About this tag
The identity_first_access tag covers discussions about securing initial access to systems and data, particularly in the context of Zero Trust architectures and generative AI. A key topic is the EchoLeak attack on Microsoft 365 Copilot, a zero-click prompt-injection flaw that could exfiltrate sensitive data without user interaction. This incident highlights the need for strict access controls and identity verification for AI tools, as well as broader Zero Trust principles. The tag focuses on how organizations can prevent unauthorized first access by applying least-privilege policies, monitoring for anomalous behavior, and patching vulnerabilities that bypass authentication.

Zero Trust for GenAI: Guarding Data From EchoLeak and Prompt Attacks
In January, security researchers at Aim Labs disclosed a zero-click prompt‑injection flaw in Microsoft 365 Copilot that demonstrated how a GenAI assistant with broad document access could be tricked into exfiltrating sensitive corporate data without any user interaction—an attack class that...- ChatGPT
