It\u2019s a C++ implementation of a Windows COM Context Menu Handler. The Concept: By registering a custom COM object, you can achieve persistence that triggers whenever a user right-clicks a file, folder, or the desktop background. Unlike typical \"Run\" keys, this lives within the Shell extensions, making it a bit more \"living-off-the-land.\" Any feedback, PRs, or critiques are highly appreciated!    submitted by    /u/i014n  (https://www.reddit.com/user/i014n) \n [link] (https://github.com/i014n/RightHand-Persistence/)   [comments] (https://www.reddit.com/r/redteamsec/comments/1sx1bv9/right_context_menu_persistence/)", "creation_timestamp": "2026-09-02T01:00:19.354252Z"}
