SSH into Blackberry OS10

blackberry
I own a BlackBerry Q10. It's an amazing smartphone. I've owned two Blackberries in the past. The good old Curve 8520 and a decent, but not that great, Torch 9800. On the way I got my hands on Samsung Galaxy Nexus, probably driven to Android by curiosity, but got back to BlackBerry anyway. It's probably because of the straight, candy-less user experience, amazing QWERTY keyboard, connectivity, BBM and, now, irreplaceable, BlackBerry Hub.

Since any BlackBerry with OS10 runs QNX, a Unix-like real-time operating system, I thought it might be worthwhile trying to get under the hood. What triggered my search for way to access the system from the back-door, was the need to extract data from my Google Authenticator app and idea to have a look under the hood. While the process is easy on Android systems, I couldn't find a way to access my Blackberry in any of the described ways (duh! it's a different system!). What is more, BlackBerry devices cannot be rooted as such, or at least, I couldn't have found a way to do so. Thankfully, BlackBerry has s Native SDK tools - Momentics IDE, available as a free download on RIM's website, that make it easier to access QNX layer.

Once I've installed the SDK, all I had to do was to enable Development Mode on my BlackBerry and plug it into my PC. Since I'm running Linux, the device is not recognisable "out of the box". To make it communicate with Linux machine, you have to change Access to Storage settings for USB Connections. This has to be changed from "Autodetect" option to "Connect to Mac":

Connect to BlackBerry

After this step, I plugged USB, and BlackBerry device was recognised by Linux perfectly.

The Momentics IDE gives the ability to connect to Blackberry OS 10 using SSH, using a built in terminal. I set up connection with the device with Development Mode password.

Now, I could either use the built-in terminal with "Launch SSH Session" option or move to Linux terminal.The IDE GUI lets you have it all in one place; it also provides information on running processes, memory, etc.

BlackBerry Momentics

As I'm more of a console type of user, I've decided to use terminal anyway.

From the terminal, I generated a 4096 bit key for SSH. Smaller keys just won't work:

% ssh-keygen -t rsa -b 4096 
Generating public/private rsa key pair. 
Enter file in which to save the key (/home/bubbl/.ssh/id_rsa): /home/bubbl/.rim/bbt_id_rsa 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/bubbl/.rim/bbt_id_rsa. 
Your public key has been saved in /home/bubbl/.rim/bbt_id_rsa. 

By default, SSH is not listening on BlackBerry device. To start the daemon from console, I used <mark>blackberry-connect</mark> command, found under <mark>/path/to/bbndk/host_xx_x_x_xx/linux/x86/usr/bin/</mark>. It uploads public SSH key to the device and starts the SSH daemon on the other side. -password option is the Development Mode password:

% ./blackberry-connect 169.254.0.1 -password somePassword -sshPublicKey ~/.rim/bbt_id_rsa.pub 
Info: Connecting to target 169.254.0.1:4455

Info: Sending ssh key to target 169.254.0.1:4455 
Info: ssh key successfully transferred. 
Info: Successfully connected. 
This application must remain running in order to use debug tools. 
Exiting the application will terminate this connection.

You can connect to your device using Wi-Fi as well, all you have to do is to enable Access using Wi-Fi under Storage and Access settings menu. In second terminal window (as the blackberry-connect must remain running), I checked if SSH is working on the device:

nmap 169.254.0.1 
Starting Nmap 6.00 ( https://nmap.org ) at 2014-06-10 22:49 BST

Nmap done: 1 IP address (1 host up) scanned in 10.61 seconds

Now, I could connect to my Q10 with SSH from terminal with devuser user:

% ssh -i ~/.rim/bbt_id_rsa devuser@169.254.0.1

Now I can do more exploring of the QNX system. For now, not much can be done, as the <strong>devuser</strong> account isn't allowed to do much - this is a development account used for testing purposes. I cannot find a way to SSH into BlackBerry using other accounts, such as root or default 1000 user.

% ssh -i /home/bubbl/.rim/bbt_id_rsa 1000@169.254.0.1 
Permission denied (publickey,keyboard-interactive).

The thing is that the BlackBerry SSH daemon not exactly SSH daemon per se. The device relies on SDK tools and Development Mode. The daemon is launched in background once the SDK tools are run. Alas, without the development mode, SSH doesn't work:

Info: Connecting to target 192.168.1.7:4455 
Info: Authenticating with target 192.168.1.7:4455 
Error: Connection refused: Development mode is not enabled on the device.

And, without root access there is little chance of implementing openssh server on the device. So much for extracting any data from applications, or doing much with the QNX terminal. I guess it's because QNX is a commercial, not open-source, Unix platform. For the time being I can run vi on my device though.
