Breaking (bad) firmware encryption. Case study on the Netgear Nighthawk M1

TL;DR The firmware encryption for the Netgear Nighthawk M1 is mainly XOR. It’s possible to derive the XOR key by statistical analysis, just from the firmware update file itself. It’s then possible to extract an AES key from what’s XOR’d, which can be used to decrypt other parts of the firmware...

Baldr Botnet Panel - Arbitrary Code Execution Exploit
