Kind of a tangent, but I was traveling in Portugal last year, and one day as I was headed to a train station I felt my phone buzz. I picked it up and it had a failed Bluetooth file transfer. In the settings, the device name had changed from the default to what looked like a base64 string, if I remember correctly. Unfortunately I didn't think to screenshot anything.

The phone was literally only a couple weeks old. Nothing new had been paired. I changed the name back and figured I would look it up later. The failed file transfer was automatically cleared (just a phone thing) and I wasn't able to find information about it.

A similar thing happened to my phone while I was at Defcon several years ago. After that I put my phone on airplane mode. Then when I got home, I reset all my passwords, and wiped the phone.

Is people trying to hack the attendees a common occurrence at Defcon?

I might be misremembering technologies, but I think in BT the incoming connection can directly execute commands on your device without any kind of identification/authorization.
