Upon my return from SyScan Singapore, I needed a new research direction to kickstart my brain back into work, and this fit the bill. The core question I wanted to answer was if it was really possible for someone to build a SCBO file key generator. Understanding how SCBO files work in the first place was also intriguing. At the time I could only find a single SCBO file on the Internet, which is bad impossible to visualise differences between files but better than no file at all.
This picture shows us the full contents of the sample file. A couple of bytes later and we see another string. It appears to be some kind of serial number. 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 rest of the string and binary data that follows are unknown for now. The total file length is bytes. As previously mentioned, Apple support is able to generate these files after you provide some key information. The first digits are the machine serial number as previously described, and the last sixteen digits are a nonce value regenerated every time the firmware password is set, removed, or modified. The answer is no. If we set a firmware password on a test Mac, generate the necessary string, and modify the SCBO accordingly, nothing will happen.
This provides us with another bit of information — that there is some kind of integrity check on the SCBO contents. So if this is true then how is someone selling what appear to be fully working SCBO files? We need to dig deeper and reverse the EFI code responsible for processing this file. I maintain an up-to-date Apple firmware update repository , which you can use to easily download EFI updates or verify the contents of your EFI flash if you fear nation states are attacking you. You can use other firmware files — the GUIDs will still be the same but addresses and some content might differ.
With the payload extracted we can finally try to find where to start reversing. The initial best clue is the magic value from the SCBO file, since it should be checked somewhere in the code. My favorite tool for this type of task is bgrep aka binary grep. It allows us to grep files for specific byte sequences, an extremely useful feature to locate binary data.
