Hello! I'm Celil and I describe myself as a cyber
security enthusiast. I'm working as Senior Director of Software Engineering at SonicWall.
My interest in hacking and cybersecurity actually began in the late 90s
when I was just a child. I'm talking about the days when we
connected to the internet with dial-up modems and eagerly tried to
learn something on IRC channels. During those years, I got to know
various individuals (Hurby, b4r0n, AhmetBSD, N4RK07IX, CTR) on various forums and IRC
channels, and developing myself with their guidance eventually
turned my curiosity for hacking into a profession.
In fact, I graduated in Economics from Marmara University. While I
dabbled in hacking as a hobby, focusing on areas like reverse
engineering and vulnerability research, my career goal was to become
a successful academic in the field of Economics. However, fate had
other plans for me. During my university years, I discovered many
0-day vulnerabilities in closed-source applications and I sold them
to vulnerability purchase programs like iDefense, ZDI, SSD etc.,
and earning what I considered to be handsome sums fueled
my passion for the field.
In my second year of university, I attended as a speaker to a
hacker conference held in Poland where some prominent figures in the
scene were speaker too. This experience completely changed my career plans.
I decided to put my academic goals in Economics on hold and focus on cybersecurity, specifically
I believe that I have contributed significantly to the cybersecurity community in Turkey by making
valuable contributions in the field of vuln-research/exploit-dev
relative to the time, organizing Turkey's first international hacker
conference called NOPcon, and conducting various volunteer training
sessions to increase interest and awareness in this field in Turkey.
I can also say that throughout my career, I have led many satisfying
and innovative cybersecurity initiatives. I consider my most significant
achievement to be the founding of TRAPMINE in 2016. Despite challenging conditions
and without much capital support, we developed a successful product that
could compete with many major vendors. Ultimately, we achieved a successful exit to one of the largest and most reputable cybersecurity vendors in the US in September 2023.
I can say that I have expertise in the fields of Reverse
Engineering, Vulnerability Research, Exploit Development, and SCADA
Security in the cybersecurity domain. Throughout my career, I have
enjoyed reading assembly code, debugging closed-source applications
with WinDbg, and hunting for vulnerabilities. These skills and
experiences have contributed significantly to my career in the
Additionally, I really enjoy attending cyber-secuiry conferences around the world either as a speaker or listener.
Some of the conferences I have been a speaker includes:
- Power of Community 2015, South Korea
- Code Blue 2014, Japan
- Swiss Cyber Storm 3 , Switzerland
- CONFidence 2010 , Poland
- Defcamp 2014, Romania
- Kuwait Infosec 2013, Kuwait
- NOPcon , Turkey
