      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.

      Have you had any previous dealings with CTS Labs, or the people therein? Any reason why a company like this would reach out to you in this way, before disclosing to AMD? Not trying to pick, just trying to understand if this is standard practice

      They found us through a mutual friend. I had never spoken to them before, and I have no ongoing relationship with them. They sought us out because they were concerned about the validity of their findings.

      Additional, just because I've seen people thinking you are being paid, having billed CTS for the work: Did you start investigating the issues first, then discuss billing arrangements, or did a contract come first? (People love to think everyone works for free, sadly)

      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.

          Yeah, I saw that, hence my question. Just getting a secondary confirm about the order of events to ensure no ambiguity.

          It was driven by curiosity first and a favor. However, once we received the technical report and fielded their first set of questions, we realized it went beyond a favor. We anticipated 1 bug, not 13, so we asked to get paid.
