Windows Feature Hunter

optional arguments:
  -h, --help            show this help message and exit
  -t T [T ...], -targets T [T ...]
                        list of target windows executables
  -m {dll,com}, -mode {dll,com}
                        vulnerabilities to potentially identify
  -v, -verbose          verbose output from Frida instrumentation
  -timeout TIMEOUT      timeout value for Frida instrumentation

EXAMPLE USAGE
    NOTE: It is recommended to copy target binaries to the same directory as wfh for identifying DLL Sideloading

    DLL Sideloading Identification (Single):        python wfh.py -t .\mspaint.exe -m dll
    DLL Sideloading Identification (Verbose):       python wfh.py -t .\mspaint.exe -m dll -v
    DLL Sideloading Identification (Timeout 30s):   python wfh.py -t .\mspaint.exe -m dll -timeout 30
    DLL Sideloading Identification (Wildcard):      python wfh.py -t * -m dll
    DLL Sideloading Identification (List):          python wfh.py -t .\mspaint.exe .\charmap.exe -m dll

    COM Hijacking Identification (Single):          python wfh.py -t "C:\Program Files\Internet Explorer\iexplore.exe" -m com
    COM Hijacking Identification (Verbose):         python wfh.py -t "C:\Program Files\Internet Explorer\iexplore.exe" -m com -v
    COM Hijacking Identification (Timeout 60s):     python wfh.py -t "C:\Program Files\Internet Explorer\iexplore.exe" -m com -timeout 60
    COM Hijacking Identification (Wildcard):        python wfh.py -t * -m com -v
    COM Hijacking Identification (List):            python wfh.py -t "C:\Program Files\Internet Explorer\iexplore.exe" "C:\Windows\System32\notepad.exe" -m com -v
