As a cybersecurity researcher and open-source developer, I am all about Active Directory, Entra ID, Passkeys, and PowerShell. I typically publish my findings to my blog. My flagship projects are the DSInternals PowerShell module and Active Directory Firewall.

PowerShell Modules

  • 📑DSInternals - Active Directory password auditing, ntds.dit database file manipulation, and much more.
  • 🔑DSInternals.Passkeys - Administrative registration of passkeys in Microsoft Entra ID and Okta.
  • 🛡️DSInternals.RpcFilters - Management of RPC filters in the Windows Filtering Platform (WFP).

NuGet Packages

Functionality exposed in my PowerShell modules is also available through these NuGet packages, aimed at .NET developers:
