At one point in time I had a conversation about how I would put a hardware implant into a system. I'm delighted to see @qrs had a very similar assessment:https://twitter.com/qrs/status/1047910169261330432 …
If it ain't broke, I'll fix it!
I'm porting Linux to Apple Silicon Macs at @AsahiLinux.

Given a photo of a server motherboard, this was my response after a few minutes. You'll have to take my word i wrote this 4 Sept 2017. " Well, you picked an easy one, it already has a backdoor :)"pic.twitter.com/GYRWkXpE9g
"The ASPEED chip (1) is the BMC or Board Management Controller. It's an extra CPU on the system that is supposed to 'manage' the actual server that does all the work, like negotiating power supplies and storage connections with the rest of the servers in the rack."
"The ASPEED chip is likely running an ancient, outdated linux kernel that has documented vulnerabilities. Even if it is not, it's entire firmware is stored on a simple 8 or 16 pin chip (2 or 3, most likely #3)"
"In the event that wouldn't work, the other chip (probably #2) is almost certainly the PC bios. You can add a bootkit that loads some code at boot and configures it to be run once the operating system has loaded."
"there's a space (4) for yet another chip. From the looks of it it might be an alternate place for the PC bios (2) in case they wanted to cut costs and use an 8 pin part instead of a 16 pin part, but it could have a different purpose"

The BMC flash is the larger IC, because it has to contain an OS and all the BMC functionality, hence why they use a physically larger package (to accomodate a larger die). I cross-checked with other Supermicro boards and which is which is clear on others.https://twitter.com/marcan42/status/1047806561760890880 …

Yeah. Makes it a pain because they're often 32MB+ and flashrom doesn't do 4-byte addressing.. That's what got me to just using python and libmpssehttps://github.com/devttys0/libmpsse …
