Pass the Hash Guidance

This project hosts scripts for aiding administrators in implementing Pass the Hash mitigations as outlined in the Reducing the Effectiveness of Pass the Hash paper.

The PtHTools module contains the main commands for helping with implementing PtH mitigations:

• Find-PotentialPtHEvents
• Invoke-DenyNetworkAccess
• Edit-AllLocalAccountPasswords
• Get-LocalAccountSummaryOnDomain
• Invoke-SmartcardHashRefresh
• Find-OldSmartcardHash

See the PtHTools readme file for more information on how to use them.
