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.
“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...
I was afraid walking into the room with the wall of sheeple just bc I was wearing a button down in spite of being the sole sponsor of the hackathon. I (as instructed) left my watch, phone, laptop etc at hotel and only brought locked down Chromebook and lived in sweaty terror every keystroke. All while they were stoked and loving the sponsor not just buying a logo, and sent me back with like 500 bucks in swag easily to share back home at the office. Still.... Terror.
Fortunately most of the attendees are genuinely good folks, so generally what really happens is just that some data gets scraped and everybody has a bit of a laugh at one of the talks.
I know worse happens, I just think it’s worth mentioning it is actually a group of mostly awesome people.
Such as? I don't think I'll ever attend this kind of event due to geographic and financial constraint.
And I can imagine just bringin my EOL android 12 and using it as is even only cellular is a pretty reckless, but if I just bring clean phone for emergency purpose it should be fine right?
I’m not saying that wrt phones only. But credit cards get skimmed and various other atm pranks. Loads of infrastructure takedowns. Zero days released into the wild with viruses attached. All sorts of shenanigans.
