Tutor: Nick Bruinsma

Nick is ethisch hacker bij The S-Unit.

Met zijn achtergrond als developer voert hij graag white box en mobiele app pentesten uit.

Het lezen van source code vindt hij een leuke uitdaging om kwetsbaarheden te vinden die vanaf een black-box perspectief niet altijd even makkelijk te vinden zijn.

Daarnaast is hij ook graag deelnemer (of organisator) van CTFs. In zijn vrije tijd studeert hij Braziliaans Portugees, nog meer hack-technieken of willekeurige trivia om te kunnen winnen met 30 seconds.
