Network Sniffing - MacOs — Sigma Rule
Sigma rule adc9bcc4-c39c-4f6b-a711-1884017bf043. Network Sniffing - MacOs — Sigma Rule. Detects the usage of tooling to sniff network traffic. An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data.

Telemetry review
Read the original logsource above, then inspect the linked detection workspaces for technique-level sensor context. No per-rule telemetry equivalence is inferred.
Pinned research references. No browser attack runner, live simulation result or validated detector is asserted. Source mappings and validation limits are preserved. ATT&CK / Atomic provenance · Detection provenance.
