ClickFix Malicious ZIP Extraction and Execution
Detects the specific sequence of commands used in the ClickFix FakeCaptcha attack, moving a ZIP from Downloads, extracting it via tar, and silently executing a batch file. This rule looks for `cmd.exe` processes that contain `move`, `Downloads`, `tar`, `start`, `-xf`, and `/min` in their command line, along with specific payload filenames like `update.zip`, `u.zip`, or `update.bat`.
