  2. UNCW NetReg

  3. NetReg Vulnerability

  4. Media Access Control address • 6-octet hexadecimal identifier • Unique to every network-enabled device

  5. Vulnerability Exploitation • Obtain the MAC address of a registered device. • Use software to change an ‘attacker’ device’s MAC address to the registered value. • Access the network using the ‘spoofed’ credentials (i.e., the registered MAC address).

  6. Retrieving Targets • Discovers IP & MAC of all machines connected to the local AP

  7. Spoofing the Target’s MAC Address

  8. Uses for MAC Address Spoofing • Legitimate:- Creating wireless connections to a network.- Better method - Changing a device’s role, from router to computer and vice-versa. • Illegitimate:- Unauthorized, stealthy access (intrusion) into a targeted restricted-access network.- Network traffic redirection.-> Obtain data from other systems on the network…
