Guessable Usernames and Passwords

Did they or didn't they (share user credentials)? Abuse of copyright? Bad information security practices? Breach of contract? Poor authentication controls? It's all going to court soon.

The case is explained in a Reuters blog posting Financial Times finds new way to save newspapers and in SC Magazine's article FT sues Blackstone Group for sharing premium account login details .

It seems FT.com doesn't enforce password complexity:

... The court documents list the username as "theblackstonegroup" and the password as "blackstone"...

Therefore, I suppose it could be argued that the username and password were guessed and used by third parties. Since it's probably not difficult to predict other FT.com clients, this information gives clues to what other login credentials might be. Known usernames are an essential starting point for breaking into web applications and when combined with passwords which can be broken by brute force, mean there is very little protection here.

A report by Pinsent Masons Firm sued over multiple use of individual's FT.com login also suggests that a discussion on "unique cookies" will also come into the case. Let's hope the court takes time to understand the possibilities for use and abuse.
