What it detects

This rule detects Directory Service event 1644 recording an LDAP search that combines the SOAPHound style negated false filter with a security-descriptor SDflags value of 0x7. This filter construction is used to return every object with its security descriptor in a single sweep, so its presence indicates automated bulk Active Directory collection over ADWS.
