According to statcounter (gs.statcounter.com/os-versio…), about 45% of Windows machines are still Windows 10. If this is you and you don't have Extended Security Updates, @0patch is your only other source of Windows 10 security patches. Check it out!

Also, shoutout to a fantastic reverse engineering and analysis tool esReverse by @eshard, which helped us perform this, and many other analyses. To my knowledge no other tool comes close to its capabilities, and we're using just a small subset for our needs. eshard.com/esreverse

By me @Forbes: With thanks to the great @mkolsek and his team @0patch, the strange case of a zero-day uncovered during the creation of a patch for a vulnerability discovered while looking at another patch for something else. Glad I could clear that up for you... #infosec forbes.com/sites/daveywinder…
