TenguCon returns for its third year! Organized by TenguSec, Tokyo's grassroots hacker collective, TenguCon brings together hackers, security researchers, industry veterans, and curious newcomers from around the world for two days of groundbreaking research, hands-on hacking, and genuine hacker culture.
This year's theme, "Human Resistance in the Age of Machine Authority," explores the collision of artificial intelligence, automation, cybersecurity, and human ingenuity.
Our headline keynote, "The Triforce," reunites legendary hackers Joe Grand (Kingpin), Iceman, and YTCracker on one stage!
The international speaker lineup also features Dave Lewis (gattaca), Oksana Verbytska, Anastasia Kovalchuk, Ricardo Fradique, Kameron Bettridge (Clovis Mint), BobDaHacker, BusesCanFly, VerticalSideways, Andrew Strutt (r0d3nt), and more.Expect original research and technical deep dives into offensive security, AI exploitation, space systems, cyber warfare, hardware hacking, industrial control systems, bug bounties, and everything in between. From hacking planetary rovers and smart bidets to satellite telemetry and real-world account takeovers, nothing is off limits to curiosity.
Interactive hacker villages, RF experimentation, and opportunities to connect with the international hacking community round out the experience.
TenguCon is built by hackers, for hackers.
No gatekeeping, no corporate theater. Just people sharing knowledge, breaking things, and building the future together.
Whether you're a seasoned operator or attending your first hacker conference, you're welcome here.ð https://tengucon.org
The future is not set.
