Hello, I’m Ryan Kozak and I’m a security engineer and recovering web developer living in Sacramento. I moved to Northern California in December of 2013, and with the exception of a brief few years living in Memphis, I spent most of my childhood on the Central Coast in a little town called Santa Maria California.

This is my blog, and sometimes I’ll post CTF writeups, other things related to computer security, privacy, web development, and maybe some rants here and there. This is my home page, so it’s kind of whatever I want, and I don’t want it to be too formal. If you’d like to talk please check out my contact page, I’ve got a few email addresses on there.


I’m an avid Linux user and an advocate for FOSS. Currently I work as a security engineer in the threat and vulnerability management space, primarily in threat detection automation. In times past I’ve worked as a full stack developer, mostly using PHP and frameworks like Laravel, CodeIgniter, and the dreaded WordPress CMS. I don’t touch most of those anymore (unless they appear in a CTF), with the exception of Laravel, which I still enjoy using for some personal projects like MapMoto.

As of 2021 I’m co-leading the OWASP Sacramento chapter, which has been a very rewarding/challenging experience.

When I’m not on a screen I love riding my motorcycles (Motocross and ADV), cooking, traveling, or getting out into the mountains locally. I’m always trying to remind myself that computers aren’t actually real, and that there’s a whole life out side of screens. That is why you won’t find me blogging about things that aren’t too computer related, it ties everything together too much to post everything I do.
