Meta Breach Incident Score: Analysis & Impact (MET1764979506)

In this Rankiteo incident briefing, we review the Meta breach identified under incident ID MET1764979506.

The analysis begins with a detailed overview of Meta's information like the linkedin page: https://www.linkedin.com/company/instagram, the number of followers: 11513481, the industry type: Software Development and the number of employees: 140153 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 801 and after the incident was 801 with a difference of 0 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 Meta and their customers.

On 08 January 2025, Meta (React Server Components) disclosed Remote Code Execution (RCE) issues under the banner "React2Shell Vulnerability Exploitation".

Critical vulnerabilities in Meta’s React Server Components and Next.js are under threat from botnets and state-linked adversaries.

The disruption is felt across the environment, affecting React Server Components, Next.js frameworks.

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 Exploit Public-Facing Application (T1190) with high confidence (95%), with evidence including enables unauthenticated attacker to achieve remote code execution, and exploitation of CVE-2025-55182 (React2Shell). Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with high confidence (90%), with evidence including remote code execution due to unsafe deserialization of payloads, and abusing trust in incoming data structures and Command and Scripting Interpreter (T1059) with moderate to high confidence (80%), supported by evidence indicating potential unauthorized remote code execution on affected servers. Under the Persistence tactic, the analysis identified Server Software Component: Web Shell (T1505.003) with moderate to high confidence (70%), supported by evidence indicating react2Shell added to Mirai and other botnet exploitation kits. Under the Impact tactic, the analysis identified Resource Hijacking (T1496) with moderate to high confidence (80%), with evidence including botnet integration, and mirai botnet exploitation kits. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate confidence (60%), with evidence including potential data exfiltration, and state-linked adversaries motivation. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
