A good debugger could read/write into MSRs, a better debugger could also *intercept* any application or driver trying to read or write into MSRs, and let you modify values, or block the MSR access altogether. 😉

I've always been interested in Model Specific Registers (MSRs). They're rarely used by application code; they're in the domain of operating systems, hypervisors, firmware, and low-level processor features. My debugger can now selectively access these; but don't crash the system.

I'm pleased to announce @HyperDbg v0.19.
This release introduces a new module, HyperTrace, which brings hypervisor-level integration w/ tracing technologies such as Last Branch Record (LBR) & Processor Trace (PT).
LBR is now available, with more coming.

Major milestone forward for HyperDbg supporting #Linux.
We've made a major progress on porting HyperDbg to Linux (still a long road ahead). Now the HyperDbg SDK can be compiled with GCC for both user/kernel modes on Linux.
More updates coming soon...👀

Our paper "TRM: The Reversing Machine" has been accepted to @asiaccs2026!
TRM is developed on top of @HyperDbg and exposes stealthy sub-OS malware using transparent hypervisor introspection, detecting threats missed by 24 AV engines.
