I was born and bred in Hungary. During my university studies I started to deal with the ethical hacking, I did CTFs, and I've been interested about the secrets of exploit development. I wrote my thesis about a glibc vulnerability, which was a stack based buffer overflow. I wrote a working exploit to it, and I used ROP chain to bypass the NX memory protection. After my studies I started work for a German company as penetration tester. I did the OSCP and OSCE certifications. The OSCE was not necessary for my work, but I interested about it, so I did it. Some notes about my hobbies: I like drive, and I have driving license for everything( incl. planes ( PPL(A))). I like sports like running, go to the gym, kayaking, canoeing etc.
