Authentication 7

Attacks should be prevented from being able to obtain valid account credentials by using the application in an unintended manner. This includes credential cracking (identifying valid login credentials by trying different values for usernames and/or passwords) and credential stuffing (mass log in attempts used to verify the validity of stolen username/password pairs).

NB: This card relates to passwords. See AT 4 for the similar user name attacks.

How to play?

Cecilia can use brute force and dictionary attacks against one or many accounts without limit, or these attacks are simplified due to insufficient complexity, length, expiration and re-use requirements for passwords
