Zion Leonahenahe


Hacker turned Security Researcher


About Me

I’m a a Ph.D. student at Arizona State University studying Computer Science with a focus in Systems Security. You may know me online as mahaloz. I was born and raised on the Big Island, and I’m proudly Native Hawaiian. When I’m not doing research I like to play in ethical hacking competitions called CTFs with the internationally known team Shellphish as one of the co-captains. I also run the ASU Hacking Club, which is the pipeline to Shellphish.

I research with the computer security lab SEFCOM at ASU under Dr. Fish Wang and Dr. Yan Shoshitaishvili. I’m interested in most things binary analysis, but I especially like: decompilation, the reverse engineering process, and CFG recovery. I also like working on educational outreach material, like the education platform pwn.college, as well as open-source security tools which can be found on my GitHub.
