Rooting Machines that are using BSNL EV-DO

BSNL is a Government body that offers Telecommunication and Broadband services in India. It also offers USB Modem for both rental and for owning.

This hack works on almost all the USB Modems ( ZTE EV-DO ) provided by BSNL.

EVDO is a Technology short for “Evolution – Data only” that uses 3G Technology introduced by Qualcomm.

Here i am going to share how to eavesdrop into someones Network who are using BSNL EV-DO, and using this trick you can entirely take control of the box.
This hack works only with Windows based Boxes.

Step 1 :
Install the Driver required for BSNL ZTE EV-DO Modem, as a part of the installation, it will prompt you to plug-in the device, then change the default username and password, then connect to the internet.

Step 2 :
While the modem is connected to the internet, open up a command prompt and type “Net View”
command in it, then it will display all the names of the machines that are connected to the same network that uses the similar device ( EV-DO ). It will blindly display the hostnames that are a part in that network, but it wont show whether the connected machines are alive or not.

Here is list of hostnames that was available when i was dealing with this, let it be a POC.

Step 3:
Now the major part is to find a host that is alive, and this can be done both manually and
also by using automated Batch program, once you got the host that is alive, you can connect to
its hidden IPC$ ( Inter Process Connect ) share by using the below command,

Net use \\IP-Address\IPC$ “”

in my case i used the following…..

So this will establish a NULL session with the target host that i have used, now the target system and my computer is connected, and by using we have to move further…

Step 4:
Now to check whether there is connection between your computer and the target, just type the below command, net use

This will reveal the current connections…..

Step 5:

In every windows based boxes, there must be an Administrator account, few of them will never set a password for default administrator account, and only few will do it. Now we are trying to gain Administrator access to the remote box, and this can be done by using Dictionary attack or by Launching Brute Force attack against the target.
You can compromise admin account by using Dictionary attack, and you can use the “LAN Remote
user – Dictionary Attack” tool which is already published in the site, else you can click here to check that out.

Check with the syntax properly before starting…..

Step 6:
Once you obtained the password of the administrator account, you can use the same net command
to establish a connection with administrator rights….

Net use \\IP-Address\sharename “password” /user:administrator

once you got the message “Command Completed Successfully” then you are connected to the target
machine with admin access.

Step 7:
Now goto run and type “compmgmt.msc”, this will take you to the Computer management, Click on
Action -> Connect to another computer…. and then type in the IP address or the Hostname of
the target machine.

Once you got access to the remote host, now you can see the computer management(Local) changes
to the Computer Management(XXX.XXX.XXX.XXX) – Remote IP.

Step 8:
You can now create a New user account on the remote machine by expanding the Local users and
Groups -> users -> right click there and create a new user and assign Admin rights.

Step 9:
Now you can start a Terminal Session to the remote host, or you can just start a Remote desktop connection, goto run and type MSTSC and hit enter.

Step 10:
Type in the Ip address of the remote host in the Remote Desktop connection wizard and take over the compter.

Step 11:
To cover the traces just clear all the logs in the eventviewer in the target by using the computer management itself, also make sure to delete the IPC$ connection logs by using the command

Net use \\IP-Address\IPC$ /delete

This is a high Potential Security threat… because anyone can easily gain control over the computer accross the network and can root them, Make them Zombies and later as botnets and so on.

Step 12:
To avoid being a victim to such kind of attacks, you can read the documentation submitted in dark-coderz by Clicking here.
