Google Cloud Security Breach Incident Score: Analysis & Impact (GOO0402404111925)

In this Rankiteo incident briefing, we review the Google Cloud Security breach identified under incident ID GOO0402404111925.

The analysis begins with a detailed overview of Google Cloud Security's information like the linkedin page: https://www.linkedin.com/company/googlecloudsecurity, the number of followers: 50322, the industry type: Computer and Network Security and the number of employees: 464 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 551 and after the incident was 546 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 Google Cloud Security and their customers.

Google recently reported "Google Chrome Zero-Day Vulnerability (CVE-2025-13223) in V8 JavaScript Engine", a noteworthy cybersecurity incident.

For the third time in recent months, Google has addressed a potentially serious zero-day flaw in the Chrome browser’s V8 JavaScript engine.

The disruption is felt across the environment, affecting Google Chrome browser (V8 JavaScript engine).

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Emergency 'out-of-band' patch, and began remediation that includes Patch for CVE-2025-13223.

The case underscores how Ongoing (evidence of exploitation in the wild confirmed).

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%), supported by evidence indicating zero-day vulnerability (CVE-2025-13223) in Chrome’s V8 JavaScript engine exploited in the wild. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: JavaScript (T1059.001) with high confidence (90%), supported by evidence indicating flaw in V8 JavaScript engine... allowing attackers to execute arbitrary code. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (85%), supported by evidence indicating potentially allowing attackers to... escalate privileges on affected systems. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (75%), supported by evidence indicating zero-day exploit in V8 engine (commonly leveraged for obfuscated payload delivery). Under the Impact tactic, the analysis identified Resource Hijacking (T1496) with moderate to high confidence (80%), supported by evidence indicating compromise user data or escalate privileges (implies system resource abuse). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
