CVE-2024-29988Windows — the warning prompt that never appeared

A crafted file slips past the prompt Windows raises for content from outside (SmartScreen), so nothing warns the user before it runs. The catalog records it being chained with an archive flaw and a shortcut flaw to land a payload.

YOUR NEXT MOVE

Install the April 2024 Windows update. Chained with the flaws it travels with, one opened file is enough, so the control here is patching rather than user training.
