RD Gateway Without KDC Proxy Causes NTLM Downgrade

Learn why mstsc requires the RD Gateway to act as a KDC proxy for Kerberos authentication, how this undocumented behavior causes silent NTLM downgrades, and how to fix it by enabling the KDC proxy service.

New release of zlib-rs!
We are now (to our knowledge) the fastest zlib implementation, beating C implementations like zlib-ng.

What is zlib? zlib likely (de)compressed the page you're reading right now!

With thanks to @folkertdev @bjorn3 @josh @awakecoding and many others!

Had some fun working with a challenge posed by @awakecoding A POC that can run multiple #PowerShell named pipe instances with custom pipe names. Usually you have to start a new process but this can be done in proc. Non-public APIs so not production code https://gist.github.com/jborean93/43c8338accc3f0eee95f8c43fec61e6f

As far as we know, our zlib-rs is the fastest WASM zlib implementation today.
Knowing SIMD is incredibly effective for the zlib algorithms, we were excited to use the WASM SIMD instructions. Read about the work and results:

Special thanks to our sponsor Devolutions for supporting the WASM SIMD milestone.

And to our maintainers, @folkertdev and @bjorn3 for the amazing work.

@obilodeau hey check your Twitter, malicious RDP servers have been used in targeted spear-phishing attacks: https://x.com/MsftSecIntel/status/1851339475227377848
Microsoft Threat Intelligence (@MsftSecIntel) on X

The spear-phishing emails in this campaign were sent to thousands of targets in over 100 organizations and contained a signed Remote Desktop Protocol (RDP) configuration file that connected to an actor-controlled server.

Anybody else seeing WinRT.SourceGenerator suddenly taking a whopping 30 seconds in their .NET 8 application build time? What's even more puzzling is that it's not generating anything, we don't need it, and we don't know when that generator first appeared

Do you plan to fully decommission Active Directory within the next 5 years? By this, I mean getting rid of domain controllers *entirely*, without hybrid-joined systems
