In what has become an annual and much-anticipated event at Exfil, our team again went on its yearly pilgrimage to the DEF CON security conference in Las Vegas. As always it was a non-stop whirlwind running around trying to catch presentations, meet up with potential clients, do some team building, and grab delicious food. Now that we are back at work, I thought it might be fun to share some personal observations from DEF CON 2023.
