Use Excel vulnerabilities to hack Excel protected worksheet passwords

Use Excel vulnerabilities to hack Excel protected worksheet passwords

This experiment is to exploit Excel to protect worksheet passwords by exploiting the vulnerability of Excel to compress files.

First we build a Excel table and then set Excel to protect the worksheet password and save as
