply patches or mitigations for TrueConf Client.

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 vulnerability in TrueConf Client added to CISA KEV catalog, and active exploitation risks signaled. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), with evidence including trueConf Client flaw exploited for unauthorized access, and urgency to apply patches or mitigations. Under the Persistence tactic, the analysis identified External Remote Services (T1133) with moderate confidence (60%), supported by evidence indicating potential unauthorized access to systems using TrueConf Client. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating exploitation of software vulnerability may involve valid accounts. Under the Impact tactic, the analysis identified Endpoint Denial of Service (T1499) with lower confidence (40%), supported by evidence indicating potential operational impact due to unauthorized access. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
