In this Rankiteo incident briefing, we review the ASUS breach identified under incident ID ASU1766433512.

The analysis begins with a detailed overview of ASUS's information like the linkedin page: https://www.linkedin.com/company/asus, the number of followers: 987332, the industry type: Computer Hardware Manufacturing and the number of employees: 16061 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 679 and after the incident was 674 with a difference of -5 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 ASUS and their customers.

ASUS recently reported "ASUS Live Update Supply-Chain Attack (CVE-2025-59374)", a noteworthy cybersecurity incident.

A supply-chain attack on the ASUS Live Update utility where attackers exploited its distribution network to embed malicious code via updates considered legitimate.

Impact assessments are still underway, so the full scope is not yet clear.

In response, and began remediation that includes Software product phased out and retired.

The case underscores how teams are taking away lessons such as Importance of understanding historical vulnerabilities to evaluate past security assessments and the risks of trusted channels in supply-chain attacks. Emphasis on routine software audits and diligence regarding manufacturer updates for robust cybersecurity practices, and recommending next steps like Organizations and users should focus on legitimate vulnerability reports and updates concerning currently utilized systems to manage and protect against actual threats.

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.

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 Supply Chain Compromise: Compromise Software Supply Chain (T1195.002) with high confidence (95%), with evidence including malicious code embedded in legitimate updates, and exploitation of trusted update mechanisms. Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with moderate to high confidence (85%), supported by evidence indicating malicious code embedded in legitimate updates via trusted distribution network. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
