Maybe it was on GitHub/GitLab before the author was banned by both Microsoft and GitLab, not really sure we'd know. The authors last post on their blog is from yesterday (28th of May, https://deadeclipse666.blogspot.com/) so seems they aren't fully gone. But yeah, been a lot of "promises" but besides the initial 0days, not so much released AFAIK.
