Excellent write-up on stealth hooking with hypervisors on the Intel processors. It discusses two different approaches in detail with actual implementations you can play with.

Just wrapped up teaching my hypervisor development class. Always refreshing to work with sharp folks from diverse backgrounds—and rewarding to help them get started. The next class will be in person at @hexacon_fr. Check out the conference page if you're interested.

It is amazing to see someone taking a class and then making stellar output by extending what they learned in the class. Obviously, @_jaelkoh dedication was the key, but also, @saidelike must have done a fabulous job helping his students learn and get started. Very cool.
The video for my talk at @offensive_con with @saidelike is out! It was an absolute pleasure working with Cedric on this dream of mine! .

My talk about the recent SMM architecture and security at @TheSAScon : The conference was well organized and had plenty of networking opportunities. Though, the best thing was the venue :) It is at a beautiful resort again this year, so you will love it.

This is like "VT-x 101". The essence of HW-assisted VT, everything needed to virtualize Windows on-the-fly, and a bit of security in 2 days. It misses a ton of fun discussions and exercises that are in my 4 days class, but I am giving back to the community that helped me learn.
We wanted to point out specifically the update to the System Security Learning Path that the excellent low level engineer & researcher Satoshi Tanda @standa_t has agreed to create our long-desired 'Architecture 3001: Intel Virtual Machine Extensions (VMX)' class!.

The Documentation Change file got updated. Thank you @IntelSupport for fixing it quickly!.
Intel SDM rev 87 was out. Updates? Good luck with diffing 5000+ pages of PDF files. @intel forgot to update the Documentation Changes file.

Excellent post on Samsung's hypervisor! . I did not know they too were transitioning to Rust. Good move.
I've published a write-up on reversing and analyzing Samsung's H-Arx hypervisor architecture for Exynos devices, which has had a lot of changes in recent years and pretty interesting design. Hope you all enjoy :).

Added AMD support to hvext, the windbg extension for reversing Hyper-V!. You can easily check what SVM features are enabled, which MSRs and IO ports are accessible, and how nested page table looks like, for NT, SK and regular VMs.
