You may discover your computer was overtaken by a malware and will ask for money to clean it up or you will lose your data. May be this will start uploading all the data your have in you system. You just do not know. If something seems fishy then better to stay away from it.
Exactly like what you said, This is so fishy for 2 reasons:
1- This script should be not so cheap like that, he should use it to gain more money than he put on satoshibox.
2- It's so risky to trust new members here in the forum.
Even if you decided to buy this script, it can be full of malware and maybe you will lose your PC and your data will be hacked because of it.
