I just attempted to called Blizzard once I got off the phone with my Bank's Fraud unit. I made a purchase of the "remote" app using my bank card, as a result, my bank informed me that someone has been trying to make other purchase using my card ....following me buying the "remote app" online, and that they have frozen that account (once they saw the strange stuff going on.)
Therefore, this ticket is designed to let you all know that there is a BREACH IN SECURITY IN REGARDS TO REMOTE APP. CHECK your bank accounts!!!! Thanks goodness that my Bank was on it.
This is not correct and is a misunderstanding of the process by which bank fraud occurs. There is nothing in either the WoW Mobile Armory or the Battle.net Mobile Authenticator that could possibly be tied to a bank account, nor does it act as a back door of any sort.
You entered your credit card information online using a web browser on a computer that we cannot make any claims to being secure. We use a secure site, but if your credit card info is stored anywhere in the browser's cach or you're choosing for the browser to "remember" the info, that may be the reason for this.
If you have a trojan or a keylogger on your computer, you could be unknowingly providing this data directly to a hacker or bot.
Please, I urge you not to make your conclusion that it's the app because otherwise you may erroneously remove it from your mobile device, thinking you thwarted the breach in security, when the breach is in reality coming from an entirely different source.
We don't merely put out applications hoping they're secure, we have a security team monitoring our system 24 hours a day, 7 days a week.
