The security community is full of interesting characters who have had meandering, random paths to success, and Adam O'Donnell fits that description quite nicely. A gifted student who studied engineering and went on to earn a Ph.D. in computer science, O'Donnell has been a staff engineer, a startup founder, a political fundraiser, and a member of the famous Cult of the Dead Cow hacking group for nearly 20 years. He joins Dennis Fisher to talk about his introduction to the hacking scene in the '90s, joining the cDc, Beto O'Rourke's influence on the group, and the new book about the cDc.
