Finally, the HyperDbg course is now live at @OpenSecTraining! In this tutorial, I explore the potential of using HyperDbg for enhanced reverse engineering, alongside a lot of hypervisor-based reverse engineering tricks!
📣New #OST2 class!!!📣"Debuggers 3301: HyperDbg"📣 ost2.fyi/Dbg3301 This ~16 hour class (based on average beta tester completion time) by Sina Karvandi @intel80x86 covers his hypervisor-based debugger HyperDbg
We have received reports @HyperDbg's latest release shows unexpected behavior. As it turns out, this is due to a compiler optimization bug in Visual Studio 17.14.8 and 17.14.9. We have pushed a temporary workaround fixing the build. Thanks for reporting! (1/2)

Apparently, Windows 11 24H2 uses the new 'TPAUSE' instruction. If your hypervisor fails on Raptor/Meteor/Lunar Lake (or maybe older CPUs?), you may need to adjust secondary processor-based VM controls again to enable this capability on VMCS for your hypervisor.
