ARP Spoofing via MAC Address Mismatch

ARP spoofing detected by observing that the MAC address does not match the expected authorized MAC address for the ground station.

STIX Pattern

[network-traffic:src_ref.value != 'authorized_mac_address' AND network-traffic:src_ref.role = 'ground_station']

SPARTA TTPs

ID Name Description
IA-0004.01 Ground Station Threat actors may establish a foothold within the backup ground/mission operations center (MOC) and then perform attacks to force primary communication traffic through the backup communication channel so that other TTPs can be executed (man-in-the-middle, malicious commanding, malicious code, etc.). While an attacker would not be required to force the communications through the backup channel vice waiting until the backup is used for various reasons. The backup ground/MOC should be considered a viable attack vector and the appropriate/equivalent security controls from the primary communication channel should be on the backup ground/MOC as well.
IA-0007 Compromise Ground Station Threat actors may initially compromise the ground station in order to access the target SV. Once compromised, the threat actor can perform a multitude of initial access techniques, including replay, compromising FSW deployment, compromising encryption keys, and compromising authentication schemes.
EXF-0007 Compromised Ground Station Threat actors may compromise target owned ground systems that can be used for future campaigns or to perpetuate other techniques. These ground systems have already been configured for communications to the victim SV. By compromising this infrastructure, threat actors can stage, launch, and execute an operation. Threat actors may utilize these systems for various tasks, including Execution and Exfiltration.
PER-0003 Ground System Presence Threat actors may compromise target owned ground systems that can be used for persistent access to the SV or to perpetuate other techniques. These ground systems have already been configured for communications to the victim SV. By compromising this infrastructure, threat actors can stage, launch, and execute persistently.
