Hacker claims to be selling stolen NSA spy tools

On Saturday, a load of computer code -- whose purpose is to break into other computers -- was leaked to the public by an anonymous entity called "The Shadow Brokers."

The same mysterious entity also promised an upcoming "cyber weapons auction" -- the digital equivalent to putting stolen military missiles up for sale.

The gang claims the stolen hacking tools were developed by "the Equation Group" -- a spying entity widely thought to be the U.S. National Security Agency and spying departments from four international allies: Australia, Canada, New Zealand and the United Kingdom. Together, that group is called the "Five Eyes."

Computer security experts worldwide now worry that sensitive NSA spying tools are accessible to common criminal hackers.
