The movie Blackhat (2015) shows professional hackers sabotaging an atomic reactor and the stock market, as well as counterhackers trying to get on the blackhat's trail, finding out their identity.
As a relative layman in the field of hacking, I got the impression that the movie was trying to be very accurate when it comes to the processes involved in hacking and tracing a hacker. At least it seemed a lot closer to reality than most other films before it.
How realistic is the hacking process depicted in the movie? Are the commands used onscreen actually meaningful and authentic? Or did they make up things to increase the dramatic effect? If so, which?
Was the movie counselled by actual hackers of some sort, to increase authenticity?
