Nulling a php project

Hello all

I'm pretty new to this so I hope I can count on some tips to get me in the right direction.
For now I'm trying to null a php project that has no encrypted files as far I know right now.

After some Googling I came across some interesting stuff.
So I did a http sniff to check for callbacks using httpry.
Strange thing is I couldn't find any callbacks to another server.

Searching for the domainname or message in the js popup pointing out the script has no license also went without result.

Can someone put me on the rails?

The script may connect to another domain / ip than the project page to verify license.
The code may contain function / methods that open connections.
Urls could be obfusucated to make detection more difficult.
License verification might not run on every request.

There are enough forums on the web dealing with this kind of stuff.

Anyway I'm not a fan of nulled Software. You want to earn money, so why rip others of theirs?
