"They cross match accounts, especially accounts with 'cash' on tap, such as
built up purchase points, or accounts with credit card info saved.
They then use those to buy agnostic value items such as FIFA cards, then
transfer those cards to another account and sell them.
Essentially they're mining accounts for cash. I know, I was victim to it as
well. My 360 account and Origin account were compromised on the same day,
both using unique passwords but the same email address."
