This is something that I built to find hidden packages On somebodies whmcs

It works by testing each pin ID Starting from number 1

This will find all packages including hidden ones and save the URL to a txt file, if successful, So you can review them later.

This might not work on all websites but a majority it will

But with this handy little tool you will be able to find hidden packages and purchase them, And get the files if need be, Also some hidden packages there is no price
