I've confirmed that the Orbic Speed (RC400L) Mobile Hotspot is unlocked. I have a Ting SIM in mine which was new and factory sealed and the hot spot is working (as well as #Rayhunter, which works with or without and activated SIM).

I bought 10 more of them and plan to load them and give them out to activists, organizers, and people concerned with such things. (then I wanna look into cheap meshtastic radios)

Electronic Frontier Foundation · Meet Rayhunter: A New Open Source Tool from EFF to Detect Cellular SpyingRayhunter is a new open source tool we’ve created that runs off an affordable mobile hotspot that we hope empowers everyone, regardless of technical skill, to help search out cell-site simulators (CSS) around the world.

Just updated my Orbic Hostspot with latest release of Rayhunter. Looking forward to bringing it with me to the protest tomorrow in Boston.

Anyone know if there are any off-line analysis/detection tools for the packet captures? i.e. more sophisticated detection algorithms that require more space or compute power than the device provides

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.

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
