A worm has spread over both the web version of Twitter and third-party applications, apparently. What happens is the following – someone (or more than someone) tweets ‘i like anal sex with goats’, followed by a ‘WTF: [link]‘ tweet. This will happen to you if you click the link, too. This isn’t the first time a security flaw has taken over Twitter, but it looks like it’s only a simple joke.
Don’t worry, the exploit has been fixed.
