A Node.js package for BLE (Bluetooth Low Energy) Man-in-the-Middle & more.

npm install gattacker
Running 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-slave
Connects to targeted peripheral and acts as websocket server.
Debug:
DEBUG=ws-slave sudo node ws-slave
node scan
Without parameters scans for broadcasted advertisements, and records them as json files (.adv.json) in DEVICES_PATH
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
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
make
wrapper 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> reset
With this configuration you may experience various problems.
Try switching NOBLE_HCI_INTERFACE and BLENO_HCI_INTERFACE
hcidump -x -t <hci_interface>
