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
