Summary
Tengu Underground 10.0 is a monthly hands-on cybersecurity workshop hosted by TenguSec, building on the format established after TenguCon 2.0. The session runs for seven-plus hours and includes lunch, with an optional group dinner afterward.
There are no scheduled speakers. Attendees work through ethical hacking exercises covering web application security, network security, and white hat techniques in a beginner-friendly environment, learning by doing and sharing knowledge with peers. It is positioned as a follow-on for people who have come through prior TenguSec gatherings like 2600 Meeting or TenguCon.
The venue is in Ginza, Chuo City, but the exact address is shared with registered attendees only ahead of the event. Guests must also register in advance.
About the community
