About h@cktivitycon

h@cktivitycon is a HackerOne hosted hacker conference built by the community for the community. After a successful inaugural h@cktivitycon 2020 with over 12,000 registrants, we are back this year for an even bigger and better conference!

h@cktivitycon is a place for hackers to learn, share, and meet friends. Join Vickie Li, STÖK, NahamSec, and friends for CTFs, prizes, talks, villages, and more for h@cktivitycon 2021.


Do you have a security story to tell? How about lessons learned from the front lines, exciting new tools or a fresh take on bug hunting? Why not present it to thousands of hackers around the globe? Share knowledge, educate peers, and together, we will hit harder. The CFP closes August 12th and speakers will be notified by August 18th. Check out our CFP page for more info.


Starting new this year, we are introducing villages to h@cktivitycon. Stay tuned for more information.
