Wearable devices like the WHOOP band and UltraHuman Ring are handling highly sensitive health data, yet many lack basic security measures. Researchers have demonstrated how unauthenticated Bluetooth connections can allow attackers to take complete control of these devices without user interaction, exposing personal health metrics.
You Should Know:
1. How Bluetooth Vulnerabilities Exploit Wearables
Many wearables use Bluetooth Low Energy (BLE) for communication but fail to implement proper authentication. Attackers can intercept or manipulate data by simply scanning for nearby devices.
2. Testing Bluetooth Security on Linux
Use `hcitool` and `gatttool` to scan and interact with vulnerable BLE devices:
<h1>Scan for nearby BLE devices</h1> hcitool lescan <h1>Connect to a target device (replace MAC)</h1> gatttool -b <DEVICE_MAC> --interactive
#### **3. Exploiting Missing Authentication**
If a device doesn’t require pairing, attackers can:
- Dump health data
- Inject malicious commands
- Impersonate the device
#### **4. Mitigation Steps for Developers**
- Enforce Bluetooth Secure Pairing
- Implement encrypted BLE communication
- Require user confirmation for critical operations
#### **5. Responsible Disclosure Practices**
Report vulnerabilities via platforms like **HackerOne**:
<h1>Check if a company has a bug bounty program</h1> curl -s https://hackerone.com/<company> | grep "Bug Bounty"
### **What Undercode Say:**
The lack of basic security in wearables handling sensitive data is alarming. Companies must adopt mandatory security certifications before releasing products. Users should:
– Disable Bluetooth when not in use
– Monitor device permissions
– Demand transparency from manufacturers
**Linux Security Commands for Bluetooth Auditing:**
<h1>List Bluetooth interfaces</h1> hciconfig <h1>Enable Bluetooth logging</h1> bluetoothctl show bluetoothctl scan on <h1>Capture BLE traffic (requires Ubertooth)</h1> ubertooth-btle -f -c capture.pcap
**Windows Bluetooth Security Checks:**
<h1>List connected Bluetooth devices</h1>
Get-PnpDevice -Class Bluetooth
<h1>Check Bluetooth services</h1>
Get-Service | Where-Object { $_.DisplayName -like "*Bluetooth*" }
### **Expected Output:**
A detailed security report on vulnerable wearables, including proof-of-concept commands and mitigation steps.
