ThemidaUnpacker

A Python 3 tool to dynamically unpack executables protected with Themida/WinLicense 2.x and 3.x.

Warning: This tool will execute the target executable. Make sure to use this tool in a VM if you're unsure about what the target executable does.

Note: You need to use a 32-bit Python interpreter to dump 32-bit executables.

Features

• Handles Themida/Winlicense 2.x and 3.x
• Handles 32-bit and 64-bit PEs (EXEs and DLLs)
• Handles 32-bit and 64-bit .NET assemblies (EXEs only)
• Recovers the original entry point (OEP) automatically
• Recovers the (obfuscated) import table automatically

Known Limitations

• Doesn't handle .NET assembly DLLs
• Doesn't produce runnable dumps in most cases
• Resolving imports for 32-bit executables packed with Themida 2.x is pretty slow
• Requires a valid license file to unpack WinLicense-protected executables that require license files to start

How To

If you don't want to deal the command-line interface (CLI) you can simply drag-and-drop the target binary on the appropriate (32-bit or 64-bit) ThemidaUnpacker executable (which is available in the "Releases" section).

Otherwise here's what the CLI looks like:
