I was trying to search for this, but could not find the answer anywhere - apology in advance if already answered.
I have a Linux desktop installed on a thumb drive, which I keep in my pocket. This way, if I need to access my bank (from a public computer and otherwise), I boot from it so I don't need to worry about key loggers. The file system is ext2 and not encrypted. I normally leave my Google account (Gmail, etc.) logged in Chrome, so when I use it next time, it goes directly into my Gmail without asking me for password. If my thumb drive gets stolen, I assume it can be inserted into another computer's USB port and the ext2 partition mounted to access the files without needing my Linux password.
Question: Assuming I have the latest Chrome installed, would the attacker be able to access my Gmail by copying my cookies (or whatever other way Chrome uses to keep my password between the shutdowns)?
