Shadow Brokers Group Leaks Stolen National Security Agency Hacking Tools

PERLROTH: We don't know who they are. They first appeared last year online. It was a group. They call themselves The Shadow Brokers. And they said that they had managed to steal classified National Security Agency secrets. And initially they just offered to sell the secrets to the highest bidder.

But eventually they just started posting some of that stolen data online. And just this past April, they dumped a number of classified hacking tools that belong to the agency - dozens, actually. And so for the past two months, we've started to see an increasing number of attacks using those tools. As far as their identities, we - there were some initial theories that it might be Russia. But more recently, the leading theory appears to be that it might have been an NSA insider.
