Security researcher, reverse engineer extraordinaire. Finder of CVEs, hacker of Nintendo Switches/smart TVs, and staunch user freedom advocate. Many great writeups for non-beginners (or expert beginners), and even more great exploit PoCs on his Github.

Author of Wizard Zines, explainer of protocols & systems, and terminal witch. Julia has written hundreds of joy-inducing, mind-enhancing blog posts demystifying Linux internals, DNS, performance tools, debugging, etc. Pretty much any seemingly complex system that forms the backbone of general computing is fair game, and Julia does a great job of making those concepts simple and approachable. It's kind of their whole thing.

This is the reverse engineering introduction you've been looking for. Essentially the bible for first principles, program agnostic. Uses x86 intel assembly for examples. Currently a WIP, but there are writeups on both Windows PE and Linux ELF binaries for either flavor of reverse engineer.

Blog but also a hackerspace in Minneapolis with free and donation-based services including cloud storage, email, and a matrix homeserver.

Network security, sysadmin, and reverse engineering stuff. A mix of "how-to" guides, exploit writeups, and ramblings of a mad man. For an easy introduction, check out his article on Graph Theory. Then go and learn more graph theory.

A group of security researchers dedicated to worldwide free information sharing. They put a strong focus on individual liberty and privacy. Lots of their writeups are in Portuguese, so bonus points for the Brazilians out there.

Distributed systems engineer and researcher with a long track record of real-world impact. Helped build Delos at Meta (control-plane storage for nearly everything). His posts are a mix between system design and commentary on managing software teams.

Blog by Marc Ochsenmeier, author of pestudio. His articles are not so much articles as they are slideshows from various presentations on malware analysis and Windows internals. Check out some of the stuff on the "references" tab as well.

Sysadmin blog focused on BSD variants. The OpenBSD articles were especially helpful in getting my server configured to host this website.

Bug bounties and reinforcement learning. Not many articles, but a handful of really great ones.

Sander Dieleman's blog, a Google DeepMind researcher with a Computer Science Ph.D. focused on deep learning applications for music information retrieval. Writes about generative modelling, diffusion models, and the deep structure of latent spaces. His writeup "Generative modelling in latent space" is genuinely the best introductions to latent space in genAI models I've ever read.

Huge repository of bug hunting scripts and tools. So many amazing writeups, it's hard to pick just one. After you've done a CTF or two just read everything on this website and you'll be cracked.

Security researcher with a focus on fuzzing, static analysis, and heap exploitation. He recently found a Linux kernel zero-day in the KSMBD module using GPT-o3, and wrote a stellar post about it. Deep technical content, especially if you're into low-level bug hunting.

The ISP Column has been running since 2000, where Geoff Huston, Chief Scientist at APNIC, former IAB member, and early veteran of the internet dissects, criticizes, and philosophizes about the protocol specs and governance structures of critical internet architecture, including but not limited to: BGP, DNS(SEC), RPKI, QUIC, IPv6, IETF, OARC, and the wider architecture of the global network of networks.

Learn about the engineering challenges of cloud networking, routing protocols, network automation, and data center design without all the marketing fluff.

Published by vx-underground, Black Mass is the zine your antivirus warned you about. It's a reverent, occultish, satanic guide to all things malware. Things like AV evasion, unpacking 90's DOS viruses, UEFI bootkits, deciphering the ancient tomes of Windows internals, you get the gist. It's a fairly new zine as well. There are only two issues currently out, but when vx-underground has the time and the will, rest assured there will be more Black Mass.

A newcomer hacker zine that's focused on Linux exploits and the ELF file format. Think polymorphic shellcode, linker hijinks, reflective loaders, and anti-RE tricks that would make old-school vx-ers proud. We got scene interviews, Linux rootkits, and lots and lots of ELF binary hacking. If you want to get into Linux exploit dev and you can't read Chinese or Russian, this is one of the few English publications consistently pumping out new, high-quality Linux exploit techniques.

Legendary underground zine for hardware hackers, firmware freaks, retro tinkerers, and infosec archivists. Each issue is written by chaos goblins who want to teach you to write a bootloader that's also a byte-level palindrome and how to get past the latest mitigations and obfuscations attackers use when you're reverse engineering their pride and joy. It's serious exploit dev mixed with 1890's ads for American soap.

The world's first hacker zine. Part technical journal, part counter-cultural manifesto. They are about to release their 40th anniversary edition in Summer 2025. Phrack has been the underground's go-to for deep dives into exploit development, reverse engineering, phreaking lore, and hacker ethics. It's where classics like Smashing the Stack for Fun and Profit and Hacker's Manifesto were born. Each issue is a collection of technically profound exploits and commentary on the hacker ethos. Reading your first Phrack issue is a rite of passage for those who want to understand how systems break and why it matters.

A community-driven hacker zine where each article fits on a single page. Covers everything from demoscene and retrocomputing to modern exploits, compiler wizardry, and weird hardware. Lots of cool art as well. Founded by Gynvael Coldwind and built on the labor of many other talented people.

Gay isopods unite for user freedom, privacy, and other cool shit on the internet.
