DEF CON organizers banned social engineering expert Chris Hadnagy for multiple violations of its policies.
1. We received multiple CoC violation reports about a DEF CON Village leader, Chris Hadnagy of the SE Village. After conversations with the reporting parties and Chris, we are confident the severity of the transgressions merits a ban from DEF CON.
2. We have also taken the rare action to disband the DEF CON Group DCG414. Code of Conduct violations by the group’s primary Point of Contact and subsequent mishandling of the event left us without confidence in the group’s leadership.
After his ban, Hadnagy took to Twitter to say he did not know what led to his ban.
