https://cocomelonc.github.io/malware/2025/12/25/malware-tricks-55.html next one from my blog. Another classic technique in malware development to stay away from the more obvious Win32 APIs.

As far as I know this function used by Process Hacker, for performance in process enumeration.

The MHook library also got a significant performance boost when switching from CreateToolhelp32Snapshot to NtQuerySystemInformation

Another caveat, by intercepting calls to the NtQuerySystemInformation function, we also can hide a some specified process, from common process monitoring tools such as Task Manager and Process Hacker. This is also an interesting trick in malware development, but I will write about this in a separate post.

Thanks to ANY.RUN for the API ♥️
