Hey infosec folks 👋

I built RYN27 — a free, open-source CLI recon tool written in Python.
MIT licensed — fork it, contribute, do whatever you want with it.

I’d love feedback from people who actually do this work.

What it does:

🔍 WHOIS · Full DNS enumeration · Subdomain brute-force
🔒 SSL/TLS cert inspection with expiry countdown
⚡ Threaded port scan + banner grabbing (30 workers)
📊 HTTP security header audit with 0–100% scoring
🌍 IP geolocation + proxy/VPN detection
✉️ Email & contact harvester
🛠️ Tech stack fingerprinting
📄 robots.txt reader, metadata crawler, zone transfer

19 modules. One interactive menu. Zero config.

Runs on:
Linux · macOS · Windows · Termux ✓

All dependencies auto-install on first run.

If you try it — I genuinely want to know:

→ What’s missing?
→ What’s broken?
→ What would you do differently?

Open to all feedback, suggestions, PRs, criticism — all of it. 🙏

@Ruyynn sounds cool.

I just need to find a way to bundle it with like a python runtime as statically linked binary if I want to get it to work on #OS1337.

@kkarhan
Thanks! Glad you like it.

Yeah, bundling it into a standalone binary is something I've been thinking about (maybe PyInstaller / Nuitka).

If you manage to get it running on OS1337 I'd love to hear how it goes.

@Ruyynn right now it can't run on _OS/1337 because the network stack is missing.

Cuz #RYN27 looks promising and useful and when it comes to a #CLI / #TUI-based distro, that seems to be a powerful tool to have on hand...

Thanks for checking it out and adding it to the wishlist, I really appreciate that.

A standalone binary build (PyInstaller / Nuitka) is something I'm planning to experiment with soon.

Once that works reliably I'll definitely share it — it would be great to see RYN27 running on OS/1337

@Ruyynn thx.

Feel free to ping me once there's like a all-in-one binary to plop down, I'll give it a spin.

  • If it works on #mkroot (which is basically the upstream of #OS1337) I'm confident it'll work on _OS/1337...

Awesome, thanks Kev!

I’ll work on creating an all-in-one binary (using PyInstaller or Nuitka) and ping you as soon as it’s ready to test on #mkroot.

Really appreciate your willingness to give it a spin!

@Ruyynn granted, I myself can see the value of #RYN27 as a tool and would've loved to have it in the past already…
