Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the CodeRabbit breach identified under incident ID CODGIT1783765479.
The analysis begins with a detailed overview of CodeRabbit's information like the linkedin page: https://www.linkedin.com/company/coderabbitai, the number of followers: 36161, the industry type: Software Development and the number of employees: 251 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 754 and after the incident was 736 with a difference of -18 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 CodeRabbit and their customers.
Public repositories using AI code reviewers recently reported "Ghostcommit: AI Code Reviewers Tricked into Stealing Secrets via Malicious PNGs", a noteworthy cybersecurity incident.
Researchers demonstrated a novel attack, Ghostcommit, that exploits AI code reviewers to exfiltrate repository secrets by embedding malicious instructions in PNG files.
The disruption is felt across the environment, affecting AI code review tools (e.g., CodeRabbit, Cursor, Antigravity, Claude Code), and exposing Repository secrets (.env files).
In response, moved swiftly to contain the threat with measures like Development of a multimodal pull-request defender GitHub app to scan for invisible characters, analyze code structure, and review image files using an LLM, and began remediation that includes Advocacy for runtime monitoring to detect agents accessing sensitive files without justification, and stakeholders are being briefed through Disclosure to affected vendors.
The case underscores how Proof-of-concept demonstrated, disclosed to affected vendors, teams are taking away lessons such as AI code review tools must incorporate multimodal analysis to detect malicious payloads in non-text files. Structural blind spots in tooling configurations can lead to significant security risks, and recommending next steps like Implement multimodal pull-request defenders to scan image files and code structure, Enable runtime monitoring to detect unauthorized access to sensitive files and Review and update AI tool configurations to include image file analysis.
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 Supply Chain Compromise: Compromise Software Dependencies and Development Tools (T1195.002) with high confidence (90%), with evidence including exploits AI code reviewers to exfiltrate repository secrets, and targets a critical gap in automated review processes and Phishing: Spearphishing Attachment (T1566.001) with moderate to high confidence (80%), with evidence including malicious instructions in seemingly innocuous PNG files, and pNG referenced in AGENTS.md parsed as project policy. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: Unix Shell (T1059.002) with moderate to high confidence (70%), supported by evidence indicating aI agent reads PNG, extracts .env contents, embeds as integers in output code and User Execution: Malicious File (T1204.002) with moderate to high confidence (80%), supported by evidence indicating developers request routine tasks, triggering AI to follow AGENTS.md directives. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with high confidence (95%), with evidence including read the repository’s .env file, and encode its contents as a list of integers. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), with evidence including read the repository’s .env file, and entire .env file encoded into 311 integers. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), with evidence including secrets embedded in generated module as a provenance constant, and decoded by attackers from the public commit and Exfiltration Over Web Service: Exfiltration to Code Repository (T1567.002) with high confidence (90%), with evidence including exfiltrate repository secrets via public commit, and encoded as integers in output code. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information: Command Obfuscation (T1027.010) with moderate to high confidence (80%), with evidence including encode .env contents as a list of integers, and secret scanners failed to detect exfiltration and Hide Artifacts: Hidden Files and Directories (T1564.001) with high confidence (90%), with evidence including malicious payload in an image file referenced in AGENTS.md, and aI reviewers exclude image files from analysis. Under the Lateral Movement tactic, the analysis identified Software Deployment Tools (T1072) with moderate to high confidence (70%), supported by evidence indicating aI code reviewers (e.g., CodeRabbit, Cursor) used to propagate malicious instructions. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
