Looking to get some feedback from the Hacker News community. I wrote the book with a focus on penetration testers and red teamers, but there are great examples for network admins, developers, and blue team defenders as well. You can pick up a copy for free here through May 19, 2019: https://gumroad.com/l/the_cyber_plumbers_handbook/hackernews... Please note, because it's hosted on Gumroad, it does require an email. If you don't want to give out your actual email, check out an anonymous email service. I give it away to students for free, so if you know of one that…

I wrote this intermediate-level book as a showcase of various FOSS, mostly command line tools. I'm a nuclear engineer and found myself teaching other nuclear, mechanical, and electrical engineers these tools again and again, so I wanted to package them into book form. I attempted to make it even broader interest, so it's not just about engineering. In the end, it's a fairly eclectic set of topics. Anyway, after selling for a few years, I just decided to release a slightly updated version of it in full for free. You'll find full HTML, PDF and ePub versions (all built with Sphinx) at the link.

There is too much of everything in cybersecurity. Noise, FUD, unfulfilled sales promises, incidents, things to address, information to process, technologies to look at, people to educate. I am working as a CISO and it's mostly my job to raise awareness, understand all the risks, track all current issues and prioritize them, and be able to communicate all that with proper references and examples to our management team. I've been building and dogfooding a tool that ingests much of the noise and provides focused notifications per cybersecurity topic and regular awareness texts. The idea was to…

Hey HN, I’ve been working on Phended, a cybersecurity education site focused on making defensive knowledge approachable—especially for small businesses and non-technical users who don’t have time to dig through jargon-filled resources. Right now, it’s a mix of free tools, guides, and checklists, with a chatbot assistant named Dave who helps answer questions. I’m gearing up for a full refresh as I build out more content and structure things better, so it’s still early days—but I’d love to get feedback before I go too deep into the overhaul. Some stuff I’m planning - More actionable guides and…
