Brador is the first known backdoor for the Pocket PC hand-held devices.
When run, the backdoor copies itself to startup folder, mails the IP
address of the PDA to the backdoor author and starts listening commands
on a TCP port. The hacker can then connect back to the PDA via
TCP port and control the PDA through the backdoor.
Brador has not been seen in the wild. It only runs on ARM-based Pocket PC
devices that have Windows Mobile 2003 (Windows CE 4.2) or later.
Brador is a backdoor, not a virus. It will not spread on it's own.
Disinfection
Disinfection with Anti-Virus for Pocket PC
Run the F-Secure Anti-Virus for Pocket PC delete infected files and
reboot the device.
Manual disinfection
Or if you need to do it manually, delete svchost.exe from Windows\StartUp
directory with the Pocket PC explorer and reboot the device.
When run the Brador will copy itself to Windows\StartUp directory
as svchost.exe on the Pocket PC device, so that it will automatically
start at each time when device boots.
The installation routine makes slight modifications to the file
copied to Windows\StartUp directory. So the file will be a bit
different at each boot, although this will not affect the operation
of the backdoor. It is still unclear whether this is intentional
or side effect of the installation routine.
Payload
When the Brador has installed itself into the system it will read the
local host IP address and email that to the author.
After emailing it's IP address the backdoor opens a TCP port and
start listening commands from it.
The backdoor is capable of uploading and downloading files from PDA,
executing arbitrary commands and displaying messages to the PDA user.
