So from this I think you could say this is a universal microsoft secureboot implementation bypass. all you need is the signed policy file and an older more obscure (signed) non-blacklisted bootmgr and you can exploit secureboot to glory. its almost certainly going to be used for malware - a return of bootkits for invisibility/persistence? microsoft will have to keep revoking older bootmgr's as they find them in jailbreak utils and bootkit malware. eventually they will run out, but for now, busted. tempting to go buy some winRT devices for linux!
