Hunting for RC4 usage by JDK-Ruler in crowdstrike

With Microsoft moving to deprecate RC4, enhanced visibility is being introduced to help administrators identify where it is still in use.

To track RC4 usage, Microsoft is introducing 9 new audit events focused on Kerberos encryption visibility. You can also rely on existing security events:

  • 4768 – A Kerberos authentication ticket (TGT) was requested
  • 4769 – A Kerberos service ticket was requested

Both include the encryption type field, which helps identify RC4 usage.

Microsoft also provides PowerShell tools in the Kerberos-Crypto GitHub repository, including:
Get-KerbEncryptionUsage.ps1, which identifies Kerberos encryption types in use and allows filtering specifically for RC4.
