Breaking (Bad) Cross-Site Request Forgery Protection – The Netgear Nighthawk M1

What is CSRF? Cross-site Request Forgery CSRF is a descriptive term, but pretty oblique if you don’t know exactly what it means. Broken down, it’s pretty simple: A malicious web page running in your browser can send requests to other sites. When it sends those requests, it’ll use the current...

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...
