I have been working as a penetration tester/security researcher for 6 years now. I started at a small consultancy called kancellar.hu and had the pleasure of working for local branches of almost all major international companies in Hungary. Following this, I moved on to work at Vodafone Global as part of the team here in Budapest. Hacking ATMs was something I always thought of as the ultimate challenge, mostly because of the secrecy surrounding them. It is also something that is not easy to get into since most companies who own ATMs tend to guard their secrets well. But thanks to a few very helpful people I managed to get a chance at doing this for my master’s thesis. In my free time I attend conferences, take part in CTFs and occasionally give lectures and presentations. My favorites are reverse engineering and hardware hacking.
