Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the Google breach identified under incident ID GOO1768856368.

The analysis begins with a detailed overview of Google's information like the linkedin page: https://www.linkedin.com/company/google, the number of followers: 40050213, the industry type: Software Development and the number of employees: 327709 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 498 and after the incident was 497 with a difference of -1 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 and their customers.

Google recently reported "Google Gemini Flaw Exposed Private Calendar Data via Indirect Prompt Injection", a noteworthy cybersecurity incident.

Cybersecurity researchers at Miggo Security uncovered a critical vulnerability in Google Gemini that allowed attackers to bypass authorization controls and exfiltrate private meeting data through Google Calendar.

The disruption is felt across the environment, affecting Google Gemini, Google Calendar, and exposing Private meeting data.

In response, moved swiftly to contain the threat with measures like Patch issued by Google, and began remediation that includes Vulnerability patched.

The case underscores how Resolved (patched by Google), teams are taking away lessons such as The incident highlights the expanding attack surface of AI-native features, particularly in prompt injection, privilege escalation, and agentic behavior. It underscores the need for rigorous testing and oversight in enterprise AI deployments, and recommending next steps like Implement rigorous testing and oversight for AI systems, particularly focusing on prompt injection, privilege escalation, and agentic behavior vulnerabilities.

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 Phishing: Spearphishing Link (T1566.002) with moderate to high confidence (80%), supported by evidence indicating crafted event invite containing a hidden prompt in its description. Under the Execution tactic, the analysis identified User Execution: Malicious Link (T1204.001) with moderate to high confidence (70%), supported by evidence indicating user asked Gemini an innocuous question, triggering malicious prompt. Under the Privilege Escalation tactic, the analysis identified Abuse Elevation Control Mechanism: Bypass User Account Control (T1548.002) with moderate confidence (60%), supported by evidence indicating bypass authorization controls and exfiltrate private meeting data. Under the Defense Evasion tactic, the analysis identified Masquerading: Match Legitimate Name or Location (T1036.005) with moderate to high confidence (80%), supported by evidence indicating seemingly harmless calendar invite with hidden malicious prompt and Indirect Command Execution (T1202) with high confidence (90%), supported by evidence indicating indirect prompt injection embedding malicious instructions. Under the Collection tactic, the analysis identified Data from Information Repositories: Code Repositories (T1213.003) with moderate to high confidence (70%), supported by evidence indicating summarizing all private meetings and embedding the data and Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating private meeting data was exfiltrated via Google Calendar. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating data embedded into a new calendar event visible to the attacker and Transfer Data to Cloud Account (T1537) with moderate confidence (60%), supported by evidence indicating exfiltrate private meeting data through Google Calendar. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
