| Description | Finding 4: Unauthorized Firmware Installation via Spoofed OTA Updates
The device lacks robust validation of OTA firmware updates.
Although some built-in safeguards and validation checks exist, they can be bypassed.
An attacker can spoof the update server and deliver malicious firmware, which the device may accept as legitimate.
This could enable full device compromise and manipulation of charging behavior.
