i need starting ideas how to penetrate a laptop. In the scenario, i have physical possession of the laptop, and can buy equipment up to 10000 euros. I was looking at rootkits, but they seem to work only if previous root level is gained.
I would guess that the starting point would be to do changes in the booting process, but what and where?(flush with new modified bios, firmware...)
I know there are tools that replace the admin password in windows, but if this password is used for encrypting files, then the whole purpose of the hacking is lost. So, my question would be:
What is the attack surface at a turned-off laptop, (which might or might not have TPM and byte encrypted hard drive)?
