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…

Time to announce Noisy Sockets Shell, the first in a series of WireGuard powered applications I'm working on. Noisy Sockets Shell is an SSH replacement that uses WireGuard for authentication and encryption, and WebSockets for communication. CLI and browser client available.

Your AI agent hits an infinite loop and racks up $2000 in API charges overnight. This happens weekly to AI developers. AgentGuard monitors API calls in real-time and automatically kills your process when it hits your budget limit. How it works: Add 2 lines to any AI project: const agentGuard = require('agent-guard'); await agentGuard.init({ limit: 50 }); // $50 budget // Your existing code runs unchanged const response = await openai.chat.completions.create({...}); // AgentGuard tracks costs automatically When your code hits $50 in API costs, AgentGuard stops…

This is a small PoC Python project for web server access logs analyzing to classify and dynamically block bad bots, such as L7 (application-level) DDoS bots, web scrappers and so on. We'll be happy to gather initial feedback on usability and features, especialy from people having good or bad experience wit bots. *Requirements* The analyzer relies on 3 Tempesta FW specific features which you still can get with other HTTP servers or accelerators: 1. JA5 client fingerprinting (https://tempesta-tech.com/knowledge-base/Traffic-Filtering-b...). This is a HTTP and TLS layers…

Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

There is a growing number of companies offering anti-bot protection SaaS to protect websites from scraping by automated bots based on Puppeteer/Selenium. Most of them rely on browser properties such as headers, javascript properties (window., navigator.), behavior analysis, to build device/user fingerprints and match it against a database of "whitelisted" fingerprints (typical user behavior/settings/device props etc). For the past few months, together with two other devs I have worked on a customized Puppeteer/Playwright scraping backend. It's essentially a drop-in…

I kept seeing every npm/pnpm/yarn/bun/uv supply chain post end with the same advice (set a minimum release age, turn off install scripts), and while I know cooldowns are "controversial", they do work. But even if you convince people that they should set cooldowns, it seems many don't end up following through, not sure why, maybe because it means hand-editing five config files in five formats with five different time units, or perhaps the "it won't happen to me" syndrome (or "I'll do it later, it seems complicated" where it's actually very simple). So I created a tool that…

Hey HN I built a tool called ClipCapsule, a clipboard manager for Linux that's designed to be entirely keyboard-driven. Here’s what it does: Lets you recall and paste previous clipboard entries using just CTRL + SHIFT + 1~9. Keeps a history of everything you copy, in a local database. Moves selected items to the top of the clipboard stack (so CTRL + V pastes it). Built with Go + WailsJS for a fast native feel. No cloud. No telemetry. No fluff. Right now, you’ll need to run it with sudo or allow access to /dev/input/eventX for keyboard capture. We’re working on a proper daemon…

Hi! I've been working on a child monitoring service and I'd really appreciate your input on it. The structure of the service is pretty technically interesting. It sets up a wireguard VPN on the child's Windows account, and then routes the traffic to our server. From there, we use mitmproxy to break open the TLS, inspect the packets, and then re-encrypt them. Currently all images are passed through an ImageNetV2 model, and for sites like reddit or google, individual links/communities are analyzed and we remove the content if it violates the filters without impacting the overall browsing…

I built an open-source malware detection daemon that monitors all running processes in real-time using ML + heuristics. No kernel modules or eBPF required. Key points: - Polls /proc for new processes (works on any Linux kernel 2.6+) - Random Forest model trained on EMBER 2018 dataset (2.3M samples) - Heuristic rules for crypto miners, ransomware, rootkits - ~20MB RAM, <1% CPU, sub-millisecond scan latency - Pure C, zero runtime dependencies - Model embedded directly in binary (50KB) Why I built this: Existing solutions either require modern kernels (eBPF) or are heavy/proprietary.…
