This information can be verified because part of this string can be found in the motherboard of each Mac (my sample is only composed of MacBooks but I guess iMacs and others will contain the same information). The SCBO string is clearly visible in the first four bytes, which is a magic number ( 0x4F424353 ). The sample file can be downloaded here SCBOoriginal.zip. Understanding how SCBO files work in the first place was also intriguing. If this were true, it would imply that Apples EFI contains a significant vulnerability. Upon my return from SyScan360 Singapore, I needed a new research direction to kickstart my brain back into work, and this fit the bill. There are videos (in Portuguese but you can watch the whole process) of people claiming this works, and even some claims about an universal SCBO that unlocks multiple Macs. Things got more interesting when I found a website that allegedly sold the SCBO files just send them the necessary hash (more on this later), pay USD100, and get a working SCBO file in return. Since I dont have the original sales receipt of this specific Mac, I assume this option isnt possible, since anyone with a stolen Mac could get the password reset. The normal process workflow is to first contact Apple support.
