I Built a Network Security Scanner From Scratch in Python | VeilScan v2.0

Описание: Nmap gives you port numbers. No explanations, no context. A beginner scans a machine, sees an open port, and has no idea if it matters.

So I built VeilScan — a multi-threaded network security audit tool that scans, identifies, and explains every open port in plain English.

In this video:
→ Live scan of Metasploitable — 19 open ports found in 50.82 seconds
→ 8 CRITICAL findings, explained in a full HTML report
→ How the TCP thread-pool engine works, and the race condition bug I had to fix
→ Why my OS detection showed Windows for every Linux machine, and the actual fix
→ HTTPS banner grabbing with Python's ssl module
→ Full architecture: 29 files, 368 tests, zero mandatory dependencies

Real findings from the scan:
→ MySQL 5.0.51a — a 2008-era database exposed directly on the network
→ vsFTPd 2.3.4 — the version with the well-known hardcoded backdoor
→ rexec, rlogin, rsh (ports 512–514) — unencrypted 1980s Unix remote services
→ SMB (port 445) — the same port EternalBlue used to spread WannaCry to 300,000+ machines in 2017

This is a real tool I use in my own home lab, not a tutorial-only project.

Pure Python. Zero mandatory dependencies. MIT licensed. Open source.
