Hey infosec folks ๐
I built RYN27 โ a free, open-source CLI recon tool written in Python.
MIT licensed โ fork it, contribute, do whatever you want with it.
Iโd love feedback from people who actually do this work.
What it does:
๐ WHOIS ยท Full DNS enumeration ยท Subdomain brute-force
๐ SSL/TLS cert inspection with expiry countdown
โก Threaded port scan + banner grabbing (30 workers)
๐ HTTP security header audit with 0โ100% scoring
๐ IP geolocation + proxy/VPN detection
โ๏ธ Email & contact harvester
๐ ๏ธ Tech stack fingerprinting
๐ robots.txt reader, metadata crawler, zone transfer
19 modules. One interactive menu. Zero config.
Runs on:
Linux ยท macOS ยท Windows ยท Termux โ
All dependencies auto-install on first run.
If you try it โ I genuinely want to know:
โ Whatโs missing?
โ Whatโs broken?
โ What would you do differently?
Open to all feedback, suggestions, PRs, criticism โ all of it. ๐
