Can anything shield IMSI from IMSI catchers?

DeletedUser237

I suspect the price of this device will go up significantly soon.. I wonder what's the sim compatibility since it looks to be a Verizon specific device.

DeletedUser237 Yeah, just found out that it is a Verizon specific device, consequently i don't find availability anywhere in europe. Step 2 would have been finding out if it would be actually compatible with GSM in europe, and step 3 researching local laws, but since i can't find any availability in europe, i guess it ends here.

I wonder though, as in their article they aim to collect data outside of the us aswell, but currently only support that verizon specific orbic router, how they had this in mind? Perhaps there will be more devices supported as the project grows, with actual availability outside the us?

r134a I think the 'outside US' was an afterthought and they mainly focus on US.. Obviously I am not trying to shit on them on anything for that, just giving my opinion. I will most probably order one anyway and see if it is sim locked, or what's more important whether it works with the bandwidths here where I live..

I also am considering reaching out to EFF asking about the possibility to use other devices.

DeletedUser237 If u are in the position then to report back, i would highly appreciate it.

Might be interesting to some regarding rayhunter: https://www.youtube.com/watch?v=wgBJm3wRl-U

@DeletedUser237 Hi, perhaps u are keeping an eye aswell on rayhunter and u are already aware, but i wanted to let u know anyway, since u mentioned u would probably order that orbic router, there's a good chance it will be possible to run in the near feauture to run it on a device more accesible in europe: TP-link M7350.

There's a fork being created to make it run specifically for that device, and there's already a PoC it running on it: https://github.com/m0veax/rayhunter-tplink-m7350/blob/main/PoC.md

r134a Thanks, I haven't had much time to look into it further so this heads up is really appreciated. Was going to order the orbit next week, so instead will wait for the fork to mature a bit.

r134a Hey, I finally got around to order the tp link modem, will be testing it in the coming days/weeks. Will let you know how it goes. Am also interested in hearing if you have done anything with the project. Cheers

I wouldn't use one of those. The project has a thread about a lot of what's being discussed in this thread and touches on mobile routers here: https://grapheneos.social/@GrapheneOS/113319956422621755. Some relevant quotes about mobile routers are as follows:

Dedicated Hotspot devices aren't good for privacy/security.

[B]ear in mind that carrying around a Wi-Fi access point (AP) is the opposite of private. An AP has a persistent MAC even if it's random upon creating the AP such as making a hotspot with a phone. Wi-Fi does not have MAC rotation like Bluetooth Low Energy privacy extensions.

GrapheneOS uses per-connection MAC rand and per-connection DHCP as improvements over the standard Android Open Source Project. The MAC still remains the same while connected, and an AP isn't going to cycle until it's reset. Wi-Fi does not try to do what BLE privacy extensions do.

DeletedUser237 Hi, unfortunatley certain life events chose to happen shortly after eachother, consequently limiting my free time closely to 0. I didn't get any further than peeking activity once in a while on their github issue tracker, there seems to be a healthy spike in interest and collaboration though. I appreciate it letting me know and please let me know how it goes! I'm particalary interested in if there's a sim required with an active subscription or not. I'm also interested if there's yet some sort of 'notification' method for the tp-link device, other than monitoring the webui. Last time i checked on the original device there would come some sort of red line on display when 'suspicious activity' was detected, but not yet figured out on how to do the same on the tp-link device.

Cheers, have fun and thanks agian!

they don't make phones AFAIK.
I have one of their pocket MiFi devices, it is easy to use and set up, easy to add vpn etc
