Microsoft Copilot reveals secret input that allowed it to be hacked
Source: Ars Technica · Dan Goodin
Intel Summary
A security vulnerability in Microsoft Copilot allowed attackers to steal user passwords when a target clicked a malicious link. The exploit leveraged an undisclosed input parameter within the AI assistant to compromise user security guardrails and exfiltrate credentials. Reported by security journalist Dan Goodin, the flaw underscores critical risks surrounding hidden application interfaces and prompt handling in commercial AI tools.
Why It Matters
Enterprise deployment of AI assistants introduces new attack vectors where subtle parameter manipulation can bypass traditional application security boundaries. With Copilot embedded across enterprise workflows and operating systems, vulnerabilities that permit credential theft via simple link interaction present immediate identity and access management risks for IT administrators and security teams.
