I was reading around about UEFI and SecureBoot, according to what i found on internet, i understand that UEFI is easy to bypass in general, the real security is SecureBoot feature, are there any bootkits that bypass SecureBoot so far ? And to what kind of attacks SecureBoot is vulnerable, i was reading something about writing malware code to non SecureBoot chips or evil twin OS but i didnt understand in details.
SecureBoot is only effective if you can guarantee that the UEFI bios is not changeable. If you can inject your code into UEFI, you can overcome all the checks.
