PowerShell Standard Library: Build single module that works across Windows PowerShell and PowerShell Core
This is the first of a series of blog posts that will help you take advantage of a new NuGet package PowerShellStandard Library 5.1.0. This package allows developers to create modules that are portable between Windows PowerShell 5.1 and PowerShell Core 6.0. This means that you can create PowerShell modules that run on Windows, Linux, and macOS with a single binary! The version of PowerShell Standard Library indicates the lowest version of PowerShell that it is compatible with. The community promise is that it is always forward compatible. So a module built against PowerShell Standard Library v3 is compatible w...
PowerShell Injection Hunter: Security Auditing for PowerShell Scripts
At the DEFCON security conference last year, we presented the session: "<a href="https://www.youtube.com/watch?v=ahxMOAAani8">Get $pwnd: Attacking Battle Hardened Windows Server</a>". In this talk, we went through some of the incredibly powerful ways that administrators can secure their high-value systems (for example, Just Enough Administration) and also dove into some of the mistakes that administrators sometimes make when exposing their PowerShell code to an attacker. The most common form of mistake is script injection, where a script author takes a parameter value (supplied by an attacker) and runs it in a...
Increased Windows Modules coverage with PowerShell Core 6.1
During the May 2018 Community Call and a tweet a few weeks later, we mentioned that PowerShell team was spending significant time in the Windows codebase. We even demoed using the Active Directory PowerShell Module from PowerShell Core 6 during the PowerShell Community Call. We started investigating some of the top requested modules that ship with Windows to see how to get them working in PowerShell Core 6. Our eventual goal is to have near 100% parity with Windows PowerShell for the in-box modules, but we expect this effort to span across multiple releases of Windows as there are many modules and PowerShell tea...

PowerShell Core now available as a Snap package
The goal of PowerShell Core is to be the ubiquitous language for managing your assets in the hybrid cloud. That's why we've worked to make it available on many operating systems, architectures, and flavors of Linux, macOS, and Windows as possible. Today, we're happy to announce an addition to our support matrix: PowerShell Core is now available as a Snap package. What's a Snap package? Snap packages are containerized applications that can be installed on many Linux distributions. For more info, check out Canonical's blog on our Snap announcement. What does this do for me? Snap packages have a number of benefit...
