Reformed hacker Jacques Erasmus from security firm Prevx takes control of a computer by infecting it with trojan software.
The infection allows him to view whatever is on the victim's screen and record his key strokes.
Jacques Erasmus' company downloaded the trojan for research purposes.
The trojan and bank accounts used in this video are real.
The 'victim' in this simulated attack gave permission for his laptop to be infected for the filming.
