Trion sent out to users emails telling them that their was a security breach the other day. They say they do not believe credit card information was compromised, whoever "do not believe" and "was not" are totally different things. So players are left wondering the full extent to this. They have not told anyone how this happened, or how they fixed it either. They do say that security experts are looking into the full effect of this damage.
I have already, and would recommend others immediately change their personal credit card info so they wont have any problems. Remember sony said the same thing...
- Update trion has said that they have no information that shows peoples credit cards where vulnerable.
