Lateral Movement

Endpoint Impersonation Limited by 802.1X

T1557 · MITRE ATT&CK

Impersonate an authorized endpoint on a switch port configured for MAC Authentication Bypass (MAB) by setting the attached interface to that endpoint's enrolled MAC address. This can obtain only the access policy associated with that MAC when the switch and RADIUS policy accept MAB, including as a configured fallback after 802.1X failure. Cloning a MAC address alone does not satisfy EAP-based 802.1X authentication.
