Today I received a PM with the item from Envato.
The product I wanted was:

https://www.virustotal.com/There were 0 infections detected, nor did my anti-virus scanners (ESET) found anything.
The scan with rootkithunter and Clamav for PHP exploits was negative aswell.
The script seems to work and is delivered with an installation guilde, which let me believe Yurinachan bought the script as he described in his service.
I can't say anything about support or updates (need to test some settings), but the service I got was legit and it's exactly what he is offering.
Either way it never harms to check scripts with virustotal and use an escrow for the first few sales.
Other then that Yurinachan provided me with the script I was seeking.
