The Web site for Australia's Big Brother reality show is posing a security risk for fans who log in to access special features. 

This follows an earlier compromise whereby visitors were redirected to a hard core pornography site.
The latest technical hitch exposes the log-in details, as well as names, e-mail addresses and phone numbers, of fans who have signed up for both free and paid-for Premium content.
People who have signed up for the Premium service are also concerned about the safety of their credit card details. This section of the site has been disabled until the security breach is fixed.
A sign posted on the Behind Big Brother sign warns users not to sign up or log in until further notice.
