Hey, I'm Sourabh 👋

Cybersecurity enthusiast recently living in Delhi, India  |  Self-taught security toolbuilder  | 

🧠 About me

I started with basic Linux commands on Termux and got curious about how systems get attacked and defended. In June 2026 I built 5 cybersecurity tools from scratch in one week — using Python, self-study, and a lot of trial and error.

Every line of code in my repos is understood, not just copied.

🛠️ Projects

Project What it does Concepts
Web Vulnerability Scanner Detects XSS, SQLi, missing security headers OWASP Top 10, HTTP, BeautifulSoup
Network Port Scanner Multi-threaded TCP scan + banner grabbing Sockets, threading, recon
Cryptography Toolkit Ciphers, hashing, password strength analysis SHA256, Caesar, Vigenère, Base64
Log Analyzer & IDS Detects brute force, scanning, malicious IPs SIEM, blue team, regex
Phishing URL Detector Heuristic scoring across 8 phishing checks Brand spoofing, TLD analysis, OSINT

📅 How this portfolio was built

June 15 → Set up environment — Web Vulnerability Scanner

June 16 → Network Port Scanner

June 17 → Cryptography Toolkit + Log Analyzer IDS

June 18 → Phishing URL Detector

June 18 → GitHub profile — you are here **Started from zero projects. Built 5 working security tools in less than 5 days. Not because I had to. Because that's what interests me and thats what i want to do.

🎯 Goal

Get selected for IIT Kanpur B.Cyber 2026 and work on problems that matter for India's digital security.

"Future conflicts will be fought as much in cyberspace as in the physical world." — Prof. Manindra Agrawal, Director IIT Kanpur
