RUMOR: Exploit Results In "Theft" of $1.2 Million In Xbox Live Codes from Kotaku

Yesterday, a forum user on website The Tech Game posted a way for people to scam free points for use on Xbox Live. By the time Microsoft found out and shut it down, over $1 million in codes had been "stolen".
User "Dark" is the author of the post explaining the exploit, which was able to generate authentic download codes for Microsoft Points on Xbox Live, essentially letting people get money for nothing.

A report on Save & Quit says that though it only took Microsoft a few hours to discover this exploit and put a stop to it, by the time this took place around $1.2 million in Microsoft Points had been hoisted by those fast enough to get in on the scam.

We've contacted Microsoft for confirmation of this, and will update if we hear back.

For those using US/EU prepaid codes 1600, 2100 ms points besure to activate them ASAP. If anything goes wrong, you need to contact MS to get a new set of codes.

I'm sure they can track and eventually ban those people. I have 1600MS points on the way from PlayAsia but not sure when arrive, hopefully no problem .. will report back then.
