UnZip

Challenge

DESCRIPTION
UnZip me!

MD5("Un.Zip"): 8C2E6C30CB4C1838768F658B9E5E9065

ATTACHED FILES
Un.Zip

Solution

We have a password protected ZIP, but its file structure looks a little strange through XXD.

Looking at it, there is a ZIP file header and PNG file header.

Extract using python, split on the PNG file header.

extract_PNG.py

Alternatively, using foremost, it extracts the file out too

 # foremost Un.Zip 
Processing: Un.Zip
