Visit next lesson to learn How to prevent MAC flooding attacks by configuring port security in Cisco Switches. Port Security is a feature of Cisco Switches, which give protection against MAC flooding attacks. How to prevent MAC flooding attacksĬisco switches are packed with in-built security feature against MAC flooding attacks, called as Port Security.
The attacker will be able to capture sensitive data from network. Start macof utility: rootCompaq8510w brezular macof. We have Cisco Catalyst 2960 (WS-C2960-8TC-L) with 8 FastEthernet ports and FastEthernet 0/1 is conected to laptop Compaq 8510w with Linux Fedora 13 and dsniff installed. It is time to make our first MAC flooding attack. Now, what is the benefit of the attacker? The attacker's machine will be delivered with all the frames between the victim and another machines. a) The first MAC address flooding attack. Frames are flooded to all ports, similar to broadcast type of communicaton. Once the switch's MAC address table is full and it can not save any more MAC address, its enters into a fail-open mode and start behaving like a network Hub. I therefore decided to build my own alternative, macof.py, available here.
#MAC ADDRESS FLOODING ATTACK MACOF UPDATE#
However this tool is old, seemingly unmaintained (last update in 2000) and I find it quite inefficient for the task.
#MAC ADDRESS FLOODING ATTACK MACOF FOR MAC#
The switch can not save any more MAC address in its MAC Address table. The traditional tool for MAC table overflow attack is macof from the dsniff project. Switch's MAC address table has only a limited amount of memory. Flood MAC Address Macof Tool Tool Kali linux Version rootbt: macof -h Version: 2.4 Usage: macof -s src -d dst -e tha -x sport -y dport -i interface -n times Example ( Generate MAC Address Interface eth1 10 ): rootbt: macof -i eth1 -n 10. Within a very short time, the switch's MAC Address table is full with fake MAC address/port mappings. The router sends a deauthenication frame to the device telling it that it has been disconnected. This means that a device is on the network that shouldn’t be connected to the network. This is a type of attack which targets the communication between router and the device. This type of attack is also known as CAM table overflow attack. Although they're extremely easy to carry out (most Ethernet adapters permit their MAC address to be modified), MAC spoofing attacks come with a significant drawback: Unlike MAC flooding attacks, they have the potential to cause an immediate denial of service (DoS) to the spoofed host. Forcing a device to disconnect from WiFi using a deauthentication attack. The intention is to consume the limited memory set aside in the switch to store the MAC Address Table. MAC address flooding attack (CAM table flooding attack) is a type of network attack where an attacker connected to a switch port floods the switch interface with very large number of Ethernet frames with different fake source MAC address.įollowing images shows a Switch's MAC address table before and after flooding attack. In a typical MAC flooding Attack, a switch is fed many Ethernet frames, each containing different source MAC addresses, by the attacker.
