Why we do it?

Password spraying is a crucial technique in penetration testing to discover weak or reused passwords without triggering account lockouts.

For Windows, DomainPasswordSpray stands out for a few key reasons:

🔹 It can include AD valid users when performing password spraying if you’re authenticated. This feature automates the inclusion of valid users from the AD, saving time and effort.

Import-Module .\DomainPasswordSpray.ps1

Once imported, we run it this way:

Invoke-DomainPasswordSpray -Password…
