What it is, how to fix and detect it, and how to reproduce the full pre-auth RCE in a hands-on lab. https://uphack.io/blog/post/fundamental-security-principles/ https://uphack.io/blog/post/fundamental-security-principles/ Sun, 15 Mar 2026 00:00:00 GMT This post is all about the “big ideas” behind secure systems, like least privilege and separation of duties. These principles are surprisingly simple but form the backbone of how we design systems to stay safe from attacks. https://uphack.io/blog/post/you-are-the-bottleneck-now/ https://uphack.io/blog/post/you-are-the-bottleneck-now/ Sat, 14 Mar 2026 00:00:00 GMT AI can now generate code, fixes, and explanations faster than most developers can properly evaluate them. That sounds like a productivity breakthrough. It may also be the fastest way to become a worse engineer without noticing. https://uphack.io/blog/post/the-illusion-of-building/ https://uphack.io/blog/post/the-illusion-of-building/ Sun, 01 Mar 2026 00:00:00 GMT AI makes it dramatically cheaper to produce software that appears to work. But 'building an app' and 'engineering a system' are two different activities that people keep confusing, and the gap between them is where most of the actual work lives. https://uphack.io/blog/post/security-is-not-a-code-problem/ https://uphack.io/blog/post/security-is-not-a-code-problem/ Sun, 22 Feb 2026 00:00:00 GMT Security is having a moment: new tools can read code, find bugs, and even suggest fixes. Some people took that to mean cybersecurity is basically over. This is my take from the inside: what’s actually changing, what isn’t, and why security was never just a code problem. https://uphack.io/blog/post/access-control-authentication-and-authorization/ https://uphack.io/blog/post/access-control-authentication-and-authorization/ Sat, 21 Feb 2026 00:00:00 GMT How do systems make sure the right people get in, and the wrong ones stay out? In this post, we’ll dig into authentication (proving who you are) and authorization (what you’re allowed to do). They’re simple ideas, but they have a massive impact on security. https://uphack.io/blog/post/foundations-of-information-security-cia-triad/ https://uphack.io/blog/post/foundations-of-information-security-cia-triad/ Sun, 15 Feb 2026 00:00:00 GMT The CIA triad isn’t just a catchy acronym. It’s the backbone of security. We’ll break down confidentiality, integrity, and availability, and see how they shape the way we think about protecting systems and data.  https://uphack.io/blog/post/introduction-to-information-security/ https://uphack.io/blog/post/introduction-to-information-security/ Sat, 14 Feb 2026 00:00:00 GMT We cannot start a meaningful exploration of computer security without defining the subject itself. In this post, we'll talk about what security actually means. https://uphack.io/blog/post/how-to-start-your-offensive-security-career/ https://uphack.io/blog/post/how-to-start-your-offensive-security-career/ Sun, 09 Mar 2025 00:00:00 GMT Is hacking like in the movies? How do I start? What do I need to know? What skills should I have? These are...
