      Remember earlier this year, all the drama about AMD CPU flaws - we should follow that up. A thread.

      The website, http://amdflaws.com , is gone. It redirects to http://cts-labs.com , which makes no mention of the issue. As far as I can establish the company is MIA.

      When the story broke in March the website had a disclaimer saying the researchers may have stocks in AMD, which was never clarified, with positions to short stock. In actual fact the stock shot up in value.pic.twitter.com/d0e8bM1SCd

      The researchers didn’t inform AMD until just before publication as they claimed AMD would never fix the issues. AMD did fix the issues. At the same time as website went live an investment website for shorters issued a large report saying the chips would have to be destroyed (??).

      The moderator of /r/netsec somehow got paid over 10k to back up the research in the press, which fed into breathless press stories at the time. Did seem weird everybody involved had a financial incentive.

      This was fully disclosed in our blog post, and I stand behind everything we said. I think it's unfortunate how it played out in the press, however, I think we were one of the only voices of reason through it all. https://blog.trailofbits.com/2018/03/15/amd-flaws-technical-summary/ …

      Second, we weren't paid to "back up" anything to the press. We were paid for a thorough technical investigation of a piece of software. No one can pay me to lie, or hype anything and then promote it on their behalf.

      Third, you'll note that even AMD cited our public analysis of the vulnerabilities in their reporting: https://community.amd.com/community/amd-corporate/blog/2018/03/21/initial-amd-technical-assessment-of-cts-labs-research … I'm not sure how you think I should have acted differently?

      I was not even paid to write our blog post about those flaws. I wrote it because I felt the press around it was getting out of hand.

          I’d be interested to know if anybody from press investigated who paid for the research (CTS Labs at the time declined to name the company) as I think that had a big impact to how the disclosure played out. The archive of the website is hilarious in hindsight.
