Twitter users have experienced another phishing attack during the week of Feb. 22nd 2010 according to security firm Sophos. This attack featured a headline "This you????" following a false Twitter login page. Should a user login to the false Twitter page, then the attackers would have the login credentials to access that users account and expand their phishing attack base. The distribution radius was exceptionally wide due to third party services such as GroupTweet, which allows mass Tweets.
