'Ghostcommit' hides prompt injection in images to fool AI agents, steal secrets

BleepingComputer

Researchers have demonstrated a new technique called 'Ghostcommit' that can hide prompt injection attacks within PNG image files. This method allows attackers to bypass AI code reviewers like CodeRabbit and Bugbot, which do not examine image files. Once the image is processed by a coding agent, it can lead to unauthorized access to sensitive information, such as secrets stored in a repository's .env file. This technique poses a serious risk to software developers and organizations that rely on automated code review tools, as it can result in the exposure of confidential data. The ability to extract secrets and convert them into a readable format makes it a significant concern for data security.
