Sophisticated Gmail Hack

Poor choice of title. Someone's Gmail account got hacked and he has no idea how - nothing to suggest Gmail is at fault.

Edit: From the OP on the Reddit thread:

------

This account password was shared with a few other accounts (Netflix) I usually access via http or IMAP (mobile devices) I access the account via multiple sources usually: * 3 Work computers that I am the primary user for (they are all secured by a separate work log-in) * iPhone 3Gs * iPad1 * iPhone 3Gs * Laptop & desktop at home that only I use

Chrome is my primary browser on all computers I use and it maintains my password through an account sync.

I don't think I've typed my password into any other page - i'm usually automatically logged in via Chrome's autofill.
