Twitter users warned of onMouseOver hackers

Micro-blogging site targeted by Javascript hackers

Warning all users of micro-blogging site Twitter

Micro-blogging site Twitter has seen a security flaw in its system exploited as hackers enable third-party websites to open within user's browsers just by hovering or passing their computer’s mouse over a link.

The security flaw, which uses a chunk of Javascript coding known as ‘onMouseOver’ allows you to be redirected to other sites without having to click a contaminated link. High profile victims of this crafty hack so far have included the former Prime Minister’s wife Sarah Brown whose Twitter feed was targeted to link directly to a Japanese porn site.

Despite claiming that the flaw is “innocuous”, security firm Sophos has recommended that, until the Javascrip code has been blocked by the social networking site, all users use a third-party client to access Twitter.

Twitter users are also advised not to click any onMouseOver links or links that contain blocks of colour. A full safety warning video, which can be seen below, has been created by Sophos to target these points are potential harm.
