As FW engineer, I am both horrified and intrigued.
The fact that there are so many devices lack even basic security features horrified me. A webcam that activity light can be turned off remotely, that's a big no no for me.
But the use of LLM is also very interesting, we may put LLM in the loop to harden our devices.
Sorry community, but it's our job to make the reverse engineer harder.
If you can use a custom chip yep, if it's commodity hardware probably not. You could use secure boot/secure memory etc but that can be a footgun in itself later.
Why is your job to make the reverse engineer harder? When the user buys a product, it should be theirs to do whatever they want, even brick it. Your job should be creating the product the user wants to use, not building obstacles, otherwise you are creating something actively user-hostile. What if your company goes out of business and the user ends up with a device that can't be updated, that depends on cloud services that don't exist anymore, or worse with security vulnerabilities?
