用于 Windows 系统调用调查的工具和 PoC。
此目录用于 Heaven's Gate 技术。 参见 README.md
该工具用于从 ntdll.dll 或 win32u.dll 转储 Windows 系统调用：```
C:\Tools>SyscallDumper.exe -h
SyscallDumper - Tool to dump syscall.
Usage: SyscallDumper.exe [Options] [INPUT_DLL_1] [INPUT_DLL_2]
-h, --help : Displays this help message.
-d, --dump : Flag to dump syscall from ntdll.dll or win32u.dll.
-D, --diff : Flag to take diff between 2 dlls.
-f, --format : Specifies output format. "c" for C/C++, "cs" for CSharp, "py" for Python.
-n, --number : Specifies syscall number to lookup in decimal or hex format.
-o, --output : Specifies output file (e.g. "-o result.txt").
-s, --search : Specifies search filter (e.g. "-s createfile").
INPUT_DLL_1 : Specifies path of ntdll.dll or win32u.dll. Older one in diffing.
INPUT_DLL_2 : Specifies path of ntdll.dll or win32u.dll. Newer one in diffing.
若要从 ntdll.dll 或 win32u.dll 转储系统调用号，请使用 `-d`（`--dump`）选项。
如果未指定源 DLL，该工具将从 `C:\Windows\System32\ntdll.dll` 和 `C:\Windows\System32\win32u.dll` 转储系统调用号：```

如果你想从转储结果中筛选系统调用名称，可以使用 -s (--search) 选项。并且你可以使用 -o (--output) 选项将结果保存到文件，如下所示：```
C:\Tools>SyscallDumper.exe -d C:\SyscallSamples\1809x64\ntdll.dll -s token -o result.txt
[>] Loading C:\SyscallSamples\1809x64\ntdll.dll. [+] C:\SyscallSamples\1809x64\ntdll.dll is loaded successfully. [] Architecture : AMD64 [] Image Name : ntdll.dll [+] Got 462 syscall(s). [>] Trying to save results. [*] Output File Path : c:\Tools\result.txt [+] Results are saved successfully.
c:\Tools>type result.txt [Syscall Table from C:\SyscallSamples\1809x64\ntdll.dll]
[] Found 18 syscall(s). [] Filter String : "token"
使用 `-n`（`--number`）选项，您可以按系统调用号码查找系统调用名称，如下所示。
如果您想以十六进制格式指定系统调用号码，应以 "0x" 开头。```
