Cordyceps Campaign Poisons CI/CD Workflows in Open Source

Cordyceps Campaign Poisons CI/CD Workflows in Open Source

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 7.2 Dark Reading

A campaign dubbed 'Cordyceps' is exploiting weaknesses in CI/CD workflows to inject malicious pull requests into high-profile open-source projects, including Google's AI Agent Development Kit and Microsoft's Azure Sentinel. The attack surface spans multiple trusted ecosystems, meaning poisoned code could propagate into AI tooling, cloud infrastructure, and widely-used developer utilities before detection. The breadth of targets — including Python's Black formatter — signals a supply chain strategy designed to maximise downstream blast radius.

Loopsy AI Agent Relay Enables Cross-Machine RCE

ATLAS OWASP MEDIUM Moderate risk · Monitor closely ▲ 6.5 HN AI Security

Loopsy is an open-source tool enabling cross-machine communication between AI coding agents (Claude Code, Cursor, Codex) and mobile devices via a self-hosted Cloudflare Workers relay. While designed for legitimate developer productivity, the architecture introduces significant attack surface: a relay brokering shell access and AI agent commands across machines is a high-value target for interception, hijacking, or supply chain compromise. Security teams should assess exposure before deploying such tools in sensitive development environments.
