Twitter has a big problem. A new security design flaw is now being heavily exploited. Here’s what you need to know now.
First, don’t use Twitter. Third-party programs, such as TweetDeck, twhirl, and Twitterfall seem to be immune to the problem.
If you are using Twitter, the security hole will “appear” to be a block of black text. What it actually is though is a tiny JavaScript program. If you even just place your mouse over the text, no need to click, you’ll activate the program. This “mouseover bug” can then launch potentially malicious pop-ups, send you up to third-party sites, or even send out more tweets, thus spreading the problem.
