If the attacker gain access to LAN where the target Server is connected. Then following mechanisms can be combined to attack target web server.
MAC spoofing + MAC flooding + ARP Spoofing. MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface. Switches maintain a MAC table that maps individual MAC addresses on the network to the physical ports on the switch.
The Address Resolution Protocol is a widely used communications protocol for resolving Internet layer addresses into link layer addresses.
Step1: Using MAC spoofing software to change attacker machine MAC address.
Step2: Generate traffic to different destination.
Step3: Repeat Step 1 & 2, This intern flood Switch CAM table and flush all exisiting entries including legitimate entry for the target server.
Step4: Bind target web server MAC address to attacker machione using MAC spoofing
Step5: Now we can initiate MIM or other attacks.
