Recently a few people in the modding scene that I know found a exploit in the 'Guide.MP.Purchase.xex' and 'xam.xex' that allows users with hacked consoles to edit a few offsets in memory and POOF, you now have $1337.00 in MSP spoofed to your account. Luckily this has been kept private for a few dashboards but the admin (Domo) of Xbox Live Hammer recently added this to his online server. Now anyone running the XBLHammer online files and that purchases online time from him will have spoofed Microsoft Points.
Luckily this exploit is only available to people with hacked consoles (JTAG, RGH-1, RGH-2, R-JTAG) but this has been a problem for Microsoft.
Microsoft is now aware of the issue and will more than likely be issuing a system update in the near future resolving this exploit.
What are your guys' thoughts?
