*Hardware hacking meets extreme privacy.* A Go script that connects to a cheap smartwatch via Bluetooth, monitors your heartbeat, and **wipes your browser history if it thinks you're dead**.

## ⚠️ Disclaimer & PoC Notice
This project is strictly a **Proof of Concept (PoC)** built for educational and hardware hacking purposes. 
* **OS Support:** It runs **ONLY on Linux**.
* **Hardware:** The payload injection, handshakes, and GATT characteristics were specifically reverse-engineered and tailored for the **Zeblaze GTS 3** smartwatch. 
* **Risk:** Use this software at your own risk. The author is not responsible for any accidental data loss if the watch disconnects, the Bluetooth adapter fails, or the sensor misreads your vitals.

## ⚙️ How it Works

The script acts as a Dead Man's Switch tied to your vital signs:

1. **BLE Connection:** Uses the `go-ble` library to connect to the smartwatch via Bluetooth Low Energy (BLE).
2. **Reverse Engineering / Magic Payloads:** It sends specific hex payloads to perform handshakes, sync time, and force the activation of the smartwatch's heart rate sensor.
3. **Monitoring:** It listens for notifications on the Heart Rate GATT characteristic (UUID `2A37`).
4. **The Trigger (Dead Man's Timer):** A 30-second countdown timer starts. Every time a heartbeat is received, the timer resets.
5. **The Execution:** If the watch stops sending heartbeats for over 30 seconds (or if the connection drops and isn't recovered), the script assumes you've passed away and executes the emergency function: **permanently deleting your Chromium history file** (`~/.config/chromium/Default/History`).

## 🛠️ Prerequisites

To run this project, you will need:

* **Go** (version 1.25.0 or higher)
* **Operating System:** **Linux ONLY** (The script relies on the `ble/linux` device implementation).
* **Hardware:**
  * A working Bluetooth adapter on your PC.
  * A **Zeblaze GTS 3** smartwatch (using another watch will require you to reverse-engineer its specific handles and payloads).
* **Browser:** Chromium or Google Chrome (for the wipe function to hit the default file path).

## 🚀 How to Use

1. **Clone the repository:**
   ```bash
   git clone https://github.com/xelckis/dead-mans-jank.git
   cd dead-mans-jank
   ```

2. **Find your watch's MAC Address:**
   Use tools like `hcitool`, `bluetoothctl`, or mobile apps like *nRF Connect* to find the MAC Address of your Zeblaze GTS 3.

3. **Edit the code:**
   Open the `main.go` file and change the `mac` variable in the `main()` function to match your watch's MAC Address:
   ```go
   mac := "6C:C1:7F:1A:89:43" // Replace with your MAC Address
   ```

4. **Download dependencies:**
   ```bash
   go mod tidy
   ```

5. **Run the script:**
   *Note: Running BLE operations on Linux usually requires root privileges.*
   ```bash
   sudo go run main.go
   ```

## 🧠 Technical Details (GATT Services)

The script interacts with the following main UUIDs:
* **Service:** `180d` (Heart Rate)
* **Characteristic:** `2A37` (Heart Rate Measurement)
* **Hidden TX UUID (Handle 0x0045):** Used to inject the sensor activation commands and "Keep Alive" pings (`0xFE, 0xEA, 0x10...`).
