ASUS Breach Incident Score: Analysis & Impact (ASU1764705548)

In this Rankiteo incident briefing, we review the ASUS breach identified under incident ID ASU1764705548.

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 769 and after the incident was 680 with a difference of -89 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 "Everest Ransomware Group Claims ASUS Breach", a noteworthy cybersecurity incident.

A new claim by the Everest ransomware group suggests that ASUS, one of the world’s largest hardware and electronics companies, has been compromised.

The disruption is felt across the environment, and exposing 1TB of data, including camera source code.

Formal response steps have not been shared publicly yet.

The case underscores how Ongoing.

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 Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating everest ransomware group claims full network access in past incidents and Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating no specific attack vector disclosed, but common in ransomware incidents. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with high confidence (90%), supported by evidence indicating 1TB of data stolen, including camera source code and Transfer Data to Cloud Account (T1537) with moderate confidence (60%), supported by evidence indicating ransomware groups often exfiltrate data to attacker-controlled cloud storage. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (80%), supported by evidence indicating incident type explicitly labeled as Ransomware and Inhibit System Recovery (T1490) with moderate to high confidence (70%), supported by evidence indicating common ransomware tactic to prevent restoration of systems. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating common precursor to ransomware attacks for initial access and Unsecured Credentials: Credentials In Files (T1552.001) with moderate confidence (50%), supported by evidence indicating possible method for gaining valid accounts in ASUS environment. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
