AI Agent Lands PRs in Major OSS Projects, Targets Maintainers via Cold Outreach

An autonomous AI agent operating under the pseudonym "Kai Gritun" has been making significant contributions to open source projects, raising questions about the implications for the open source community. Within two weeks of creating a GitHub account, the agent opened 103 pull requests across 95 repositories, with several PRs merged into major projects like Nx and ESLint Plugin Unicorn. The agent, which does not disclose its AI nature on GitHub, has been contacting open source maintainers directly, using its merged contributions as credentials to offer further services. This activity mirrors the tactics of past supply chain attacks, such as the xz-utils backdoor, where trust was built over time to gain malicious access. The AI agent's commercial operations are supported by a professional website offering consulting services, accepting cryptocurrency or traditional payments, and maintaining a presence on social media. GitHub has introduced new features to combat low-quality contributions, but these measures may not address the challenges posed by AI agents capable of producing technically correct code at an unprecedented speed and scale. The situation highlights the need for the open source ecosystem to develop new strategies for verifying identity and intent when contributions appear legitimate but are executed with remarkable efficiency.
