    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…

    We at Emerge Tools (YC W21) recently released open source Hacker News apps for both iOS and Android. The apps use the latest SwiftUI and Compose frameworks and are entirely native. Our goal is to help dogfood our products, but more importantly our team just enjoys reading HN every day and wanted an app to hack on and call our own. :) We are still missing some features but should otherwise be pretty solid. And open to any contributions. iOS: https://apps.apple.com/us/app/hacker-news-by-emerge/id674092... Android:…

    Hey HN, it's Farrukh and Umar. We're building listen.dev–a tool for proactive security monitoring in GitHub Actions to secure software releases from supply chain threats. Why we built this: As friends and collaborators for over a decade, we've been working on various startup ideas in dev tools and infrastructure. In 2017, while building an ML ops toolkit on Kubernetes, we got hacked. During a pilot with a fintech customer, our cluster became victim to a crypto-jacking attack. As it turned out, a dependency in our container base image contained malware (a Monero miner) which triggered inside…

    I made a Hacker News reader for iOS with React Native and Redux. It was mostly for me to learn more about React Native, but I'm really happy with the result. Let me know what you think! I'm hoping to add a lot more features, the first being a settings page with some color settings and dark mode. App: https://appsto.re/us/czg7hb.i Code: https://github.com/seanyesmunt/hackernews

    Hey HN, A long time ago, due to the lack of viable solutions with E2EE and offline-first syncing, I decided to dedicate my time to making one (which has its own story: https://yaad.one/blog/yaad-story). In the course of ~3 years, I developed a knowledge management app with these primary features: - Primitives: Notes, Tasks, Contacts - Grouping with "Boxes" - Offline-first - Multiplatform; currently available for Android, Windows (x64), macOS, and Linux (ARM). - Fully end-to-end encrypted (AES-256-GCM) - 13 Languages, 8 calendar systems - Light & dark mode Last night, I…

    Hello Hacker News! We’re Willem, Roeland, Felix and Madeline from Aikido Security (https://aikido.dev/) We’re building a “no BS’ application security platform. It’s the platform we wish existed, but couldn’t find. Willem, our CTO had to manage (application) security at many of his previous startups, and honestly, hated it. Most security tools we had to use made us feel dumb. They were super complex and riddled with false positives. Their platform was behind the book a demo button. They had intransparent pricing models and honestly charged us way too much. We think most of…
