OpenPGP Private Key

Service Name: OpenPGP

Service Description: OpenPGP is a standard for encrypting and signing data that provides cryptographic privacy and authentication. It's commonly used for securing email communications, file encryption, and digital signatures.

Service Address: https://www.openpgp.org/

Validation Type: Unavailable

IP Allow list: Does not exist

Secret Access Scope: Grants ability to decrypt messages encrypted with the corresponding public key and to create digital signatures that can be verified with the public key.

Secret Revokement URL: Does not exist (though revocation certificates can be generated and published to keyservers)

Secret Example:

Suspicious Activity Investigation Instructions:

  • Check for unauthorized access to systems where the private key is stored

  • Review logs for any unexpected file decryption or signing operations -----BEGIN PGP PRIVATE KEY BLOCK----- Version: GnuPG v2.0.22 (GNU/Linux) lQcYBGJDkYUBEADMhRdmPsA0qdlowZRgGFrLAgNLfvjf9BeMJiUhj3FTYIIj9J4B HkwSJ7M8uWT/YgCxYBEOKNO8HRYnX8AvlwRvAoUNYt7k5WZfuL9JNZlrIFfMgDJD QOLGSELsg0Euuv6/EYqG6+hDxDrJEh1CkAXU5TlqsqGzMnUwgIjpKQa7PZkggXSX WQQUqGZJEGgEgAUdlHOWBzh+ =ABCD -----END PGP PRIVATE KEY BLOCK-----

  • Monitor for unexpected communications or data exfiltration that might be using

the compromised key

  • Check if the corresponding public key has been used in unexpected places or

contexts

  • Verify if any encrypted communications have been compromised

Mitigation Instructions:

  • Generate a new key pair immediately
  • Revoke the compromised key by publishing a revocation certificate to key servers
  • Notify all parties who use your public key that it has been compromised
  • Update the key in all systems and applications where it was used
  • Rotate any credentials or secrets that were encrypted with the compromised key
  • Review and strengthen access controls to private key storage
  • Consider implementing hardware security modules (HSMs) for storing private keys
  • Implement stronger passphrase protection for any new keys
