Website collecting info on thin clients, which many are VIA, if anyone gets interested in exploring it from a recycled unit: https://www.parkytowers.me.uk/ https://www.parkytowers.me.uk/

- blueflow 5y agoNow seeing the whole context, i feel incredibly betrayed - This was not a backdoor, but behavior documented in the datasheet. I didn't realize this 3 years ago! If this was academics, Domas' work would be plagiarism, with the 2004 datasheet being unquoted prior work: http://datasheets.chipdb.org/VIA/Nehemiah/VIA%20C3%20Nehemiah%20Datasheet%20R113.pdf http://datasheets.chipdb.org/VIA/Nehemiah/VIA%20C3%20Nehemia... (Page A-10 in the appendices)
- mhh__ 5y agoWasn't his thing about accessing it not finding it, though? We all know Intel CPUs have management engines, running doom on one would be a feat.
