'CoSnitch' Attack Tricked Copilot into Mapping Out Architecture

August 18, 2026 · Dark Reading · Severity: MEDIUM

Researchers discovered a meta-hacking technique called CoSnitch that can manipulate Microsoft Copilot into revealing its own security weaknesses. The attack exploits AI assistants to map out internal architecture and identify vulnerabilities by tricking the AI service into disclosing sensitive information about its security posture. Organizations should test AI tools for unintended information disclosure and prompt injection risks as these attack vectors continue to evolve.

Key Takeaways

  • Meta-hacking technique manipulates Microsoft Copilot into revealing its own security weaknesses.
  • CoSnitch attack exploits AI assistants to map out internal architecture and find vulnerabilities.
  • Organizations should test AI tools for unintended information disclosure and prompt injection risks.
