Twitter gets targeted again by worm-like phishing attack

From InfoWorld: Twitter users have been tricked into divulging their login and password details to a Web site that then spammed their contacts.

The culprit is a Web site called TwitterCut. Some Twitter users began getting a message that appeared to be from one of their friends and included a link to the TwitterCut Web site. The message implied they could gain more Twitter contacts by following the link.

At one time TwitterCut looked quite similar to the real Twitter login page, said Mikko Hypponen, chief research offer for the security vendor F-Secure.

If a person entered their login details, TwitterCut would then send the same message via Twitter to all of the victim's contacts, a kind of phishing attack with worm-like characteristics. No malicious software is installed on a user's machine, Hypponen said.

Although TwitterCut probably holds the login details for many accounts, it doesn't appear those accounts have been used to spam out links to more dangerous Web sites.
