NtQueryWnfStateData vs. NtDll.dll: Understanding the Difference and the "Better" Approach

NTSTATUS NtQueryWnfStateData( _In_ HANDLE StateHandle, _In_opt_ PWNF_CHANGE_STAMP ChangeStamp, _Out_ PVOID Buffer, _In_ ULONG BufferSize, _Out_opt_ PULONG DataSize, _Out_opt_ PWNF_CHANGE_STAMP ChangeStampResult );

WNF state data contains ephemeral system data that is difficult to retrieve through standard means. NtQueryWnfStateData allows forensic tools to snapshot system states that aren't persisted to disk, providing a clearer picture of what the machine was doing at a specific moment.

Exploit Research

: Security researchers have historically looked at WNF functions like NtUpdateWnfStateData and NtQueryWnfStateData to understand kernel memory management and potential vulnerabilities (e.g., CVE-2021-31956). Troubleshooting ntdll.dll Crashes
