My xbox live account was hacked the other day. Since i had my credit card on file to pay for my xbox live Gold, The hackers used my card to make a grand total of 35 purchases, totaling in over 60$ worth of goods. I immediatley changed the password to my account and manage to get a hold of it from the guy who had purchased my info.
Apparently they find your information, purchase several things using your bank account, and then sell it to someone across the globe on some kind of trading website similar to ebay. (They guy who purhcased my account tried contacting me after i changed all of the info and passwords)
I called microsoft in order to refund my money, and the service rep was very helpful, but as i looked more deeply into the matter, i discovered that apparently this hacking is far more widespread than i expected. Using an exploit in fifa 12, users accounts are hacked into, leaving a trace of 3 'ultimate teams' achievments in fifa 12.
There are hundreds if not thousands of people here who have had the same problem as me, and it even prompted a main article on IGN
I have never fallen for any internet scams and i have no idea how they were able to figure out my information, but now i am locked out of my account and have no access to my username for at least a month while they try to figure out what happened . Worse yet, apparently there are people who never get access back to their accounts, and even half a year later are still waiting.
If you have a credit card on file with xbox live Gold then change your passwords and be careful because it can happen to anyone !!
