I think you meant the German-made Cryptophone 500, not Blackphone. http://www.wired.com/2014/09/cryptophone-firewall-identifies... I recently discovered an IMSI-catcher app on the F-droid market for Android. It's called Android IMSI-Catcher Detector and you can easily find it in the Security category if you filter by it in the app. For some reason, I can't browse for it on the site. The project is in alpha stage and seems to be this one here: https://github.com/SecUpwN/Android-IMSI-Catcher-Detector There's also this paper on making IMSI-catcher detectors: https://www.sba-research.org/wp-content/uploads/publications... I hope to see more people working on this, though. In fact, I wish Google, Apple and Microsoft would add protections against IMSI-catchers by default in their mobile operating systems.

Calling all Hackers and Security-Geeks out there!

That is exactly the reason why we keep this porject as open-source as possible, have a disclaimer for it which basically tells YOU to be responsible what you do with the code and most importantly, we are on NO STORE, especially not GooglePlay. If an App moves to GooglePlay and does something that not plays by the rediculous "rules" (serach for what happened to the awesome HushSMS), they're kicked. If any store, then F-Droid. But for now, why not just grab the most recent compiled WIP-Release from here and give it a shot? https://github.com/SecUpwN/Android-IMSI-Catcher-Detector/rel... Also, as much as I appreciate your comment just to find this thread later on, this is NOT the official discussion of the App. I HIGHLY recommend just starring the GitHub and (if you have balls) contribute to it's success by submitting pull requests.

Of course law enforcements won't like the Project. Of course there will always be people in this world who think they can do whatever they want, when they want it and kill people using fully automated drones with IMSI-Catchers on board. But why should we think we "can't do anything"? We are the people, we have RIGHTS! So grab your balls and contribute!

Hello, everyone! Since Google does not seem to be interested in fixing the huge security hole of not showing a ciphering indicator on Android, it appears as if they get paid (or are forced to) not fix it. For all of you that are sick of getting spied on through IMSI-Catchers, Silent SMS and alike and want to do something about it, here's a great project you should check out: "The Android-IMSI-Catcher-Detector" (AIMSICD). It is an Android open-source based project to detect and (hopefully one day) avoid fake base stations (IMSI-Catchers) or other base-stations (mobile antennas) with poor/no encryption. This project aims to warn users if the ciphering is turned off and also enables several other protection-mechanisms. Since it is under constant development, they are constantly searching for testers and security-enthusiastic developers with
