[蓝牙嗅探-Ubertooth One] 千元开源蓝牙抓包 Ubertooth One 安装和使用



前言

Ubertooth One 是一款软硬件开源的蓝牙抓包器,我们本教程将采用:学习使用、分析代码、分析硬件设计、自己制作一款抓包器的路径来展开。


1、编译 Ubertooth tools

1.1、准备工作

Ubertooth 需要用到 Ubertooth tools,该工具依赖 libbtbb (蓝牙 baseband 库),这两个工程都需要自己编译,因此,第一步需要安装为了编译上述工程的工具:

Debian 10 / Ubuntu 20.04 / Kali

sudo apt install cmake libusb-1.0-0-dev make gcc g++ libbluetooth-dev wget \
  pkg-config python3-numpy python3-qtpy python3-distutils python3-setuptools

1.2、编译安装 libbtbb

Bluetooth baseband library (libbtbb) 主要用来解码蓝牙数据包,编译安装操作如下:

wget https://github.com/greatscottgadgets/libbtbb/archive/2020-12-R1.tar.gz -O libbtbb-2020-12-R1.tar.gz
tar -xf libbtbb-2020-12-R1.tar.gz
cd libbtbb-2020-12-R1
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

1.3、编译安装 Ubertooth tools

Ubertooth 工程包含 host 端代码,主要提供:抓取蓝牙数据包、配置 Ubertooth、升级固件,编译安装操作如下:

wget https://github.com/greatscottgadgets/ubertooth/releases/download/2020-12-R1/ubertooth-2020-12-R1.tar.xz
tar -xf ubertooth-2020-12-R1.tar.xz
cd ubertooth-2020-12-R1/host
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

1.4、Wireshark 插件

建议用 2.2+ 版本的 Wireshark,自带插件。下面我写了个脚本,可以一键运行并调用 Wireshark 进行抓包。

➜  bluetooth cat ubertooth_wireshark.sh
#!/bin/bash

sudo rm -rf /tmp/pipe
sudo mkfifo /tmp/pipe

echo the mac address is: $2
echo '''
HOW TO SET WIRESHARK:
    1.Click Edit -> Preferences
    2.Click Protocols -> DLT_USER
    3.Click Edit (Encapsulations Table)
    4.Click New
    5.Under DLT, select "User 0 (DLT=147)" (adjust this selection as appropriate if the error message showed a different DLT number than 147)
    6.Under Payload Protocol, enter: btle
    7.Click OK
    8.Click OK
'''

sudo killall wireshark
sudo wireshark -k -i /tmp/pipe &

echo "reset ubertooth"
sudo ubertooth-util -r

if [ "$2" != "NULL" ];then
    echo "-t<address> set connection following target (example: -t22:44:66:88:aa:cc/48)"
    sudo ubertooth-btle -t  $2
fi

if [ "$1" == "-p" ];then
    echo "-p promiscuous: sniff active connections"
    sudo ubertooth-btle -p -I -c /tmp/pipe 
elif [ "$1" == "-n" ];then
    echo "-n don't follow, only print advertisements"
    sudo ubertooth-btle -n -c /tmp/pipe 
elif [ "$1" == "-f" ];then
    echo "-f follow connections"
    sudo ubertooth-btle -f -I -c /tmp/pipe 
else
    echo "INPUT_ERROR: sudo bash ubertooth_wireshark.sh -f BC:23:4C:00:00:01"
    exit 1
fi

echo the mac address is: $2

1.5、更新固件

当完全安装好 Ubertooth tools 之后,需要将固件更新到和上面工具软件相匹配的版本(参考第2.1节)。


2、更新及开发固件

2.1、更新固件

获取最新版本的 Ubertooth,然后解压进入 ubertooth-one-firmware-bin 目录,之后运行:

$ ubertooth-dfu -d bluetooth_rxtx.dfu -r
Switching to DFU mode...
Checking firmware signature
........................................
........................................
................

设备将会自动进入 DFU 模式然后更新固件。

注:在处于非 DFU 模式,可以用 ubertooth-util -v 获取固件的信息。


2.2、开发固件

安装支持 ARM Cortex-M3 工具链:

sudo apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi

或这直接下载:https://launchpad.net/gcc-arm-embedded

编译:

cd firmware/bluetooth_rxtx/
make

烧写:

ubertooth-dfu -d bluetooth_rxtx.dfu -r

3、效果展示

运行抓包命令:

sudo bash ubertooth_wireshark.sh -f  dc:23:4D:0c:2f:5f

自动调用 wireshark 显示数据:

: uBertooth 是一千元以下的开源蓝牙抓包器,实际使用存在一定的丢包率~
专业抓包,还要买 Ellisys 之类的几万或几十万的工具~
