The problem is Android itself. Thanks to Xprivacy, it's a lot easier to control what leaks out of your device. Personally I'd rather see more encryption mechanisms than this. FFOS seems to be on the right path

There Is nothing you can do to stop identity theft.


And there is nothing you can do to do the government from tapping your lines.

You want a safer form of communicating, send Voice recordings over text.

That's an entirety separate warrant, and harder to get. Other than that. It's hopeless

I think you mean FOSS[1] = Free and Open Source Software. Anyway, I fully agree, in fact, that is the ONLY way. Closed source encryption programs can't be 100% trusted by definition. There might be security flaws, intentional or not.

Anyway. the NSA has backdoors to every operating system[2], so if you're really a target, they get you. Also, there are more than enough security holes in the layers under the operating system[3].

I think what these phones are supposed to do is bring end-to-end encryption for e.g. industry users so they don't get spied on. The NSA and the US government can get their hands on encryption keys for servers like in Lavabits case[4]. But this is the transport encryption. The data is, if not otherwise secured, available in plain text on the servers of providers. This also means, the officials can decrypt ANY data that comes in, not just the one of actual targets.

Now, end-to-end encryption makes sure even the provider can't see your data in plain text because you encrypt and decrypt it on your device. What Blackphone does is, it uses the apps from Silent Circle, a closed source encryption programm for VoIP and messages. Although the owner of that company is the well trusted cryptographer Phil Zimmerman, one can never be sure.

That's a good point. how a non blackphone device is gonna decipher the encryption? how is it going to get the key? How can a non blackphone device even a establish the same "secure" connection?
You can install and use Silent Circle on any(ok, a lot of) phone(s). Just make sure you don't have additional malicious software installed. Any yes, it costs $100/year or so. And you get a subscription for SpiderOak, sort of a Dropbox but they encrypt the data before uploading. Any you get a better overview over what app uses what permissions. A few extra tweaks basically.

Alternative: Android Phone with CyanogenMod/Replica. TextSecure for messages, RedPhone for VoiP and owncloud for files. Way cheaper too, and open source, also made by well respected cryptographers like Moxie Marlinspike[5]

Question More info?

Hi all - looking for more info on this phone - just joined XDADev to post this.

Specifically, what brands might this hardware be found under? Know it's a Tinno S8515 but have yet to find out anything about that; seems like Tinno generally makes phones for other companies?

Any help is appreciated!

The greatest challenge to securing a phone is not the OS or the apps running on it, it's the baseband. We have known for well over 30+ yeasr how to harden a *nix based system (like AOS), but we haven't even started to question WTF is going on in the closed source 10-100 MB baseband RTOS, which have fulll access to your entire FS and the most important phone operations, like SIM, RF, EMMC etc etc.

Only forcing the corrupt modem OEM's to release the sources of the Baseband firmware could improve the situation. This will never happen, unless there is another baseband Snowden out there somewhere...

We already know that the BP/CP FW is extremely insecure, and relies almost solely on obscurity as their main mechanism of protection. If this was not the case, the iPhone unlock developers would have been fekked long time ago, and the rest of us would sit around with SIM/network locked bricks filling up our bookshelves.

Unfortunately the greatest majority of the millions of XDA members are completely carefree about this issue and are only happy as long as they can "tweak some ROMs". So this will never be the place to find/see any serious baseband reversing, no matter how important it would be from a security standpoint.

So to summarize, your Qualcomm baseband will continue to send your exact GPS coordinates to the network provider at will, without you ever knowing, and without anyone (here) caring. So goes for the FM transmitter that is part of the baseband FW in both Intel and Qualcomm based phones. Do you have control over that? Never.

Only a serious long term spectrum analysis study could reveal whats going on there, where and when you're not (able) to watch.
