THOTCON is a hacking conference based in Chicago, Illinois, known for its underground and community-driven approach to cybersecurity. The name comes from Chicago’s original telephone area code, 312 (THree-One-Two). This is a non-profit, non-commercial event looking to provide the best conference possible on a limited budget.

It’s a nonprofit event that provides a mix of technical talks, workshops, and villages covering various cybersecurity topics. The conference is held at a top-secret location, only disclosed to attendees shortly before the event.

The next THOTCON, THOTCON 0xD, is scheduled for May 30-31, 2025. It features multiple speaker tracks, contests, and hands-on hacking challenges, including lockpicking, wireless security, and more. There’s also an after-party with live music and hacker culture entertainment.
