Cybersecurity student at USTHB, Algiers — focused on cryptography, malware analysis, and breaking things in CTFs to learn how to defend them.
0x01 — About
I'm a cybersecurity student at USTHB (University of Science and Technology Houari Boumediene), working through cryptography, malware analysis, and capture-the-flag challenges one write-up at a time.
Most of what I know comes from taking things apart: implementing classical ciphers from scratch, running malware samples in an isolated lab to watch how they behave, and chasing flags in CTFs to build the muscle memory that theory alone doesn't give you.
I document what I learn on GitHub and share progress on YouTube — open-source tools, lab notes, and write-ups as I go.
