RE: SPAM-LOW: passw0rd trial limit

["Mohsin Ahmed" <mohsin () catcointernational com>]

Hey,

Disabling users is a kind of control that many companies use as
countermeasure for brute force attacks.

Can any one tell me, what are the other controls to prevent such kind of
attack?

Subject: SPAM-LOW: passw0rd trial limit

hi

i am trying to pen test a web site

site has a login page and all the usernames are known
the passw0rd length is fixed and 6 characters long

i think with a brute force attack it wold be easy to login as any user,

but the problem is when a user enters wrong paaw0rd more than five times
he/she can only login for aboout 2 hours later

how this obstacle can be overcomed do you have any idea?

by the way remote server accepts another user login wehther you have 
exceeded trial limit or not
so i think it is not related with the ip filtering
