There's a bit of controversy on the web at the moment as a group that is called UGLegion claims to have hacked Origin. To back that up they posted a snippet of info with their results on pastebin and then uploaded a downloadable text file containing close to 1.2 million user accounts including email address and passwords.
The list contains email accounts from Google, Microsoft (Hotmail and Live) and Yahoo! and other webmail services. It appears that every user in the list had registered an origin account using all four main services and in some cases variations of the same username are visible.
