The Register has posted an article about a new worm that spreads on Twitter. Infected accounts sends messages to other users with a link. The message looks like: rofl this you on here? http://videos.twitter.secure-logins01.com

If a user clicks on the link, the webpage will require him or her to login. Then, their account details would be stolen.

Similar things have happened in the past in Twitter. Those that was hit with the scam are advised to change their password or contact Twitter support if they are already too late.
