Fake dev-tool install page leads to malicious paste-and-run command
This rule detects potential ClickFix/InstallFix attacks where a user is socially engineered to copy and paste a malicious command from a website that mimics a legitimate developer tool installation (e.g., Claude Code, NotebookLM). The detection flags the use of common download-and-execute cmdlets (e.g., irm, iwr, iex) within common Windows shell interpreters while excluding known legitimate vendor install domains.
