The ubiquitous ESP32 microchip made by Chinese manufacturer Espressif and used by over 1 billion units as of 2023 contains an undocumented “backdoor” that could be leveraged for attacks.
The undocumented commands allow spoofing of trusted devices, unauthorized data access, pivoting to other devices on the network, and potentially establishing long-term persistence.
For those who were interested.
Yep, this lets somebody use the ESP32 as part of an attack, not actually attack them remotely.
Would be kind of silly for it to be a documented “backdoor” that was found.
