Forensic Summary
The article examines 'toxic combinations' — a compounding risk pattern where AI agents and OAuth integrations bridge multiple SaaS applications, creating attack surfaces that no single application owner reviews. A real-world case involving Moltbook exposed 1.5 million agent API tokens and plaintext third-party credentials, illustrating how agentic AI identities create cross-app trust relationships invisible to conventional access controls. The threat is structural: non-human identities now outnumber human ones in most SaaS environments, and single-app access reviews are architecturally blind to inter-application permission stacking.
