Detects privileged Active Directory enumeration seen on the wire by Corelight, filtered to source hosts that don't appear in the Cortex endpoint inventory. It reads ldap_search records from corelight_zeek_raw, tiers them by the LDAP filter (CRITICAL for credential-attribute and DCSync hunting, HIGH for Tier Zero, Kerberoast, delegation, and UAC-bitmask targeting, MEDIUM for broad group, computer, and GPO enumeration), then joins the source address against endpoints and keeps only the queries whose id_orig_h has no matching managed agent
