Before we start, I need to stress that this video is for informational purposes only. If you know how these attacks work, then you can better defend against them. Do not try this on any system that you do not own or have permission to do so.
ARP, or Address Resolution Protocol, is used to discover MAC addresses and map them to an associated IP address.
The way this works is very simple. A host broadcasts a message to the entire network asking for the correct MAC address.
Computers are very trusting of the ARP messages they receive, and this can cause problems. If an evil attacker sends a specially crafted ARP message (gratuitous ARP) the attack can pretend to be someone they are not.
The good news is that these types of attacks are not as effective as they used to be. Most of the traffic we send is now encrypted so the bad guys will struggle to get anything useful.

[@mamaluigie195]

This is an extremely good tutorial. Very good graphics and satisfying demonstration of what an arp attack looks like.

[@MrSinaPRO]

Your explanation of the attack is very well presented and easy to understand! I'd be grateful if you could cover more attacks in your videos in the future!

[@Certbros]

Thanks! Great to hear you liked the video. You're in luck! I'll be posting another video like this shortly so look out for it 👍

[@bbgodzilla9697]

Not really quite uninformative actually

[@AminiMalik]

Really amazing explanation

[@alexandruilea915]

@@Certbros I've just looked up this video and you said that lucky 90% of the traffic is encrypted which is correct but in the security world the weakest link in the chain is the one that will break it up. And that weak link is usually the people using the same password on every (or multiple) websites. Not sure how you choose your real life target based on their IP address, but if you go at a restaurant and hijack the router you just have to wait for the target to log into the first website that's not protected or even trick people into registering on a random website that promises to get them some free stuff that they are interested into.

[@TheRohel]

I am studying my foundational Cyber security course at college and I have a strong CCNA level networking background. I got amazed with the display of tools that Kali can offer and the simplicity of the use! Nice explanation of the theory and good demonstration of the technical side.

[@Maanuu000]

Your videos are AMAZING! Both theory and real demonstration in all of them. Thanks man!

[@shyayetgani-ikilama500]

[@crash938]

Does the above also work as shown when the MAC address has been spoofed? If an attacker wanted an extra layer of concealment. Also, ARP Poisoning MITM with a force disconnect kind of attack to intercept TLS key generation communications and create the new key at the same time as the target system?

[@DEBORAHJOSEPH-vj4pb]

Hi sir may I know what network setting you use in the virtualbox? Is it NAT or bridged adapter?

[@James_Knott]

ARP is not used with IPv6. It uses Neighbor Solicitation ICMPv6 multicasts. Also, ARP predates IPv4. It was in use with other protocols before IPv4 became popular.

[@krzysiek1918]

One word: Wow.

[@yassinom2466]

thanks

[@chris_tina.ja_c5193]

I have been a victim of that many times. Every time i get a computer i have it some days, and its been tanken over also mobile Phone. I Hope they make it more secure.

[@michaelbrink9996]

Hi CertBros. How would you run ettercap externally ie sitting outside of the network attacking devices inside a network without having a kali machine running on the inside of the network?

[@davidl3832]

nice video

[@nathaniel9184]

Thanks.

[@forestcat512]

Some Questions i have after seeing this Video. So you can check if youre getting intercepted but can you change the arp cache manually back to the routers mac adress to prevent the traffic going through the attackers pc? And it should be possible to lead the traffic of the victim into nothing so the victim has no Internet right?

[@raphaelramos4016]

therein lies the importance of perceiving the MAC address instead just IP: the latter is not enough to completly identify a host.

[@chochanga]

Hi cert! When is the full ccna course coming?

[@Certbros]

Still working on the full course. You can pre-purchase here if you want it before: certbros.teachable.com/p/cisco-ccna/?product_id=2833094&coupon_code=PRELAUNCH21

[@manfredschultz9619]

Can that Host Scan spot a device from a different router LAN-to-WAN’ed to the secondary router? Said device’s set on “private” (not included in RIP, Static Routed AND also with a subnet mask of 255.255.255.255

[@carakintz3536]

Separate quizzes for check on learning would be welcome❤

[@Fernandez218]

seems like an easy way to detect MITM attack for LAN is to do 'arp -a' and then compare it with the MAC address written on the router, since the written one is impossible for a hacker alter. I had a question: are MITM attacks possible on a home network? The hacker must be connected to what looks like a switch? Seems like this is a feasible strategy on public wifi but outside of a home LAN is not possible? Thanks, in advance.

[@rickg672]

Excellent Tut but can you get away with this hack on a switched network as opposed to a network where the central connection point is a hub?.

[@elprquex]

try SSL Stripping. if steel working. or give me feed back

[@ratatui900]

at the end you've said that https saves you from this kind of attack but how so if attacker can still enercept key exchange of ssl handshake? attacker won't be able to alter user's request or servers's response, but surly can read it right?

[@RealmOfZomJ]

thanks :)

[@RealmOfZomJ]

such a good comment

[@wajidnezam246]

awesum

[@ayesharehman1995]

Hi CertBros, I got lucky to stumble upon this video and it helped me great deal thanks to you. Following you r video I was able to get the traffic to my machine but could you please now guide me how to modify the packets that now i am recieving before i send them back to the server/victim machine? I have been looking for this for a long time for my semester project I need to do this but i Am helpless. would be greatful if you could help me in any way. Thanks.

[@adityaraut9364]

Great tutorial but how to check the default gateway in linux?

[@mihaicostin824]

Hey! I loved the video, though I seem to have a problem: all the arp replies from the attack appear in wireshark on my virtual machine, but not on the victim machine. Does anyone have any idea what could cause this?

[@kilianschnitzer1791]

Does ARP Poisining only work in your local network? If yes - could you ARP Poison e.g. your router which is in another city / house using their GW IP?

[@yangliu4192]

I have a little question that once the arp table is changed, the message is going through router or switch. I am lost

[@rickykeim2005]

Hi I started getting notices from my Firewall that these attacks were being blocked and I can't seem to connect to the internet on my computer. Can my ISP help me with this problem? I don't know what to do about this.

[@battuhant]

when ı do this, my host machine's mac address that kali built on appears on the other device on the same lan instead of my kali's mac address, why?

[@user-ok3in2dc9c]

I am wondering if anyone could tell me why the default gateway for the virtual machine is different than the default gateway for the host. Both are on the same wifi and when I scan the default gateway from either host or VM, the scans are the same so I'm assuming the hardware is the same but I can't figure out why both have different IP's and DG's.

[@yuvrajsethi6299]

Hi there Watched you video and its amazing But I have a problem.. In Ettercap, the host lists i am getting is random hosts made by machine as I can guess from there ip address and Mac address. Why is this happening?

[@ip9153]

Can I practice this in my home network for educational purposes?

[@anntakamaki1960]

Even if data is encrypted, can the hacker redirect you to a malicious website?

[@mcpulya6890710]

the credentials spoofing will be available only on http sites or on https as well?

[@haydarveli6470]

Can't the attacker de-crypt TLS handshake data? I was asking this to myself. TLS is end to end encryption not hob by hob (or node to node) security. So an attacker who resides in MITM position will not be able to de-crypt data. However if this attack would be launched in a local area network. Than this time would layer2 and layer 3 security protocols (MACsec and IP sec) destroy the attack or not, i couldn't be sure. How did i come here from PTP networks i don't know that either :) But in any case thanks for the explanation.

[@PinkdoomXD]

But mitm is dangerous itself? Like I was searching for solutions for my problem (did not found) and found this video, like i installed mitm so i could have the grasscutter private server to make tiktok vids, and now my internet isnt working, tho have anyway to deactivate the proxy?

[@gracechee3287]

Hi is that possible to recover back the pc default gateway MAC address?

[@plang2008]

hi, in this example how much machine have you ? 3 ?
