Hello there, I’m Fahmi, or ef for short. I’m an IT security enthusiast from Indonesia who aspires to be a pentester.

In random time, I will be publishing IT related stuff, CTF solutions, or something else that tickles my interests.

Unless otherwise stated, all published posts are entirely my personal opinion/view. If you discover something incorrect with my blog, please let me know, so I can rectify it immediately.
