Zion Leonahenahe


Hacker turned Security Researcher



I’m a Ph.D. student at Arizona State University studying Computer Science with a focus on Systems Security. Online, I go by the handle mahaloz. I was born and raised on the Big Island, and I’m proudly Native Hawaiian.

I research with the security lab SEFCOM at ASU under Dr. Fish Wang and Dr. Yan Shoshitaishvili. My research interests are in program analysis, with an emphasis on binary analysis, reverse engineering, and decompilation. A full listing of my publications can be found on Google Scholar. Research prototypes and tools from these works can be found on my GitHub, including our decompiler angr decompiler.

I hack with the epic team Shellphish, of which I was a previous co-captain. We play in hacking competitions called CTFs, organize competitions, and develop new tools for the community. Using my experience on the team, I’ve created a variety of educational materials found in pwn.college, ‘Ike, and lectures presented for the ASU Hacking Club.

If you’re looking for technical-oriented content, like CVE announcements, writeups, and research musings, then take a look at my technical blog mahaloz.re. I also make post announcements on my Twitter.
