Catch a MiTM ARP Poison Attack with Wireshark // Ethical Hacking

Рет қаралды 26,800

Күн бұрын

In this video, we look deeper into a man in the middle ARP poison attack, showing how to quickly filter for it in Wireshark.
For your reference, the filter that I show you how to build in the video is this one:
((arp.src.proto_ipv4 == 10.0.0.1) && (arp.opcode == 2)) && !(arp.src.hw_mac == 11:22:33:44:55:66)
Just replace your local gateway IP and MAC address and you can use this filter to spot MiTM attacks that are posing as your gateway.
Also check out the first video in this series on how an ARP attack works.

Just when I thought I understood how to spot that in a very crude and elementary way, Chris does it with finesse and teaches you a few more things a long the way. Loved the profile trick and overall how you went about teaching and explaining this attack. 10/10

Hello Chris, I'm one huge follower and I want to share my experience here. I'm working for ISP as a tier 2 technician, your lessons on TCP and wireshark literally boosted my knowledge for double amount. And its not that I didnt know something before, but the more you dig into the packet/segment level of communication, you just realize and start breaking the puzzle. Thank you for the awesome videos, and yeah one my last case, on of mine clients was dealing with DDOS attack(qotd at udp 17), if there was no wireshark I wouldnt be able to isolate and resolve. Thanks again and keep those coming. I would like to see a video on buffer delays and how we can spot it in wireshark, and how much does it impact in the network in a first place. Cheers buddy.

@elliemagnetic6136 2 жыл бұрын

what about in the case of spoofing the mac address in the malicious arp request, or even changing the mac address of the hackers machine to that of the gateway?

@ChrisGreer 2 жыл бұрын

That is a great question. If the attacker spoofed the MAC of the gateway, that would act more like a DoS attack. That is because there would be a duplicate MAC on the network. The switch would always be updating its CAM table with the latest talker - sometimes that would be the spoof, and sometimes the true gateway. So the target station would sometimes get packets through to the true gateway and sometimes the MiTM. Also, the MiTM wouldn't be able to pass traffic to the true gateway since the switch would see the "gateway MAC" on the same port, so no need to forward it to the true port. All of that is true unless, the gateway had a secondary MAC that the attacker could take advantage of. Hope that makes sense and great question!

Thanks alot chris But i have a question: you specified the attacker ip in the filter but in real life scenarios i can't tell which one is my real gateway mac so what can we do here?

@ChrisGreer 2 жыл бұрын

There will be a MAC that several stations are ARPing for - that will be the gateway. They need that MAC address in order to communicate to another network. I would also watch for routing protocols from a MAC, that is another hint of the gateway. If you can capture in-line, then you can tell easily by the destination MAC for an off-net IP.

10/10 now how do you stop this kinda attack for me I had to get a new modem and router as well as factory rest every device that was on the network and thank god they are off but how do you stop this attack so you don’t have to reset everything ?

That‘s cool! Next, let‘s detect some common port scanning attempts and add those filters to our new Sec-Profile. P. S. Did you ever performed a nmap x-max scan on dec. 24th?

This would be bypassed by any adversary on the network that spoofs your GW's IP, no?

@ChrisGreer 2 жыл бұрын

Hello - thank you for the comment! Bypassed by an adversary? I would say that the adversary themself would be the one spoofing the MAC and forwarding the traffic between the target and GW.

Hello I used the filter and i got some packets but the MAC address is still the same as the original one. how can I find the actual fake MAC address after the capture as I am working with a preloaded pcap file.

@ChrisGreer 2 жыл бұрын

If the gateway MAC didn't change than you may be ok. I would look for the unsolicited ARPs coming from the attack box, then use the source MAC in the ARP field for the filter. If that doesn't catch anything spoofing the gateway IP, then the attack traffic was not captured. Hope that helps.
