Refi Hub co-founder warns of Claude malicious link attack

This incident underscores a growing attack surface: AI assistants are now a vector for credential theft, not just a productivity tool. For teams integrating agents into daily operations, the risk shifts from prompt injection to persistent, file-based compromise. The significance lies in how skill files—trusted components of an AI workflow—can be weaponized, making supply-chain integrity a core security concern. The open question is whether platform providers will respond with stronger sandboxing and file-level permissions, or if users will bear the burden of vetting every asset their AI touches.
