🇨🇳 Undocumented Backdoor Found in Popular ESP32 Bluetooth Chip, Raising Security Concerns Researchers have discovered an undocumented backdoor in the ESP32 chip, used in over a billion devices worldwide. This vulnerability could allow attackers to access data, spoof devices, and infiltrate networks. Spanish security experts found 29 hidden commands in the chip’s Bluetooth firmware. These commands enable memory manipulation, MAC address spoofing, and advanced Bluetooth attacks. Hackers could potentially exploit these functions to take full control of affected devices and move laterally within networks. If exploited, this backdoor could enable long-term persistence and spread to other devices. The lack of public documentation from Espressif raises concerns about security risks and potential misuse. ⛓ More information... #news #esp32 #security
