Use of third party tools¶
Once the data has been sniffed it is possible to use third party tools in combination with Ubertooth to obtain critical info. One of the most famous third party tools includes the tool ([crackle]https://lacklustre.net/projects/crackle/).
You can install with the command :
$ sudo apt install crackle
After the installation process, the following command can be issued to obtain the keys :
$ crackle -i capture.pcap -o result.pcap
Other frameworks and tools include : bettercap and gattool.
A detailed procedure for installation, setup, sniffing, wireshark capture, followed by the use of crackle and gattool can be found on the website : Bluetooth Sniffing with Ubertooth: A Step-by-step guide
