The reality of conflict (not war) in the cyber domain -- Sony is now reported to be launching DDoS attacks against the hackers attempting to distribute its confidential documents:
Sony has launched a counterattack against people trying to download leaked files stolen from its servers after a massive hack.
Re/code is reporting that Sony is using Amazon Web Services to rent cloud computer power and aim traffic at sites offering the company's files for download.
Sony's attack is actually similar to a tactic used by cybercriminals. When hackers want to take down a website, they point huge amounts of internet traffic at it. That's called a "distributed denial of service" attack. Sony is essentially doing the same thing to fight back against hackers.
