Abdulmohsen Alwaleed

[bio]

I don't just test systems — I break them down to understand how they think.

I build low-level Python frameworks that automate reconnaissance, fingerprint networks, and simulate real attacker behavior in controlled environments. My work is driven by curiosity, not routine — every target is a system waiting to be understood.

Outside of code, I operate in the physical layer of security: reverse-engineering IoT devices, experimenting with ESP32/Arduino systems, and exploring NFC behaviors beyond standard usage — from tag manipulation to hardware-based attack simulations.

// I exist in the gap between software and hardware, where real-world attack surfaces actually live.

Lifelong Learner — constantly evolving, breaking limits, and refining my understanding of offensive security.

[experience]

Network Reconnaissance & Automation

Constructed multi-threaded TCP port scanners, automated banner grabbing service fingerprinting utilities, and mapped active web endpoints dynamically.

Hardware & IoT Security

Deployed specialized hardware lab targets using ESP32, Arduino, and PN532 modules to extract UID sequences and execute live RFID/NFC tag emulation checks.

Vulnerability Assessments

Conducted internal audits, documented penetration testing findings, and participated in Capture The Flag challenges to identify attack vectors and entry points. Completed hands-on exploitation labs on TryHackMe, along with structured practice on Hack The Box Academy. Actively engaged in offensive security labs and scenarios on Hackviser and PortSwigger Web Security Academy to strengthen real-world penetration testing capabilities.
