Hi HN, I built a small Linux CLI tool called witr (Why Is This Running?). The idea came from a situation most of us have hit: you log into a machine, see a process or port running, and immediately wonder why it exists, who started it, and what is keeping it alive right now. witr traces a process, service, or port back to its origin and responsibility chain and explains it in a way that’s quick to read, especially when you’re debugging under pressure. This is v0.1.0. It’s intentionally small and focused. Feedback, criticism, and edge cases are very welcome. Repo:…

I noticed the growing security concerns around MCP (https://news.ycombinator.com/item?id=43600192) and built an open source tool that can detect several patterns of tool poisoning attacks, exfiltration channels and cross-origin manipulations. MCP-Shield scans your installed servers (Cursor, Claude Desktop, etc.) and shows what each tool is trying to do at the instruction level, beyond just the API surface. It catches hidden instructions that try to read sensitive files, shadow other tools' behavior, or exfiltrate data. Example of what it detects: - Hidden instructions…

Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN. I live in the CLI, but when it came to discovery and monitoring, I found it limiting. So I built a GUI that brings my favorite tools together in one place. PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted more: fast, reliable scans using ARP tables and ICMP. As a Wi-Fi engineer, I couldn’t stop there. I kept adding ways to…

Hey there HN! ruroco (RUn RemOte COmmand) is a tool that lets you execute commands on a server by sending UDP packets (instead of knocking on ports). the tool consist of 3 binaries: - client -> runs on your notebook/computer and sends the UDP packets - server -> receives the UDP packets and makes sure that they are valid - commander -> runs the command encoded by the data of the UDP packet if it's valid The commands are configured on the server side, so the client does not define what is going to be executed, it only picks from existing commands. I use this tool to open up the SSH port…

I found it odd there wasn’t a simple web tool to scan Docker Hub images for vulnerabilities. So I built one. It’s powered by the popular open-source tool Trivy.

Hi HN, Recently I wasted several hours wrangling my dev environment only to find out that the browser frontend was talking to the wrong version of the backend. This got me thinking--why on earth are we still using simple numbers to describe which process to connect to? Why not use names instead? I thought of all the times a program wouldn't start because of port conflicts. The more I thought about it, the crazier it seemed. Modern operating systems already offer no-conflict ports: if you make your TCP server listen on port 0, the OS assigns you a random available port. But that only solves…

TL;DR explanation (go to https://github.com/Sakura-sx/Aroma?tab=readme-ov-file#tldr-e... if you want the formatted version) This is done by measuring the minimum TCP RTT (client.socket.tcpi_min_rtt) seen and the smoothed TCP RTT (client.socket.tcpi_rtt). I am getting this data by using Fastly Custom VCL, they get this data from the Linux kernel (struct tcp_info -> tcpi_min_rtt and tcpi_rtt). I am using Fastly for the Demo since they have PoPs all around the world and they expose TCP socket data to me. The score is calculated by doing tcpi_min_rtt/tcpi_rtt. It's…
