On or off the payroll, it would seem from these comments that the exploit code is very much real. It simply wasn't exposed in the white paper.
Honestly, I very much believe that Intel has a big hand in this, personally. Whether the exploits are a reason to be alarmed or not. That said, to put a blunter point on it - screw all of them. They're all as bad as each other. AMD twist their own knives (instigating stories regarding GPP). Technology progresses, but these companies never change.
Well he was paid $16000 for some work,so OFC he was going to defend it to the end and it turns out Viceroy research said someone randomly sent the article to them,and and journalists were informed before AMD of the problem.
It makes me wonder,how many similar Intel vulnerabilities,Intel might have not patched quietly if given less than 24 hours before the disclosure.
Intel had 6 months to sort their issue out,not less than 24 hours.
Edit!!
Plus for those trying to downplay their crap - remember what if Intel or Nvidia have similar issues in the future,and some startup gives them less than 24 hours to look at them,whilst paying people and alerting the media yonks before,to try and screw over the stock price.
If this is real
https://twitter.com/c7zero/status/973668833092288513 we are only one step away (hopefully not possible) from a pretty serious exploit being possible remotely via the ARM Coretex used for the secure engine - see buffer overrun disclosure and patch around a month ago.
Maybe it is - but it also says ex-Intel employee too,and their ex-chief engineer still moans at AMD even if he does not work for Intel anymore.
Better to wait and see what the consensus is,and also for AMD to actually properly look at things.
