It is a 20 minute slot (and nothing more than a primer), but obviously, I want to capture their attention. I was thinking of working with the venue to set up a fake WiFi hotspot to capture those who randomly link to any hotspot, but how do I use that to full effect (e.g. anyone ever light up all their phones at once)? Or any suggestions about how to get their attention? Any topics that you think should be stressed? My plans for the talk will be about ransomware (and the need for backups), attacks on medical devices (hacking pacemakers, insulin pumps etc), (spear) phising attacks on providers/institutions, and awareness of social engineering — are there other topics that should be addressed?
