TheProtector – Linux Bash script for the paranoid admin on a budget

In plain words

TheProtector is a Linux security monitoring tool built as a single Bash script for system administrators. It provides real-time monitoring of processes, networks, and files, includes YARA-based malware detection, eBPF kernel monitoring, and behavioral anomaly detection. The tool can actively respond to threats by blocking IPs, terminating processes, and quarantining files. It features a web dashboard and anti-evasion detection for rootkits. Designed as a lightweight alternative to expensive enterprise security software, it requires minimal setup and runs on modest hardware.

Linux Bash Script for the Paranoid Admin on a Budget - real-time monitoring and active threat response - IHATEGIVINGAUSERNAME/theProtector

In the maker’s words, at launch

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.…

  Deft-Intruder – Real-time malware detection daemon for LinuxNov 2025 · github.com · ▲6

  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 &#x2F;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&#x2F;proprietary.…

  Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better?

Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  Ten years of running every day, visualized▲958

  Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  Made this website as an exercise in vibe-coding and GCP.

  Use Their ID – Use your local UK MP’s ID for the Online Safety Act▲862

  Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
