      Alex loves repeating this, but there are two problems with his observation. 1/ The reality is that the distribution of effort lines up *really* closely with his pyramid. The volume of discussion doesn't reflect that, because phishing isn't news. https://twitter.com/Kym_Possible/status/1187414505287864321 …

      2/ Measuring impact by directly affected users is naive. Commercial exploits are used in surgical strikes against specific targets. Influencing an election, stealing financial results, etc. can impact *one* user directly, but *indirectly* many.

      We *can* work on more than one problem simultaneously, we don't have to drop everything and work on problems one at a time (I think this is a form of relative privation). Clearly, exploits cause real harm to real people, and we *should* be working on them.

          I've heard his talk a few times and it hasn't come off to me like we should drop worrying about 0-days in exchange for worrying about run of the mill attacks, so I'd say we're all in agreement with you. The concern is that naiive security orgs ignore their most real/likely threat

          Right, but it just doesn't seem like a realistic concern, what security org is hiring side-channel researchers? Malware is predominantly what naive orgs worry about, no?

          Right, lots of things cause harm to real people. The point is we should be working on all those problems, agreed?

          Tavis, the issue is that as an industry we can, but the targets have tight budgets for security and often the efforts are focused by CIOs on whatever clever hack is getting press instead of the basics which their orgs are failing at. It's really bad out here.

          I just don't buy it. What CIO is hiring academics for CPU side-channel attack research before throwing resources at malware, phishing or abuse?

          Also, researchers’ provable exploits are one of security’s key design critiques

          The way I view it is every group or individual has their own risk and threat model. Our job as researchers is to find exploits. It is up to the consumer or organization to determine if the risk is relevent to their threat model.
