I would particularly like to highlight the work of Dataflow Forensics and their much more advanced work dissecting SPTM without the benefit of source code. I enthusiastically await their promised blog post about exclaves and hope they will answer many of the remaining questions, provide gory disassembly explanations, and correct all my mistakes and assumptions!
Yes, they're saying that there's some stuff they didn't cover, and they hope the Dataflow people will. But the first couple didn't really answer much so I'm not particularly hopeful.
That is underwhelming! (But also.. that's *this* discussion.. and the other discussion is already linked by GP.. so I'm not really sure what you're aiming for here)
P.s. @gnabgib thanks for all your excellent dupe postings! I used to do a lot but life got busier. You are appreciated.
Edit: @thrdbndndn: My bad, yes this submitted article is the one that sucks. Thank you! If you delete your reply it will make things less confusing, but no worries and best wishes.
