Traffic Volume Spike on Payload Channel

Monitors traffic volume or bandwidth usage on the payload communication link to detect spikes that exceed normal operational thresholds, which may indicate malicious activity.

STIX Pattern

[network-traffic:src_ref.value = 'payload_channel' AND network-traffic:traffic_volume > 'baseline_threshold']

ID Name Description
EXF-0010 Payload Communication Channel Threat actors can deploy malicious software on the payload(s) which can send data through the payload channel. Payloads often have their own communication channels outside of the main TT&C pathway which presents an opportunity for exfiltration of payload data or other spacecraft data depending on the interface and data exchange.
