Kor Adana knows how to hack your computer. He knows how to write code that could exploit all your deepest, darkest data. With a laptop and an internet connection, he could cause a lot of companies some serious security headaches.
Mercifully for us all, Adana is one of the good guys.
A former cyber security expert, he's moved his way from coding computer screens to writing for the small screen, now working as technology consultant and writer to the wildly successful TV and Amazon Prime series Mr Robot.
We asked Adana what he thought the next big 'hack of century' would be, the major misconceptions of computer security, and for his advice on making sure your computer is super secure.
Mr Robot will be available on Amazon Prime Video from 14 July
How would you define a "hack"?
"I would say a hack is using either a system, a piece of software, a piece of technology - or manipulating a human - in order to achieve a goal that isn't directly apparent. Using systems in a way to achieve some other goal, some other purpose.
"Relating that back to the way film and TV has portrayed it, it's usually just someone dropping lingo or trying to make it interesting with flashy cheesy graphics, making it look like almost a video game - a sequence with a nerdy guy in the corner who can type really fast and spit out exposition about what he's doing, and even that exposition doesn't make sense.
"I think the real world of hacking is inherently dramatic and I think that those writers and producers and directors that came before us either didn't understand it, didn't take the time to understand it or they felt that it was boring."
