Microsoft Copilot’s Audit Logs Had a Silent Security Hole

A critical flaw in Microsoft Copilot allowed users to bypass activity logs, letting insiders summarize confidential files without leaving a trace. Discovered by Zack Korman, CTO at Pistachio, the vulnerability exploited the way Copilot recorded—or didn’t record—file access. Malicious actors could have quietly siphoned sensitive data, undermining compliance standards Copilot promises.

Microsoft patched the issue on Aug. 17, 2025, but did not assign a CVE, frustrating researchers. This incident highlights a larger truth: enterprise AI isn’t secure just because it’s integrated—it’s only as safe as its guardrails.

Key Takeaways:

  • Ghost activity: Copilot could be told not to log document summaries, leaving audit logs blank.

  • Insider risk: Malicious employees could access sensitive data undetected.

  • Prompt injection concern: Researchers previously flagged similar vulnerabilities, showing a pattern of weaknesses.

  • Silent fix, opaque process: Microsoft patched it quietly without formal CVE, leaving some security researchers dissatisfied.

Trust in enterprise AI isn’t about features—it’s about whether the system can resist deliberate manipulation.
