New blog post! 📰 RD Gateway Without KDC Proxy Causes NTLM Downgrade 💥 mstsc assumes the RD Gateway is a KDC proxy — if it isn't, Kerberos fails with an NTLM fallback! ⚠️ Learn about this undocumented mstsc behavior and how to work around it 👇

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 if you receive a DM from a bridge bot, I requested that. It's to interact with you from Bluesky
We're happy to announce Devolutions is sponsoring WebAssembly optimizations for our zlib in Rust project, zlib-rs!
Devolutions, the Diamond sponsor of this year's RustConf, is a leading security partner with over 800,000 users across 140 countries.
Special thanks to Devolutions' CTO @awakecoding who helped make this sponsorship happen.
Our maintainers, @folkertdev and @bjorn3 have made a lot of progress already. Stay tuned for an update!
@obilodeau the blog post is dated from today, was there another one last week?
@obilodeau hey check your Twitter, malicious RDP servers have been used in targeted spear-phishing attacks: https://x.com/MsftSecIntel/status/1851339475227377848
@KirillOsenkov @rainer @chethusk we nuked the Microsoft.Windows.SDK.NET.Ref reference as a workaround: https://github.com/dotnet/sdk/issues/44026#issuecomment-2432599653
@KirillOsenkov @rainer @chethusk I think he already got tagged on https://github.com/dotnet/sdk/issues/44026
@rainer @KirillOsenkov @chethusk I enabled diagnostic build logging to see if CsWinRTAotOptimizerEnabled is set to false, and it is... so something's not right
@rainer @KirillOsenkov @chethusk this appears to be the exact commit responsible for the regression: https://github.com/dotnet/sdk/commit/ec0ad19377bc77ea1d394220bd6a76c01191341d
@rainer @KirillOsenkov @chethusk I can confirm that the issue appears with SDK 8.0.403. We're 3 people trying to figure out what magical msbuild modification we need to make, but either <CsWinRTAotOptimizerEnabled>false</CsWinRTAotOptimizerEnabled> doesn't work, or we're trying to set it in the wrong places. The WinRT source generator keeps getting called
@zombie042 from experience, a simple Visual Studio update that enables some useless feature that totally kills our build performance is much more likely
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
@gigantos yes, if you switch to Entra ID, it is not Active Directory
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
@cxiao I've got a script that Jordan made using PSDetour to load PowerShell into lsass.exe and dump the TLS premaster secrets for Wireshark decryption: https://github.com/awakecoding/wireshark-rdp
