ποΈ In this episode, Craig Birch dives into a critical but often overlooked AD misconfiguration: accounts that allow password storage with reversible encryption.
This setting can bypass your domain password policies and expose credentials to plaintext extraction by tools like Mimikatz or DCSync.
π What Youβll Learn:
β’ Why reversible password encryption is still found in AD environments
β’ How it allows attackers to dump plaintext passwords
β’ How to find accounts with this setting using PowerShell
β’ Steps to remediate and eliminate this risky configuration
β’ Why this setting defeats complexity, length, and hashing protections
π οΈ PowerShell Spotlight:# Find users with reversible encryption enabled
Get-ADUser -Filter {AllowReversiblePasswordEncryption -eq $true} `
-Properties AllowReversiblePasswordEncryption |
Select-Object Name, SamAccountName
# Optional: Remediate the setting
Set-ADUser username -AllowReversiblePasswordEncryption $false
β Use this to eliminate one of the most easily exploitable password risks in AD.
β Quick Takeaways:
Reversible encryption = plaintext storage risk
Bypasses password complexity and policy protections
Vulnerable to Mimikatz, DCSync, and backup extraction
Use PowerShell to quickly find and fix weak accounts
