Hi,
The issue lies in that if the user gets the memorable information incorrect they are asked for the same character positions (e.g. 1, 7 and 9 again). This continues forever, basically making the memorable information pointless because it will not take much to brute force it.
not correct. after about 7 attempts the account is locked out at the username/password part
No attempts have been made to contact LloydsTSB regarding this matter as I was unable to locate contact details and it is not that severe.
http://www.lloydstsb.com/security.asp is a good starting point anyway, LloydsTSB are moving to 2-factor authentication and most of their customers should have their online backing upgraded by the end of this year http://www.vnunet.com/computing/news/2151425/lloyds-tsb-trial-wipes-online alan _______________________________________________ Full-Disclosure - We believe in it.
