CERT-EU shows a backdoored coding-agent extension can steal credentials without the model

CERT-EU's AI team planted a trigger in two otherwise working third-party extensions for coding-agent harnesses and collected host details, environment variables and credential files in the background, with no tool call for agent-level controls to catch. For IBM i developers using Bob or any coding agent, treat extensions as privileged code: pin and inventory them, keep IBM i passwords and SSH keys out of environment variables and the workspace, and connect from the workstation with a low-authority developer profile, never one with *ALLOBJ.
