The US military has procured a "spy software" which will let it secretly manipulate social media websites, like 'Facebook' and 'Twitter', by using fake identities to spread propaganda, a media report said.

The US Central Command has purchased the US dollars 2.7 million programme -- developed by San Diego firm Ntrepid -- which allows one military user to create multiple personas on internet and engage in extended online communications with terror suspects, 'The Washington Times' reported.

In fact, the programme is aimed at helping troops create and maintain realistic online personalities that would persuade extremists to allow them into chat rooms and bulletin boards by creating the appearance that they are logging on and posting messages from anywhere in the world, the report said.
