Today yet again seems like twitter is affected by XSS (cross-site scripting) attack after the recent mouse over script attack on twitter.
As per information – A malicious link is making the rounds that will post a tweet to your account when clicked on. Twitter has disabled the link, and is currently resolving the issue.
Still avoid clicking any link which begins with WTF, those who have clicked that link will send out Tweets saying “I Like Anal Sex With Goats.” This Tweet is followed by another one that says “WTF” and includes a link.
Please Note: It looks like this is happening across third-party clients and on Twitter.com
Twitter is working on this issue, it will be resolved soon..stay tuned we will keep you updated on this page about this issue.
