Reversing Google Drive and other goodies ;)

Reversing Google Drive

1. Download Google Drive and install it (or use 7-Zip to extract the resources from the .msi file).

2. googledrivesync.exe file is "fat" and looks interesting, right?

3. Download a special version of PyInstaller.

   $ git clone https://github.com/kholia/pyinstaller.git -b AntiDrive
   
   $ cd pyinstaller
   

4. Extract stuff from googledrivesync.exe file.

   $ python utils/ArchiveExtractor.py googledrivesync.exe

5. De-compile the bytecode files using uncompyle2.

   $ uncompyle2 output/common/worker.pyc
   pass
   

   ;)

5. Study the soure-code, find bugs and make Google Drive better!
