Chris Hadnagy vs. DEF CON Lawsuit update 2025/02/24 It’s been a while since our last update - a lot has been going on behind the scenes - and with the discovery phase complete we have filed a motion for summary judgement asking the court to dismiss his lawsuit. In it we reveal some of the identities of those who testified regarding their experiences with Chris, and I would like to personally thank them for standing up for our community when remaining silent would have been easier. The legal standard for evaluating a summary judgement motion means giving the benefit of the doubt to the nonmoving party (Hadnagy) on all disputed facts. Because of this we focused on the undisputed facts, including the documents and deposition testimony, that Chris can’t deny. Should this motion fail then we would start preparing for trial, and end up arguing over the disputed facts as well. Both sides will be done with briefing in approximately one month. After briefing is complete we expect the judge to rule on the motion within a couple weeks to a couple months. Thank you everyone for continuing to support DEF CON, and a special thank you to all those who came forward in the ongoing lawsuit. Jeff Moss, President, DEF CON Communications.
