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...👀

https://github.com/HyperDbg/HyperDbg/tree/dev/hyperdbg/linux

Just another day at the HyperDbg project...

We are 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.

https://github.com/HyperDbg/HyperDbg/releases/tag/v0.19

This release wouldn't have been possible without the help and outstanding work of @maxraulea, @masoudrahimi01, @jtaw5649, @harimishal1, @Idov31.

Along with extensive refactoring & numerous bug fixes, two new LBR commands have been added:

The '!lbr' command:
https://docs.hyperdbg.org/commands/extension-commands/lbr

The '!lbrdump' command:
https://docs.hyperdbg.org/commands/extension-commands/lbrdump

Also, the script engine now includes 5 new functions to support LBR:
https://docs.hyperdbg.org/commands/scripting-language/functions/tracing/lbr

Other than that, the '.pe' command has been extensively changed and enhanced:
https://docs.hyperdbg.org/commands/meta-commands/.pe

HyperDbg v0.20 is out! 🎉

This release includes numerous bug fixes, continued progress on the Linux port, further advancements in Intel PT support, and a migration to Visual Studio 2026.

Check it out:
https://github.com/HyperDbg/HyperDbg/releases/tag/v0.20-beta

HyperDbg v0.21 is released! 🪐💫

This release includes numerous bug fixes, improved stability, and significant progress toward integrating Intel PT (Processor Trace) into HyperDbg.

Check it out:
https://github.com/HyperDbg/HyperDbg/releases/tag/v0.21

Need to debug interrupts, faults, or exceptions? HyperDbg has plenty of commands to help!

Use !exception to intercept exceptions (the first 32 entries of the IDT) and !interrupt to intercept interrupts (IDT entries 32–255).

You can also step through ISR instructions, inspect the IDT with !idt, and explore the Local APIC and I/O APIC state in both xAPIC and x2APIC modes using !apic and !ioapic.

If you want to create (inject) artificial interrupts, HyperDbg provides a variety of functions for that as well.

Check it out:

!exception:

This release adds support for floating-point variables in the script engine & introduces the new 'ucpuid' command, which displays selected CPUID leaves, interprets and maps them to the processor-defined flags.

Check it out:
https://github.com/HyperDbg/HyperDbg/releases/tag/v0.23

This version also brings Linux support for compiling user-mode code. Alongside these new features, this release includes numerous bug fixes and code quality improvements.

Happy debugging! 🌺🌼🌻

It's been a while since we passed 4K GitHub stars ⭐️

And more good news: HyperDbg's kernel-mode drivers now build on #Linux! 🐧

After successfully getting the user-mode components compiled, thanks to @MaxRaulea, we're now moving on to debugging, implementing, and testing cross-platform functionality.

Step by step, we’re getting closer to running HyperDbg on Linux!
