ATT&CK analytic guidance
DET0240 Detection Strategy for Steal or Forge Authentication Certificates
AN0671 Analytic 0671
Monitor for abnormal certificate enrollment and usage activity in Active Directory Certificate Services (AD CS), registry access to certificate storage locations, and unusual process executions that attempt to export or access private keys.
AN0672 Analytic 0672
Monitor for file access to certificate directories, commands invoking OpenSSL or PKCS#12 utilities to export or modify certificates, and processes accessing sensitive key storage paths.
AN0673 Analytic 0673
Monitor for security commands and API calls interacting with the Keychain, as well as file access attempts to stored certificates and private keys in ~/Library/Keychains or /Library/Keychains.
AN0674 Analytic 0674
Monitor for abnormal certificate enrollment events in identity platforms, unexpected use of token-signing certificates, and unusual CA configuration modifications.

Exact source tags are not semantic relevance verdicts. Review actual rule conditions and observation points; imported rules are not backend-compiled or live-validated.
Pinned research references. No browser attack runner or production-validated detector is asserted. Imported procedures remain unvalidated; any bounded lab evidence has its own scope. ATT&CK / Atomic provenance · Detection provenance.
