What it detects

This rule detects Directory Service field engineering event 1644 recording LDAP searches that request all attributes with the SDflags control set to 0x7. SOAPHound and similar ADWS-based collectors issue these broad security-descriptor-inclusive queries to map the domain, so this search-filter signature indicates bulk directory harvesting.
