Firmware Penetration Testing Checklist

Firmware Penetration Testing is a specialized security assessment focused on identifying vulnerabilities in the firmware layer of hardware devices. Firmware, the low-level software controlling hardware, is critical for device functionality and serves as the foundation for higher-level operations.

Test Case Name: Verify Firmware Signing
Objective: Ensure the firmware is digitally signed to prevent unauthorized modifications.

Steps:

Extract the firmware binary from the device.Verify the digital signature using the appropriate public key.Attempt to load unsigned/modified firmware.

Expected Result: Only signed firmware is accepted; unsigned or tampered firmware is rejected.

Test Case Name: Validate Firmware Hashing
Objective: Check for hashing mechanisms to ensure firmware integrity during updates.

Steps:

Extract the hash embedded in the firmware package.Calculate the hash of the extracted firmware.Compare the calculated hash with the embedded hash.
Expected Result: Hash values should match.
