Trusteer Rapport
Once upon a time I logged onto a customer's router only to be confronted with an alert from Rapport informing me that I had entered a sensitive keyword. I quizzed the customer about this and he told me that he used the same password for on-line banking. Glossing over the prudence of sharing passwords for the purposes of this comment, knowing this idiosyncracy meant that a hacker would know that the Rapport icon in any browser is a great invitation to run a dictionary attack. I would hope that that vulnerability has now been fixed.
