Man in the browser attack

Recently I heard of the man in the browser attack and thought it was interesting.  This is malware that is installed in your browser (as an extension for example), and silently waits for you to do a bank transfer.  When you do it can simple change the to account and routing numbers you submit to that of the attacker.  Everything looks fine to you, and wire transfers already take days to process.  Things like strong passwords and 2 factor authentication won't help since you are logging into your real bank's website.
