Defcon is not the place I’d want to wear something like that and make myself a target. Of course, I’d be embarrassed to wear them anywhere, but afraid at Defcon.
Shit, I’d be scared to go anywhere near defcon with any device.
I'd go in with an abacus and a notepad.
“Hey, where’d all my beads go?!”
Suddenly your abacus explodes after 65,535 beads suddenly appear.
Eh, it's not that bad
Random files appearing in the downloads folder on my phone has only happened once
¯\(ツ)/¯
Let me guess, it was an iPhone? Someone just used AirDrop and you might've allowed everyone sending you files.
It was Android :-) WiFi, NFC and BT turned off. It was Android 12 I believe, back in 2022.
Did you use a "supplied" charger while there?
Nope - aware of juice jackers, so I only used my own cables and adapters (even have a USB condom).
I'm generally pretty security aware, but my only theory of how it landed there is some cellular exploit. Whether it was a crafted MMS, a custom cell site, or something else I don't know.
I did use mobile data for some ubers, but that was off-site.
That's actually a bit frightening and the feeling of being violated would linger for a while.
My goodness, your username!?!
I think you might already know...
