Bluetooth hacking with Redfang

Searching hidden bluetooth devices with software called redfang.
This little tool will find hidden bluetooth devices but it will take a lots of time because it scan through every address from given range.
Example range 00803789EE76-00803789EEff (138 address(es)) take about 50 minutes to scan.
You can download redfang here: redfang.2.5.tar.gz

On this post I will search device:

  • 0001e364dd9b Siemens Gigaset SL2 Professional

Which should be really easy to find because I know it’s address.

So I use command fang and give it range 0001e364dd9a to 0001e364dd9d (I know that it’s just four address):



and it found my GigaSet phone called ScriptKiddie =)

When I turn on bluetooth on my Nokia Communicator E90 results will be little different:

Found: PIN1234 [00:1a:89:xx:xx:xx]

    138 address takes 50 mins…

    My question then is what real-world uses would this tool have? Even if I target a phone of a specific vendor, that doesn’t look all too promising in finding a valid MAC address in any decent amount of time…

    It’s difficult to obtain knowledgeable folks on this topic, but you sound like you know what you’re talking about! Thanks
