The "Crypto and Privacy" village at Defcon demands you agree to the privacy policies of Salesforce, Google, Microsoft, and Discord to interact with them. It is a disgrace. Defcon stopped caring about privacy, hacker ethos, and digital sovereignty a long time ago. Go there if you want to talk to their military recruiters or buy/sell proprietary snake oil security SaaS. It is really just another corpocon at this point.…

Defcon was always the most government-aligned conference. Historically, BlackHat was Defcon's slightly more counter-culture counterpart/foil. These days, I don't think anti-establishment hackers have any physical conference gathering.

Earlier quoted context omitted.

They have a sign similar to the ones at stadiums or events that say recording is in progress and that by being there you agree to be recorded... being here means you agree... not that there is any enforcement but very flocky and thus ironic.

That's not Google though?

MoneroKon and Monerotopia.

Is anyone familiar with the laws surrounding police basically operating their own pseudo cell towers?

I would assume this would be highly illegal for individuals, what sort of hoops did law enforcement need to jump through to get this type of approval? Did FCC need to rubber stamp this?

Wouldn't you be essentially doxxing yourself by attending?

Glad this one is getting the "second chance" bump back to the front page. It's great content and it's timely. It's a great video. If you're not inclined to watch the video I'll save you a click to the youtube description and add a bit more detail than the earlier sibling for the devices shown: Simulacra "Simulacra continuously fabricates a churning crowd of plausible-but-fake wireless devices around you — drowning yo…

>"Simulacra continuously fabricates a churning crowd of plausible-but-fake wireless devices around you — drowning your real devices in noise so that passive trackers, ALPR add-ons, and co-travel correlators can't reliably pick your signal out of the crowd — while passively watching for the trackers that follow you." "Oh, it's that guy with the bluetooth spammer." https://xkcd.com/1105/

If they became cheap enough, you could deploy them "permanently" to leave around town. Hang 'em on the same pole the Flock cameras are mounted, or on the ground in one of those hide-a-key things shaped like a rock on the ground near the pole. Just toss one out as you drive by type of situations. It's all solid state, so should be okay being tossed around a bit.

In general, interfering with a radio link can be hundreds of thousands of dollar fines, and years in prison.

Almost every RF (legal) communication device consumers own will back off broadcasting if it detects collision or interference.

The fact many governments of the past few decades feel entitled to run intelligence campaigns on their own citizens often points to a degenerative despotic trend.

The best plans simply don't require secrecy, and everyone has fun. =3

Partial summary: -ESP32 based device that tries to detect bluetooth/MAC addresses of flock cameras and beeps when it does - a Stingray detector that runs on a second-hand mobile hotspot - a device that alerts you about things that are moving approximately with you (AirTags, SSIDs, etc).

Sigh, researchers used to publish cutting edge stuff.

That list reads like a fist year lab schedule. lol =3

John Oliver did a piece on this a couple of weeks ago. The videos are not widely available outside of the US, but here's a Guardian write-up [0], and in the UK you can get access to the episode via catch-up if you have Sky Atlantic.

TLDR: the police do this whenever they want, pretty much.
