Twitter Closes Up Loophole That Sent Unwitting Users To Potentially Dangerous Sites

Twitter patched up a security gap that sent users to other sites when they moved their mouse cursors over links. Using a JavaScript function called onMouseOver, spammy marketers drew in unwitting customers to their sites without them having to click.

The exploit opened up unauthorized pop-ups and sent people to less-than-safe-for-work sites. But thankfully Twitter has tamed the beast. A spokesman for the social networking platform told Mashable “This should now be fully patched and is no longer exploitable.”

      Do you ever have any problems when you use that with ajax-ified sites like google?

      • jessjj347 says:

        Nope. Also, I can allow scripts on a page individually (either temporarily or permanently).

          This. I use noscript because unneeded javascript can grind my internet to a halt due to the weak signal I pick up on my laptop at work. I can see what sources are implementing the scripts and choose to allow or disallow individually. For example, is always allowed, but google-analytics, facebook, fbcdn, addthis, and sitemeter are all blocked on just this page alone. Noscript + Adblock Plus = Holy shit my internet works! People get pissy about blocking ads, but if the site just won’t load, I still wont view the ads. And, I have no money to spend, so i won’t click even if i see them.

    I like how Jimmy Fallon worded it last night. “There’s a loophole on Twitter that leads its users to porn sites.” Then he went “There’s a cool new feature on Twitter that leads its users to porn sites.”
