      I would like to thank @msftsecresponse for the bounty. Just days before Ramadan. https://twitter.com/waleedassar/status/1377606227249729537 …pic.twitter.com/GJ6ZgrKepJ

      I am happy for your bounty, looks like my message came through. Any bsod triggered by opening a path can easily be made into a remote. When i submitted \\localhost\mailslot: open giving bsod it was 0 bounty. Apperently the only way to get your message through is by mayhem :)

      They're paying bounties for BSoD? That's a new one. Or was this for another bug?

      Yes, since @jonasLyk found a new attack vector for such kernel bugs with “minimal user interaction”.

      From remote presumably? Is this documented? Just curious :-)

      I see, still doesn't explain them paying for it. Traditionally they'd mark that as a reliability issue, not even security. But hey, get them to pay while before they change their mind. Hopefully it won't end up like the great symlink bounty scandal😆

      I spiced it a bit up with a POC with .url file where the icon points at the path. I made it for the volume corruption bug, but also gave bleeping computer a POC that just BSOD - the rest is history. But yarh, now they gotta pay up for this kinda BSOD.

          Well it doesn't require much imagination to work out that you can abuse .url or .lnk files and similar if you have a bug where just poking a file path causes a crash. Sadly, the one thing I can say with certainty is MS lacks such basic skills :-)
