Re: passw0rd trial limit

hi

one possibility could be to cycle through the usernames as well. so
that you can try much more combinations.

or if your bruteforcer can detect things like that you could let it
try 5 logins with one username and then try 5 logins with the next
username. if the site has enough users you could spend the 2(?) hour
blocking time for each username with tries on another username.

this works only if there is no ip filtering, which is like standard
when blocking, or not?

are there other ideas?

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
