What it detects

This rule detects snmptrap sending data to the attacker-specific enterprise OID 1.3.6.1.4.1.99999, matching the Bad Apples abuse of native macOS SNMP tooling to smuggle collected data out over an alternate protocol. Encoding stolen information inside SNMP trap fields evades controls focused on HTTP and DNS exfiltration. Use of this fabricated OID with snmptrap indicates covert exfiltration.
