Request for new features - CPUID - RDTSC #6

Closed UnlimitedChild closed 3 years ago

UnlimitedChild commented 3 years ago

Hi,

some features, CPUID and RDTSC Hooking, are missing in this plugin.

Best regards

Air14 commented 3 years ago

Rdtsc is in my opinion too sensitive to hook so this feature probably won't be implemented. Also what information would you want to hide with cpuid hooking?

UnlimitedChild commented 3 years ago

Modern security tools use these methods to detect program debugging. CPUID is used to bind the program execution environment and to perform antidump protection. hypervisor_example_rdtsc-master.zip

'CPUID' can detect vm, It will detect the Hypervisor, for this type, it will be treated as a virtual machine environment.

Does this plugin have nested virtualization support ?!
