      This is why bug bounties MUST NOT exceed the price a developer or tester would make in salary. This is why those $250,000 bug bounties for side channel vulnerabilities are too high. We're damaging the defense pipeline w perverse incentives for bug hunters. #bountySmarterNotHarderhttps://twitter.com/tsunamino/status/975108284175679488 …

      Seriously considering finding privacy bugs for bounty money instead of running @consentsoftware which does the exact same thing for free 🤔 https://twitter.com/k8em0/status/975099668718735361 …

      You are massively underestimating the effort and cost required to develop side channel attacks. $250k is stupid cheap for a novel side channel. Absolutely no-one is quitting their day job over this bounty. And probably still wouldn't if it was 10x higher.

      Ok, pal. Like it didn't already happen at Apple, & current and former MS & chip maker employees, plus salaried penetration testers hired to find these, aren't right this minute weighing their options.pic.twitter.com/EqKmW772mL

      AFAICS there are several things that make that a very unattractive option in this case: - these bounties are bounded to ~1 year - Intel excludes ex-employees for 6 months - you get nothing if another researcher beats you to it - you get nothing if Intel/MS beat you to it

      to me, your points seem more applicable to bounties for normal software bugs than to this specific case

          Twitter isn't the place to debate this. I've been saying that there's a point where bug bounties won't get you what you want. Go too high, you kill your hiring pipeline. Higher skilled folks don't want to gamble, exactly right. This is the price point of perverse incentives.

          Come on Katie -- you don't get to start a Twitter thread with a strong opinion and then state that Twitter isn't the place to debate this. Or, rather, you do -- but the optics are pretty rough to the bystander :)
