A Node.js package for BLE (Bluetooth Low Energy) Man-in-the-Middle & more.
This repo has been patched to compile on Linux with NodeJS v10 as most of the dependencies were abandonware and failed ot compile. (Works on RaspPi 3 and 4 as well as many others.)
#Add Nodejs 10 to apt sources
curl -sL https://deb.nodesource.com/setup_10.x | sudo bash -
#Install Nodejs v10
sudo apt install nodejs -y
#Install Dependencies
sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev build-essential -y
#Install Node-gyp globally
sudo npm install -g node-gyp
#Clone this repo
git clone https://github.com/xen0bit/gattacker.git
#Enter Directory
cd gattacker
#Install this toolkit
npm installRunning both components Set up variables in config.env:
- NOBLE_HCI_DEVICE_ID : noble ("central", ws-slave) device
- BLENO_HCI_DEVICE_ID : bleno ("peripheral", advertise) device
If you run "central" and "peripheral" modules on separate boxes with just one BT4 interface, you can leave the values commented.
- WS_SLAVE : IP address of ws-slave box
- DEVICES_PATH : path to store json files
sudo node ws-slaveConnects to targeted peripheral and acts as websocket server.
Debug:
DEBUG=ws-slave sudo node ws-slavenode scanWithout parameters scans for broadcasted advertisements, and records them as json files (.adv.json) in DEVICES_PATH
Scan may hang on first run. Hit CTRL+C and run again.
node scan <peripheral>Explore services and characteristics of chosen peripheral. Saves the explored service structure in json file (.srv.json) in DEVICES_PATH.
For active request/response tampering configure hook functions for characteristic in device's json services file.
Example:
{
"uuid": "06d1e5e779ad4a718faa373789f7d93c",
"name": null,
"properties": [
"write",
"notify"
],
"startHandle": 8,
"valueHandle": 9,
"endHandle": 10,
"descriptors": [
{
"handle": 10,
"uuid": "2902",
"value": ""
}
],
"hooks": {
"dynamicWrite": "dynamicWriteFunction",
"dynamicNotify": "customLog"
}
}Functions:
<dynamic|static><Write|Read|Notify>
dynamic: connect to original device
static: do not connect to original device, run the tampering function locally
It will try to invoke the specified function from hookFunctions, include your own. A few examples provided in hookFunctions subdir.
staticValue - static value
From a fresh start, a scan must be started and killed twice in order for advertise to work.
sudo node advertise -a <advertisement_json_file> [ -s <services_json_file> ]It connects via websocket to ws-slave in order to forward requests to original device. Static run (-s) sets services locally, does not connect to ws-slave. You have to configure the hooks properly.
For many applications it is necessary to clone MAC address of original device. A helper tool bdaddr from Bluez is provided in helpers/bdaddr.
cd helpers/bdaddr
makewrapper script:
./mac_adv -a <advertisement_json_file> [ -s <services_json_file> ]Dump files are saved in a path configured by DUMP_PATH in config.env (by default dump).

Turn off, cross fingers, try again ;)
hciconfig <hci_interface> resetWith this configuration you may experience various problems.
Try switching NOBLE_HCI_INTERFACE and BLENO_HCI_INTERFACE
