      I imagine the public perception of BlueKeep (you know, for the 4 people that care) is it went away because people patched.. Nah, there’s just no free exploit.

      Not only public perception. A representant of a Virtual Patching solution today told me they don't have a DejaBlue protection because there's no public exploit! Not a small firm.

      I'm sure they didn't mean they don't consider DejaBlue critical until publicly exploitable but that they need a test case for a patch before they can release it. We have the same policy at @0patch: we could easily write a micropatch for DejaBlue but we need to be able to test it.

      I must say you're right, you explained it better in one tweet than their response. The worst part in my case is the presales selling that ALL the CVEs will be micropatched before the vendor (Microsoft) publish its own patches.

      ALL would certainly sound suspect :)

      almost any would sound suspect, since most patches are reversed to find the vulnerability and how to patch - so I don't know how they would make micro patches before the vendor patches are released

      In case of dropped 0days it's possible. We've done that a couple of times.

      sure, but that's a niche area, almost everything isn't a zero day

      Absolutely. Being able to (virtual|micro)patch *all* CVEs before vendors provide a fix would require unprecedented early private access to all CVE details. In other words, if you're not NSA, you can't do that :)

      I don't know, you could make a partnership with one of these firms https://www.microsoft.com/en-us/msrc/mapp . I think probably don't let Microsoft find out though, because I think they disapprove of 3rd party patching. 🤷🏻‍♂️

          Deception is not our game but yes, MAPP is on our to-do list.

          MAPP isn’t what it used to be, either. For critical issues like BlueKeep, they’re very tight lipped and don’t share much that isn’t included in public advisories. Definitely no PoC’s
