The Anti-Rootkit Rootkit - victorbush
WebApr 21, 2015 · However, there is a native API function called ZwSystemDebugControl that allows us to read and write kernel memory from user-mode applications [1]. The procedure for using ZwSystemDebugControl is outlined nicely in the Malware Analyst’s Cookbook [1] with code cross-reference to the OpenRCE blog [2].
Putting ZwSystemDebugControl to good use - OpenRCE
WebHere is a small example of a really simple and naive rootkit detection code that is fully user-mode. It works with 100% of commercial spyware/keygens that I've tried, but of course not with the experimental "scene" rootkits that can use Kernel Object hooking, memory obfuscation to change the contents of this table, or even injecting code within ...
Read Kernel Memory from user mode WITHOUT driver
WebApr 25, 2016 · Check if HANDLEENTRY.bType is 5 (which means it's a HHOOK). If so, print informations. The problem is, although step 1-3 only mess around with user mode memory, step 4 requires the program to read kernel memory. After some research I found that ZwSystemDebugControl can be used to access Kernel Memory from user mode.

Named Kernel Exports Added for Windows 10 Version 1903 ...
WebZwSystemDebugControl As with many Zw functions, ZwSystemDebugControl has earlier history as a user-mode export from NTDLL.DLL—indeed, in this case all the way back to version 3.10. A declaration thus appears in the ZWAPI.H header that Microsoft published only in early editions of the WDK for Windows 10.
