picosnitch helps you protect your security and privacy by "snitching" on anything that connects to the internet, letting you know when, how much data was transferred, and to where. It uses BPF to monitor network traffic per application, and per parent to cover those that just call others. It also hashes every executable, and will complain if some mischievous program is giving it trouble.

Hi HN, I spent the past year building this in my spare time because I got tired of enterprise security tools that cost $50K/year and don't understand Linux. TheProtector is a comprehensive security monitoring tool that actually runs on the systems we use (Linux) instead of being a Windows-first afterthought. Built it entirely on a $500 laptop because I believe good security shouldn't require unlimited budgets. Features: - Real-time process, network, and file monitoring - YARA malware detection with custom rules - eBPF kernel monitoring (when available) - Behavioral baseline…

Pico is an open-source alternative to Ngrok. Unlike most other open-source tunnelling solutions, Pico is designed to serve production traffic and be simple to host (particularly on Kubernetes). Upstream services connect to Pico and register endpoints. Pico will then route requests for an endpoint to a registered upstream service via its outbound-only connection. This means you can expose your services without opening a public port. Pico runs as a cluster of nodes in order to be fault tolerant, scale horizontally and support zero downtime deployments. It is also easy to host, such as a…

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…

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…

hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

Hi HN, I've built an app for macOS that allows performing common SSH operations on Linux servers using a native GUI. The problem: Managing multiple Linux servers usually means juggling terminal windows and copy-pasting snippets/scripts. After dealing with tens of production/staging VPSes at previous jobs, I realized there had to be a better way for common operations I did on a daily basis than my collection of bash snippets. Features: - Quickly switch between different servers. Tag servers with arbitrary key values for easy search. - Real-time dashboard with CPU/memory graphs,…
