Finding VBA signatures in .docm files

Last week I researched how to detect signed VBA code in Word .doc files.

For .docm files, it's easier. .docx and .docm files are actually ZIP files, and a .docm file (Word document with VBA macros) contains file vbaProjectSignature.bin when the VBA code is signed.
