What it detects

This rule detects curl retrieving an archive named nvidiadrivers.zip into the user temp directory. The Lazarus ClickFake Interview campaign uses this command to stage its payload while masquerading as a legitimate GPU driver update. The specific archive name written to a temporary path with certificate checks disabled indicates malicious staging.
