A Novel Call Stack Spoofing Technique for Reflectively Loaded Modules maxdcb.github.io/DreamWalkers/ TLDR: Traditional reflective loaders often fail to convincingly spoof call stacks, leaving behind traces that advanced EDRs and analysts can detect. DreamWalkers changes the game.
Here's the little book about OS development! This wonderful little book guides you on how to get an OS working, start to finish. It's written in C, and you can learn an absolute ton on how PCs work with this. Enjoy!
Over the past few months, I've been working on shadow-rs, a Windows Kernel Rootkit in Rust with various features. Huge thanks to @zodiacon for his Windows Kernel Programming book, @Idov31 & @eversinc33 for inspiration & discussions! github.com/joaoviictorti/…

I published part 5 of my "Writing a .NET profiler in C#" series. All the foundations built in the previous articles have been moved to a library named Silhouette. In this new article, we finally have everything we need to write an actual profiler.
TIL Windows keeps a record of your notifications under %localappdata%\Microsoft\Windows\Notifications. This is not locked under any privileged ACE. You can use this to exfiltrate possibly sensitive data sent over push notifications, if not build a timeline for recon.

You wait ages for a bus to arrive.... up until last week, most 'AI will help find and exploit bugs' papers were shit. I've chosen that word for a reason, they truly were. Jumping on that hype train hoping to prove they are the driver. However, stuff just got somewhat real
This is a pretty nice graphic explaining how Kerberos Auth takes place. Useful to have as a reference when you have to explain and visualize attacks such as Pass The Ticket, Kerberoasting and AS-REP Roasting. Credit: @0xNarek 🙏🙏
the xz sshd backdoor rabbithole goes quite a bit deeper. I was just able to trigger some harder to reach functionality of the backdoor. there's still more to explore.. 1/n

I've been reverse engineering the xz backdoor this weekend and have documented the payload format and written a proof-of-concept exploit for the RCE. The payloads are signed with an ED448 key, so I patched my own key into the backdoor for testing. :-) github.com/amlweems/xzbot
New blogpost and small tool release: Wrote a naive anti-rootkit driver that detects mapped drivers, and talk about some bypasses for those detections in part I of my new (anti-)-anti-rootkit series. More research on rootkit evasion coming soon : ) eversinc33.com/posts/anti-ant…
A challenge: can you bypass Defender by suspending all its threads?🤯 Works on the fully updated Windows! And where is the challenge? Is the above description enough for you? I am asking because @msftsecresponse have just closed my submission because no pictures were attached :D
