Decentralization isn’t just a trendy buzzword. When platforms enclose the web—locking culture, knowledge, and communities into corporate silos—they decide what survives, what gets erased, and who has access. A decentralized web is survival against erasure. #decentralization #mastodon #Foss #openweb

Every year we try to bring something new to the table—literally. This year it’s five DEF CON editions, 20 author sigings, Rudy in shirt form, and a huge lineup of titles you’ll actually want to read. Come flip through the weird, the sharp, and everything we couldn’t wait to share. Always an honor to build for this community--thanks for keeping it brilliantly strange. See you next week @DEF CON #DEFCON32 #infosec #redteam #cybersecurity #hackers #programming #books #bookstodon

Final DEF CON edition drop! What’s really sold in dark web markets? Reversing the Dark Web explores the underground cybercrime economy through real ads and real malware samples. This book walks you through stealers, loaders, ransomware, crypters, and more—with hands-on reverse engineering using Ghidra and x64dbg. Look for the @Ś edition at our booth this year! Also available for pre-order:

Dissecting the Dark Web

A technical exploration of the malicious software bought and sold on the dark web, where bad actors offer malware-as-a-service (MaaS) to the highes...

Red Teaming AI is coming to @DEF CON , but not in any form you’ll find online. We’re bringing a special edition to the booth, and once they’re gone, they’re gone. Phil will be there to sign copies while supplies last. If this is your kind of thing, you’ll know where to find us! #Defcon #RedTeam #CyberSecurity #InfoSec #ThreatIntel

Building your own debugger is a powerful way to understand Linux internals. From forking and tracing to handling signals and interacting with registers, you'll gain practical insight into how debuggers actually work. It’s also a solid exercise in writing clean, testable C++ systems code.

Building a Debugger

Master the inner workings of your x64 Linux system and expand your OS expertise by writing your very own debugger using C++.

Gatekeeping in tech is like hoarding knowledge during a zombie apocalypse: unhelpful, isolating, and honestly just weird. In a field that thrives on collaboration and shared solutions, keeping others in the dark doesn’t make you look smarter—it just slows everyone down. Teach. Document. Help. It’s how we all survive the chaos. #tech #community #sharing #knowledge
