🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Contact Agasta support for firmware update information. Check manufacturer website for security advisories.
🔧 Temporary Workarounds
Disable Bluetooth when not in use
allTurn off Bluetooth functionality on the ECG monitor except during active data transfer sessions
Device-specific: Use device settings menu to disable Bluetooth
Enable pairing mode only when needed
allKeep device in non-discoverable mode and only enable pairing during initial setup or authorized connections
Device-specific: Use pairing button/settings to control discoverability
🧯 If You Can't Patch
- Implement physical security controls to limit unauthorized access within Bluetooth range (approximately 10 meters)
- Monitor device connectivity logs for unusual Bluetooth connection attempts or disconnection patterns
🔍 How to Verify
Check if Vulnerable:
Check device firmware version in settings menu. If version is 3.0 and Bluetooth is enabled, device is vulnerable.Check Version:
Device-specific: Navigate to Settings > About Device > Firmware VersionVerify Fix Applied:
Verify firmware has been updated to a version later than 3.0 through device settings or manufacturer confirmation.📡 Detection & Monitoring
