• •A developer released a custom Bluetooth Low Energy (BLE) dongle on Hacker News designed for secure data injection into air-gapped systems.
• •The device utilizes AES-256 encryption to secure transfers, originally intended as a tool for moving BitLocker keys.
• •The creator is currently prototyping WebAuthn/FIDO support, noting that the existing hardware architecture already supports the necessary cryptographic functions.
• •Reliability in industrial environments and long-term security auditing of the custom firmware remain unverified.

An independent developer has debuted an encrypted BLE dongle built to simplify file and key transfers to air-gapped hardware. While similar tools like the 'Rubber Ducky' are standard in physical penetration testing, this project adds an AES-256 layer to mitigate the risks associated with open wireless transmission. The developer acknowledges the project scope expanded rapidly from a simple utility to a more complex security device, which introduces potential points of failure that standard off-the-shelf devices avoid. The utility of this device will depend on whether the developer can stabilize the planned WebAuthn support and provide a transparent audit of the custom encryption stack.
