Researchers discovered that the nRF52832 Bluetooth chip leaks its AES keys through radio frequency signals. They successfully recovered the 128-bit key from a meter away, raising concerns for security in industries using this chip, especially automotive. This method could potentially apply to other BLE chips as well.

A critical vulnerability in the Bluetooth Low Energy interface of Unitree robots allows attackers to take complete control, potentially creating a wormable botnet. Discovered by security researchers, this exploit affects multiple models and highlights ongoing security lapses in Unitree's firmware, raising concerns about the robots' deployment in sensitive environments. Despite attempts at responsible disclosure, Unitree has been unresponsive, prompting researchers to publicize the issue.
