Twitter counters onmouseover security flaw

Twitter Mashable Wall Street Journal CNET post Daily Mail

The Twitter website is being widely exploited by users who have stumbled across a flaw which allows messages to pop-up and third-party websites to open in your browser just by moving your mouse over a link. Messages are also spreading virally exploiting the vulnerability without the consent of users. It appears that in Sarah Brown's case her Twitter page has been messed with in an attempt to redirect visitors to a hardcore porn site based in Japan. That's obviously bad news for her followers - over one million of them.
