An attacker can easily capture this communication and analyze its content, for example, in Wireshark. Subsequently, the switch will start act as an Ethernet HUB, meaning it will be forward traffic to all physical ports.

Once this table is filled, there will be no space for MAC addresses of new devices that are trying to communicate. The vulnerability lies in the fact that the size of this table is limited. Based on this table, the switch decides which port to send traffic to. Switch puts entries to CAM table where are stored MAC address and port mapping of the devices that communicate through it. MAC flooding exploits the vulnerability resulting from the basic operation of the switch.

In this article, we’ll show how this attack looks and how to effectively protect our devices against it. Tools for simulating the attacks: I would recommend using Kali linux it contains a lot of tools.Īlso here is a good article regarding tools!.MAC flooding is an attack that manipulates the behaviour of the ethernet switch so that the traffic that passes through it can be captured. But if you assume that no machine is replaced in the network then this method could help to detect the attack. What you could try is that you can make a filter for all the ARP probes/requests and then check for which source MAC address the source IP address has been changed in the ARP probes.ĭetection: This is not an ideal detection method because this could make a false positive if some one has merely replaced a machine in the network. Currently I have no idea how you can detect this attack with just a wireshark. In wireshark create a filter for ARP request to see the ARP request frames.ĪRP spoofing: In this case you shall associate your MAC address to victim's IP address by sending a specially crafted ARP frame! If the attack is successful then all traffic that was destined to Victim's IP will be now redirected to you. You can use some ARP flooding tool for simulation. But still if you have only 3-4 devices in your network and on contrast you are seeing many ARP requests with different source addresses then it could be an ARP flooding because 3-4 devices are not going to make a huge ARP requests with different source MAC addresses. This causes the switch to operate in fail open mode, which means that the switch will broadcast the incoming packet to all the ports.ĭetection: If you see a lot of ARP requests coming from random source MAC addresses, then you can assume it is ARP flooding. MAC flooding: In this attack the attacker will transmit a lot of ARP packets to fill up the switch's CAM table. In wireshark create a filter for ICMP Echo packets and check the buffer size. You can use PING command to simulate this attack. So if you see a lot of Ping packets with unusual size of buffer for eg: like 4000 then you could say it could be a Ping flood. The attacker will use the maximum value.ĭetection: The normal ping packet has default packet size of 32 bytes in case of Windows.

In windows you can specify the data/buffer size too. Ping flood: Send a huge amount of Ping packets with packet size as big as possible. A very common traditional example is Ping flood as DOS attack. (I assume you know this.) Also most of these attacks are not very common these days but for simulation and playing around it will be fun.ĭOS attacks usually send a lot of traffic to the victim machine to consume its resources so that the legit users are not able to access the services. In order to simulate attacks it is good to know about how these attacks works and how to detect them. Here is a nice paper about making a test lab. If the budget is not that big then try using virtualization tools like VMware workstation or VirtualBox etc. If you have a big budget then buy couple of systems running Windows and linux, buy some switches and connect them with network cables.

First of all I would recommend you to create a test network and isolate it from the production network.Ĭreating a test network: It depends upon your budget.
