I came across a username at a new customer I was not aware off: "pix".(I felt like an Idiot looking through "show run all" not seeing the user after 5 years of descent asa/pix experience)
While I am usually using username/password/priv-level and aaa authentication on my ASA configurations, this customer is using a user "pix" which is invisible in the "show run" and "show run all" command or even the "more system:flash" command. IMO it is a rather bad practice to use a user which would not survive any current configuration backup mechanisms or even worse open a firewall with a default user after some kind of configuration recovery/reset.
Anybody any Idea why people would use this undocumented user - why there is a user on the Cisco ASA which can be used to login with - or where in the world this user is stored with its password? - Is this a kind of TAC backdoor to lost passwords?
