I installed pcapy on a Windows machine, but importing in Python failed due to a missing DLL.

Process Monitor showed me what was missing: wpcap.dll, a WinPcap DLL:

The DLL was missing because I had installed Npcap (an alternative for WinPcap, that provides loopback packet capture).

This problem can be fixed by setting a toggle to install a WinPcap compatible API (e.g. wpcap.dll) during installation:

Windows executables (PE files) can be signed on Kali using osslsigncode.

osslsigncode needs to be installed:

apt install osslsigncode

Then you need a certificate. For this demo, I’m using a self-signed cert.

The command to sign file demo-x64.exe with the demo certificate using SHA1 and timestamping, is:

osslsigncode sign -certs cert-20180729-110705.crt -key key-20180729-110705.pem -t http://timestamp.globalsign.com/scripts/timestamp.dll -in demo-x64.exe -out demo-x64-signed.exe

The signed file is demo-x64-signed.exe

To dual sign this executable (add SHA256 signature), use this command:

osslsigncode sign -certs cert-20180729-110705.crt -key key-20180729-110705.pem -t http://timestamp.globalsign.com/?signature=sha2 -h sha256 -nest -in demo-x64-signed.exe -out demo-x64-dual-signed.exe

The signed file is demo-x64-dual-signed.exe

Of course, Windows reports the signatures as invalid, because we used a self-signed certificate. For a valid signature, you can add your certificate to the trusted root certificates store, buy a code-signing certificate, …

For single SHA256 signing, use the second osslsigncode command without option -nest.

To compile a Windows executable with version information and an icon on Kali, we use MinGW again.

The version information and icon (demo.ico) we want to use are defined in a resource file (demo.rc):

#include "winver.h" #define IDI_ICON1 101 ///////////////////////////////////////////////////////////////////////////// // // Version // #define VER_FILEVERSION 0,0,0,1 #define VER_FILEVERSION_STR "0.0.0.1\0" #define VER_PRODUCTVERSION 0,0,0,1 #define VER_PRODUCTVERSION_STR "0.0.0.1\0" #ifndef DEBUG #define VER_DEBUG 0 #else #define VER_DEBUG VS_FF_DEBUG #endif VS_VERSION_INFO VERSIONINFO FILEVERSION VER_FILEVERSION PRODUCTVERSION VER_PRODUCTVERSION FILEFLAGSMASK VS_FFI_FILEFLAGSMASK FILEFLAGS VER_DEBUG FILEOS VOS__WINDOWS32 FILETYPE VFT_APP FILESUBTYPE VFT2_UNKNOWN BEGIN BLOCK "StringFileInfo" BEGIN BLOCK "040904E4" BEGIN VALUE "CompanyName", "example.com" VALUE "FileDescription", "demo" VALUE "FileVersion", VER_FILEVERSION_STR VALUE "InternalName", "demo.exe" VALUE "LegalCopyright", "Public domain" VALUE "OriginalFilename", "demo.exe" VALUE "ProductName", "demo" VALUE "ProductVersion", VER_PRODUCTVERSION_STR END END BLOCK "VarFileInfo" BEGIN VALUE "Translation", 0x409, 1252 END END ///////////////////////////////////////////////////////////////////////////// // // Icon // // Icon with lowest ID value placed first to ensure application icon // remains consistent on all systems. IDI_ICON1 ICON "demo.ico" /////////////////////////////////////////////////////////////////////////////

More info on the VERSIONINFO resource can be found here.
We use the resource compiler windres, and then the gcc compiler.

Compile for 64-bit:

x86_64-w64-mingw32-windres demo.rc demo-resource-x64.o x86_64-w64-mingw32-gcc -o demo-x64.exe demo-resource-x64.o demo.c

Compile for 32-bit:

i686-w64-mingw32-windres demo.rc demo-resource-x86.o i686-w64-mingw32-gcc -o demo-x86.exe demo-resource-x86.o demo.c
