The social media site Mashable reported that the bug was caused by a security flaw on Twitter.com. Users are unknowingly being directed to third-party websites simply by scrolling their mouse cursors over offending links.

Users were advised to use Twitter through third-party clients, such as TweetDeck and HootSuite, instead of on Twitter.com.
