      • Report NetzDG Violation

      So this http://AMDflaws.com  business... CTS Labs asked us to review their research last week, and sent us a full technical report with PoC exploit code for each set of bugs.

      • Report NetzDG Violation

      Regardless of the hype around the release, the bugs are real, accurately described in their technical report (which is not public afaik), and their exploit code works.

      • Report NetzDG Violation

      I initially responded to their request out of curiosity -- "Hey, do you want to see our new processor bugs before we release them?" "hell yes I do" -- but after their asks continued to grow billed them our week rate for the work.

      Dan Guido Retweeted Arrigo Triulzi

      I spent all morning talking to reporters, mostly to correct twitter hot takes. Yes, all the flaws require admin privs but all are _flaws_ not expected functionality.https://twitter.com/cynicalsecurity/status/973595697902706688 …

      Dan Guido added,

      Arrigo Triulzi @cynicalsecurity
      Now onto the “vulnerabilities”: 1) MASTERKEY: if you allow unauthorised BIOS updates you are screwed. Threat level: No shit, Sherlock! 2) RYZENFALL: again, loading unauthorised code on the Secure Processor as admin. Threat level: No shit, Sherlock!

      Replying to @chronic

      I did not see the whitepaper, video, media release, or anything else until a reporter sent it to me. Unlike everyone else, I only had the technical report and none of the media info.
