What it detects

This rule detects WinRAR or 7-Zip archiving with a password and document file-type filters, a collection and staging pattern that gathers sensitive files for exfiltration. This was catalogued among data-exfiltration TTP binaries. Password-protected archives scoped to office document types typically indicate deliberate data staging before theft.
