Whoever designs their logos definitely needs a raise IMO.

I'd buy all the stickers if it didn't cost twice their value just to ship them to me.

[–] AnarchistArtificer@slrpnk.net 10 points 1 week ago

I hadn't noticed this until you pointed it out, but yeah, their logos are fire

Do these work with European bands? Is it worth shipping to Europe?

[–] db2@lemmy.world 7 points 1 week ago

It probably doesn't matter which specific band.

[–] Andromxda@lemmy.dbzer0.com 2 points 1 week ago

I honestly don't know

[–] Ulrich@feddit.org 10 points 1 week ago (2 children)

I did not understand any of that...

[–] Andromxda@lemmy.dbzer0.com 59 points 1 week ago (1 children)

This is the easiest explanation I could come up with:

Your phone (or other cellular devices) constantly broadcasts a few identifiers. The IMEI, which is tied directly to the cellular hardware in your device, and the IMSI, which is tied to your SIM card. Law enforcement uses so called cell-site simulators, which basically pretend to be cellular antennas, while actually just grabbing IMEIs and IMSIs from every device in the area. This is often used during protests, in order to identify those who attend them.

Rayhunter is a piece of software that detects the presence of cell-site simulators, making attendants of protests aware of the hidden danger.

This is especially important, now that the US basically transformed into an authoritarian state. We've already seen how Trump strategically uses law enforcement to crack down on protests, such as the BLM movement in 2020. (https://www.youtube.com/watch?v=K_a63r5Km9I) Being aware of law enforcement/intelligence operations that try to identify and track down protest attendants is more important than ever.

They do this so consistently at protests, the Georgia AG tried to claim it showed criminal intent to not bring your phone to a protest for tracking.

[–] db2@lemmy.world 24 points 1 week ago

Short version is it's a man-in-the-middle detector to see if you're being spied on, using a cheap off the shelf cellular device.

[–] MTK@lemmy.world 9 points 1 week ago

Lit lit lit

[–] Geodad@lemm.ee 8 points 1 week ago (2 children)

There used to be an IMSII detector app in F-Droid. No idea what happened to it.

[–] MonkderVierte@lemmy.ml 9 points 1 week ago (1 children)

It needed Xposed framework and worked only on some devices, which are not available anymore.

[–] Geodad@lemm.ee 2 points 1 week ago

That explains it. Thanks.

[–] Andromxda@lemmy.dbzer0.com 3 points 1 week ago

It probably needs some permissions that aren't available in newer Android versions anymore

[–] ililiililiililiilili@lemm.ee 8 points 1 week ago (2 children)

Is it necessary to get a cell plan to run the hotspot? If its just a matter of buying the $20 and loading EFF's software, I'm definitely onboard!

[–] Andromxda@lemmy.dbzer0.com 12 points 1 week ago (1 children)

Is it necessary to get a cell plan to run the hotspot?

As far as I'm aware: no. Cell-site simulators could theoretically only target devices that connect with a valid IMSI, but I kinda doubt that they are doing that. But you could get a cheap prepaid SIM, instead of an actual cell plan.

[–] Ulrich@feddit.org 9 points 1 week ago (1 children)

As far as I'm aware: no.

How does data get back to EFF?

[–] Andromxda@lemmy.dbzer0.com 8 points 1 week ago (1 children)

I couldn't find anything on that yet. I think that since the project is still in a rather early stage of development, it's more of a proof of concept. But I do know that the PCAPs are saved on the device, and you can download them onto another computer.

[–] Ulrich@feddit.org 6 points 1 week ago

I went ahead and ordered one so I guess I'll find out!

[–] db2@lemmy.world 5 points 1 week ago

I know for phones even an inactive sim works to talk to the towers enough for 911 to work. Might be the same.

[–] NOPper@lemmy.dbzer0.com 7 points 1 week ago

Doing my part!

[–] Ulrich@feddit.org 4 points 1 week ago* (last edited 1 week ago) (3 children)

Just got mine and getting this error. Would appreciate any support you nerds can give me because I don't have a Github account:

Using adb at ./platform-tools/adb Force a switch into the debug mode to enable ADB /Applications/release/install-common.sh: line 20: ./serial-macos-latest/serial: Bad CPU type in executable

Edit: Installed via Linux, here's what the UI looks like

There's now a green line going across the top of the display and apparently if it detects any problems the line will turn red. Still no idea how I get that info back to the EFF though.

[–] Andromxda@lemmy.dbzer0.com 2 points 1 week ago (2 children)

Bad CPU type in executable

Do you use an Apple Silicon Mac by any chance?

[–] Ulrich@feddit.org 1 points 1 week ago (1 children)
[–] Andromxda@lemmy.dbzer0.com 1 points 1 week ago

Can I message you on Matrix to help you diagnose this?

[–] Jrockwar@feddit.uk 0 points 1 week ago (1 children)

It's the other way around, an Apple Silicon Mac would be able to run an intel binary through Rosetta (I think there's almost no exceptions at this point). It's intel macs that can't run Arm specific binaries.

[–] Andromxda@lemmy.dbzer0.com 1 points 1 week ago* (last edited 1 week ago)

You're right, I forgot about that

[–] NoSpotOfGround@lemmy.world 1 points 1 week ago (1 children)

I think it needs special hardware to run on:

It is developed to run on an Orbic mobile hotspot (Amazon, Ebay) which is available for $20 or less at the time of this writing.

[–] Ulrich@feddit.org 3 points 1 week ago (1 children)

That's what I'm trying to run it on.

[–] NoSpotOfGround@lemmy.world 1 points 1 week ago

Oh, right, you did say "just got mine"... Never mind me. It does seem like it could be a mismatch between what the adb was compiled for and what it's being asked to install on.

[–] rottingleaf@lemmy.world 1 points 1 week ago (1 children)

From what's written here, it appears you have an Intel Mac and the thing has only ARM Mac executable, or the other way around.

[–] Ulrich@feddit.org 1 points 1 week ago* (last edited 1 week ago) (1 children)

It didn't mention anything about the CPU in the install instructions...

I guess I'll give it a try on my Linux machine.

Edit: Linux install was successful

[–] Andromxda@lemmy.dbzer0.com 1 points 1 week ago

It didn’t mention anything about the CPU in the install instructions…

Try locating the binary that crashes with the "Bad CPU type" exception and run the file command on it. It will show you which architecture the binary was built for.

Edit: Linux install was successful

That's good to hear
