README
A Node.js package for BLE (Bluetooth Low Energy) Man-in-the-Middle & more.
## Prerequisites
see:
https://github.com/sandeepmistry/noble
https://github.com/sandeepmistry/bleno
## Install
```sh
npm install gattacker
```
## Usage
### Configure
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
### Start "central" device
```sh
sudo node ws-slave
```
Connects to targeted peripheral and acts as websocket server.
Debug:
```sh
DEBUG=ws-slave sudo node ws-slave
```
### Scanning
#### Scan for advertisements
```sh
node scan
```
Without parameters scans for broadcasted advertisements, and records them as json files (.adv.json) in DEVICES_PATH
#### Explore services and characteristics
```sh
node scan
```
Explore services and characteristics of chosen peripheral.
Saves the explored service structure in json file (.srv.json) in DEVICES_PATH.
### Hook configuration (option)
For active request/response tampering configure hook functions for characteristic in device's json services file.
Example:
```javascript
{
"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: 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
### Start "peripheral" device
```sh
node advertise -a [ -s ]
```
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.
## MAC address cloning
For many applications it is necessary to clone MAC address of original device.
A helper tool bdaddr from Bluez is provided in helpers/bdaddr.
```sh
cd helpers/bdaddr
make
```
wrapper script:
```sh
./mac_adv -a [ -s ]
```
## Dump, replay
Dump files are saved in a path configured by `DUMP_PATH` in config.env (by default `dump`).
More info:
https://github.com/securing/gattacker/wiki/Dump-and-replay
## Troubleshooting
Turn off, cross fingers, try again ;)
### reset device
```sh
hciconfig reset
```
### Running ws-slave and advertise on the same box
With this configuration you may experience various problems.
Try switching NOBLE_HCI_INTERFACE and BLENO_HCI_INTERFACE
### hcidump debug
```sh
hcidump -x -t
```
