Who Am I - Kein System ist sicher (2014)

This gem is just brilliant. A subversive hacker based film that is not the easiest to make very cinematic but Who Am I works out a way to do so. Benjamin is a genius hacker trying to reach the top following his idol's steps. But MRX. The last one belongs to FR1ENDS who are known to be a group of hackers employed by the Russian Mafia and things get complicated as Ben and his team, CLAY, try to make him recognize their work. This encourages them to focus on two actions: to discover the identity of MRX and actively work to stop FR1ENDS. Little do they know, this will all culminate into one massive hack that is more "social engineering", than it is limited to computer hacking. The acting, scrip and action complete a creative, stylish, and quite entertaining film that you will remember for a long time.
