From Bangladesh 🇧🇩 · Currently in Malaysia 🇲🇾 · Learning by doing, documenting, and breaking things in labs
I'm Alif Abedin Siyam, a Computer Science student specializing in Cybersecurity at Asia Pacific University in Malaysia.
My current focus is offensive security. I am learning web security, bug bounty methodology, CTFs, HTB machines, Linux privilege escalation, and practical penetration testing.
I like turning what I learn into public work through writeups, labs, notes, dashboards, and GitHub repositories.
In CTFs, the categories I enjoy the most so far are OSINT, web exploitation, and privilege escalation.
- bug bounty methodology
- web exploitation
- CTF writeups
- HTB machines
- Linux privilege escalation
- penetration testing fundamentals
- practical homelab documentation
| Project | What It Shows |
|---|---|
| Cybersecurity Homelab | A private SOC-style lab using Wazuh, Suricata, DVWA, Juice Shop, Metasploitable, Docker, Tailscale, custom detections, and dashboards. |
| 30-Day CTF Writeup Challenge | A beginner-friendly CTF writeup series covering crypto, OSINT, forensics, privilege escalation, web exploitation, pwn, and reverse engineering. |
- KaffeeSec SomeINT TryHackMe OSINT Writeup
- Sakura TryHackMe OSINT Writeup
- RootMe TryHackMe Writeup
- SQLiLite picoCTF Web Exploitation Writeup
- FactCheck picoCTF Reverse Engineering Writeup
Short term: web security, bug bounty methodology, PortSwigger labs, CTFs, and retired HTB machines.
Long term: penetration testing, CPTS, OSCP, and stronger public offensive security work.
