There's a hacker inside Asiasoft Thailand

I think it's too much of a risk to be an inside job, but I could be wrong. I'll hope that the players don't get royally screwed over anymore though.

Inside job would be less detectable as the hacker could easily fudge log files, delete data, alter files, and forge anything needed to cover his/her tracks. Outside job would be more detectable as the administrators could easily find out who accessed what, when, and from where.
