A question for anyone who has made their own, working, #rayhunter from an #orbic #rc400l ...
After reading the #EFF material, there doesn't seem to be any conclusion on whether an active #Verizon #SIM card is needed to process cell tower signals for analyzing. Can someone confirm either way if one is required?
Additionally, does the Orbic need to be officially unlocked for RayHunter to work?
Man, the kit it takes to visit Minneapolis is a chore…

Shoutout to the @eff!
Just got my hotspot in the mail and installing #Rayhunter couldn't have been simpler.
Can't wait to try it out!

Meet Rayhunter: A New Open Source Tool from @eff to Detect Cellular Spying
The Electronic Frontier Foundation has released an #opensource project called #Rayhunter. It is designed to run on an inexpensive (~$20) mobile hotspot and look for signs of mobile spying devices called cell-site simulators. Also known as Stingrays or IMSI catchers, they masquerade as legitimate cellphone towers, tricking phones w/in a certain radius into connecting to the device rather than a tower.

My Orbic RC400L arrived to install Rayhunter on. I can tell this will take a lot of time understanding the more important parts of the LTE RRC protocol because I have no idea what I’m doing.
Hopefully some more interesting data will appear tomorrow when I have it record the drive to the office.

I was not expecting this to arrive so quickly, but it’s here and I already have #Rayhunter installed on it. Going to take it out for a drive this evening.
I think this has some value above and beyond catching stingrays because of what it collects when recording. :)
A New Tool to Detect Cellular #Spying | EFFector 37.3
This edition of the newsletter covers our new open source tool to detect cellular spying, #Rayhunter ; The #Foilies2025 , our tongue-in-cheek awards to the worst responses to public records requests; and our recommendations to the #NSF for the new #AI Action Plan to put people first.

A note on the name: Rayhunter is named such because Stingray is a brand name for cell-site simulators which has become a common term for the technology. One of the only natural predators of the stingray in the wild is the orca, some of which hunt stingrays for pleasure using a technique called wavehunting. Because we like Orcas, we don’t like stingray technology (though the animals are great!), and because it was the only name not already trademarked

@eff #opensource project #Rayhunter…runs on an #Orbic mobile hotspot…<$20…
We hope #activists, #journalists…help us collect data about the usage and capabilities of #cellsitesimulators…
…works by intercepting…and analyzing the control traffic (but not user traffic…) between… Rayhunter…and the cell tower…
…notifies the user when something suspicious happens…allowing users to take appropriate action to protect themselves, such as turning off their phone…

Danke, aber wie komme ich an das Kästchen? Ist zwar schade, dass sich ein fake call nicht mit dem Handy entlarven lässt, aber auch extra HW hole ich mir gern, wenn ich mich damit effizient schützen kann.

EFF veröffentlicht Rayhunter: Open-Source-Tool zur Erkennung von IMSI-Catchern. Rayhunter spürt Cell-Site-Simulatoren (CSS) auf, die Handys täuschen und überwachen. Es läuft auf günstiger Hardware und warnt bei verdächtigen Aktivitäten.

Yay, my Orbic unit ($11.92 via eBay) came with a Verizon SIM and is up and running with @eff Rayhunter!
Net planning a journey tomorrow, we’ll see what she yields.
Je viens de commander un Orbic Speed RC400L Mobile WiFi Hotspot pour installer le logiciel de détection de l'EFF RayHunter. Je pourrai l'amener lors des manifs pour la paix à Mtl et vérifier l'utilisation par le SPVM ou GRC de stingray aka IMSI catcher aka CSS (pour cell site simulator)

Quelqu'un a réussi à acheter un joujou 4G-Wifi hotspot Orbic en France ? J'aimerai éviter Amazon (qui de toute façon ne veut pas le livrer en France) et je n'ai pas de compte Ebay. C'est pour installer #Rayhunter https://www.eff.org/deeplinks/2025/03/meet-rayhunter-new-open-source-tool-eff-detect-cellular-spying
Falls ihr auf der #mrmcd24 einen tplink-m7350 mitgenommen habt und #rayhunter ausprobieren wollt, findet ihr alle Infos dazu verlinkt in diesem Issue https://github.com/EFForg/rayhunter/issues/106#issuecomment-2706661413
Talk by the authors of the EFF #Rayhunter tool used to detect IMSI catchers (Stingrays). Talk goes from them knowing basically nothing to software implementation including under the hood details. Well worth a watch if you're into surveillance tech.
Successfully installed #Rayhunter. Works good. Don't have a stingray to test it with ... but I know who doeeeesssss. Can I leave it on record and have it save everything as I drive around? Hmm, testing testing.
Want to see the #RayHunter Stingray detector in action? See this video. It's something you can setup yourself using a $15 device.
