WHOAMI
Cyber security researcher breaking and defending critical infrastructure.
My name is Halit, and I have been using computers since I was three years old. It sounds unlikely, but I have a photo to prove it. I found my first vulnerability at eight, in a military computer, and it let me log in without authentication. My reward was an orange flavored biscuit. I have been chasing that same feeling ever since.
These days I work as a Mission Critical Security Engineer, focused on protecting key infrastructure across Europe and the essential systems that quietly keep daily life running. The job pulls from a background that grew in several directions at once: malware analysis, digital forensics, penetration testing, and threat intelligence. I hold an MSc in Computer Science, and I have spent years putting that theory to work in real operational engagements.
On the offensive side, I have run penetration tests against critical infrastructure and just about anything with a chip in it, from aircraft to televisions to whatever IoT device happens to be in reach. On the defensive side, I have led high profile incident response efforts and worked complex criminal investigations, often alongside law enforcement on cyber criminal manhunts. I also produce actionable intelligence on state sponsored actors and APT groups.
I like problems that do not have obvious answers, and I tend to approach them by poking until something gives. That instinct shows up in CTF competitions, hackathons, and bug bounty programs, which are still where I do some of my favorite work. My certifications include the CISSP, OSCP, OSCE, and Certified Threat Intelligence Analyst.
