What it detects

This rule detects archive or compression tooling on macOS creating output under the /tmp directory. The infostealer staged stolen browser and credential data into a hidden /tmp subfolder before compressing and exfiltrating it, so archive creation targeting /tmp is an indicator of local collection ahead of data theft.
