First off, I don't know if this is the right forum to post this but if its not please direct me to the correct one.
Today I discovered my account was compromised. Here's the chain of events.
I typically use the Live ID associated with this account to manage my company's business relationship with Microsoft via Volume Licensing Agreements (VLA). The last time I signed in was the first week in Jan, 2012 to get some product keys. Today I had to update our agreements with Microsoft and attempted to sign in. The password I used did not work and after some time I was able to get it reset on my own.
With lots of suspicion, I did some poking around and noticed several interesting emails one of which was a survey from Xbox support about my recent call to them. From this I can extrapolate that the hacker used social engineering techniques to get the support staff to get the email reset for them so they could assess this account.
I also notice two email confirmation for Microsoft Points purchases - 4000 and 6000 points. Lastly, there was an email for an EA Master account registration.
I also went to the billing website and noticed a credit card attached to my account. At no time did I ever attached a credit card to my account and I suspect it belongs to someone else. Furthermore, I do not recall ever creating an Xbox Live gamercard with this account but I am not sure about this part. There is a name that is not mine in the billing info on the billing website.
My concern is that I don't want someone coming after me for fraudulent conduct and I would like xbox live to thoroughly investigate this issue and involve the authorities as necessary. I will happily provide a cell phone and/or home phone if someone in the U.S.A. would like to talk to me about this.
