ARP spoofing Puns

Hello,

I am working for a cloud service provider. Currently, each Costumer Edge is connected to its Provider Edges (Juniper MX204) in a different private IP network.

Although it would make Provider Edges configuration easier if we put all Costumer Edges in the same IP network, it would also greatly increase the possibility of Man In The Middle attack with ARP spoofing if my understanding is correct. F.I., we fully manage the Costumer Edges.

L2-wise, we've got Arista and Cisco appliances.

Is it better to stay with the old design or is there a way to deal with ARP spoofing?

Thanks in advance

- A simple script I made (My 1st project) that implements ARP spoofing. Hope you guys like it!

Hi! I am currently working developing a CTF for a cybersecurity club I am in. I have recently been interested in developing my own CTF around ARP poisoning. I want to make it an attack-defense style one so I’ve been trying to find information about what happens when two actors try to basically ARP spoof each other and this kind of network interaction.

Just for background I plan to make it so that you are trying to sniff usernames and passwords and you get points for your control of an account. To get a point you have to login and vote for yourself and you can do that at timed intervals. (So that they have to login creating a vulnerability for the enemy to exploit). Also won’t be encrypted since I’m trying to make this CTF on the easier side.

The questions:

1. Can I implement ARP spoofing in this way for a CTF?
2. How does ARP spoofing work on a network with multiple actors trying to sniff each other?
3. I saw something about Linux ignoring unsolicited requests on the Wikipedia page. Does that mean I can’t make it work if all the users are on Linux or do distros matter?
4. I know about general tools to do ARP spoofing like Ettercap, but I am looking for a more granular tool that gives a user more control so that they can understand ARP more and allow for interesting strategies to develop from it with a simple understanding. What are some tools or how would I set up such a thing?

My Ring Chime was refusing to connect to WiFi, but pretty every other device on the network was fine.

It turned out my modem was both ARP spoofing as well as changing it's MAC address, and escaped the MAC-based vlan I had originally gated it behind.

The full story as well as the tools I used to find it (Wireshark did most of the work) is here if you are interested it read more:

Long story short Im researching a bit on intercepting packets from the connection of a Yeelight (Smartbulb) to a WLAN.

So the way you set up the smartbulb to a WLAN is via an open WiFi network that the bulb itself opens. Then the phone connects to such WiFi hotspot via the app to send the information of the WLAN to the bulb for it to connect to. I have sniffed the packets via monitor mode and I have a pretty good idea on how the phone commands the smartbulb to connect. Now I would like to inject packets during such connection.The only problem is that when I connect to the bulb's network (before it is connected to the WLAN) with my laptop I can not ping let alone ARP Spoof the phone, so I could potentially intercept the packets and connect the bulb to another network while the app thinks that is being connected to the real network. Is there any other way I could potentially reach such mitm situation without ARP Spoofing

That's it. Everything's on the title. I already know about Netcut but are there more? (sorry for the bad english)

Hi, i'm making a project on the Detection/Prevention Of Cyber Attacks- ARP/IP Spoofing and i'm required by my supervisor to develop algorithms using Machine Learning Models/Techniques with the implementation on R Studio. However, I dont know where to look for the datasets that would apply for this, I would use to create the ML models would have to be used from Wireshark or where do I I've done research regarding datasets that I could use for this but haven't been able to find anything relating to specifically my topic. Anyone able to help?

I've only started learning about Cyber Security recently and expected to do quite a lot of work towards this project as its very important. Would extremely appreciate some guidance.

With packet injection too.

Hello there!

I am trying to conduct an ARP spoofing attack on my system. When I start sniffing the packets using arpspoof tool, the internet connection in the victim system stops. So in a sense, my arp attack is like a wall instead of a bridge, lol. Any way to fix this?

I've edited the /proc/sys/net/ipv4/ip_forward , set on 1, but didn't change anything. What else should I do to allow packet forwarding?

Hello Guys , I Am New To MITM Attacks. So , I Started With ARP Spoofing..

Host Computer : Kali LInux #192.168.43.29

Targeted Computer : Windows 7 #192.168.43.75

Router IP : 192.168.43.238

Commands I Used In Kali Is..

bettercap -iface wlan0
192.168.43.0/24 > 192.168.43.29  » net.probe on
192.168.43.0/24 > 192.168.43.29  » set arp.spoof.fullduplex true
192.168.43.0/24 > 192.168.43.29  » set arp.targets 192.168.43.75
192.168.43.0/24 > 192.168.43.29  » arp.spoof on
192.168.43.0/24 > 192.168.43.29  » set net.sniff.local true
192.168.43.0/24 > 192.168.43.29  » net.sniff on
192.168.43.0/24 > 192.168.43.29  » hstshijack/hstshijack

I Didn't Get Any Error While Executing All The Above Commands .

But When I Login Into Stackoverflow on windows 7 , I Didn't Get Any Post-Requests On Bettercap.

But When I Login into http://testphp.vulnweb.com/login.php , I got The Login Details In Bettercap.

Can Any Tell Me How To Bypass MITM IN HTTPS & HSTS Websites??

Thanks In Advance :-)

Hey Guys,

Some outsider is in my router. I could see Arp attacks using XArp. I tried changing the Mac address using ARP -a but XArp showed 'StaticPreserveFilter'... Which changed the Mac address to attacker supplied. Any way to throw him out? I tried using VPN but still ARP spoofing was detected for my IP. I just have a basic router.

Thanks

I'm targeting just one host and I don't use a VM.

I've used arpsoof and urlsnarf:

#Intercept packages from victim

arpspoof -i [Network Interface Name] -t [Victim IP] [Router IP]

#Intercept packets from router

arpspoof -i [Network Interface Name] -t [Router IP] [Victim IP]

urlsnarf -i [Network interface name]

I have been recently getting into hacking and one of the recent ones I tried was the MITM attack using the ettercap arp poisoning feature, I followed the steps including the port forwarding but when I execute the attack it works as a DOS and stops the victim's internet connection rather than letting me intercept the traffic. The target was an Android phone and I'm using Kali in a VMware environment. Does anyone have any insight on why this may happen? TIA

Hi. This has been in my head for the past month and bloodied out looking for a solution that works.

We have an attendance system that we access over the web and about 6 weeks ago, the site was redirecting to a random IP which we didn't own and knew of

The rogue IP was showing JSON output {"code":"ResourceNotFound","message":"/ does not exist"} and nothing harmful obvious... my manager has been on the case since. Recently, found this application called Ettercap and used it as an exploit tool and I was able to achieve the same result with trying to redirect a domain to another IP

We believe that the "attack" originated from the inside and sort of used a tool similar to Ettercap... which I now need to counter-measure to avoid future occurrences

We use HP switches (1910s, 2530s) that have ARP anti-attack and Dynamic ARP attack - we don't see them do enough to prevent such attacks as it still happens when we are testing

I am now looking on host-based tools such as arpon which I am working on the setup (not quite sure if I got it right but DNS spoofing still happens) and looking further...

What else should I look into? We don't have an IPS/IDS appliance on the network, we use routers from a Latvian company called Mikrotik and configure them to act as firewalls.

This project is making its way around the internets and I thought I would give it a try to see if the devices on my home network are behaving.

It appears my eero gen 2 is blocking the ARP spoofing they are using to conduct this inspection. I've read some old articles with similar situations regarding Disney's Circle, but I've hardwired my Mac to the eero and still no dice.

Has anyone else tried this yet?

I have been successful so far in doing apr spoofing on my target machine using bettercap.However when i run the net.sniff command.It shows me the packets for all the endpoints on the network and not just the target machine.It becomes really tedious to filter dns requests from one particular machine.

Also, how do you guys log the output of the net.sniff output to a file ?

hello guys

i have problem

so i have a public wifi (i run a cafe) there is some clients using apps like wifikill and netcut to kill the connection , i don't know what do how to stop it

i have tried some security apps and softwares to defend this arp spoofing it worked but its not a solution just a temporary

i just want to protect arp spoofing from the router , so can i ? and how ?

thank you

When you spoof MAC address then in case if you send something from your device then in case if the target replies to the spoofed address then it would go to the attracter's machine who spoofed the message or would it go to the device with the actual machine having that MAC?

I do know that if IP is spoofed then in case the target replies, the message will not go to the attacker's machine instead it will go to the actual machine with the real IP address which was spoofed by the attacker. Am I right?

If so then, does this happen with ARP spoofing as well?
If yes, then in MITM after the attacker spoofs the MAC address then he/she shouldn't be able to get the reply back from the target machine as it gives the reply message to the actual machine right?

It would be very helpful if anyone can remove this confusion off my head. I really confused here!

Howdy folks,

I've been researching ARP spoofing/poisoning ( whichever you want to call it ) and I've got myself a small bit versed in how to conduct the attack and mitigate it, however i get the feeling this attack is somewhat rudimentary and would not be common or have a high success rate today when launched against a large enterprise with sufficient network security monitoring.

I may be wrong as i often am, can anyone provide an answer? If it is common which environments do you see it being most prevalent in eg small offices etc

Any advice is appreciated, Thank you

Hi fellow jailbreakers ! Is there a tweak that defends and/or detects ARP spoofing attacks ? (iOS 12)

Hey everyone. Is your organization’s network protected against MITM ARP spoofing/sniffing? If so, what are you using?

Does using a static arp table on a machine actually offer protection against arp poisoning? I don't see why an attacker couldn't just also spoof their MAC.

If the attacker is on the network, it can just listen for who is talking to who. Then look at the target's MAC, match it, then start it's attack.. right?

I feel like i must be missing something because i've had several people imply that a static arp table offers some sort of grand protection. I've google'd a bit, but it just seems to be reinforcing what I thought.. which makes me think i'm definitely missing something :/

I've got a rather dumb IoT device that will occasionally "lose" its config and change its IP to its factory default. Unfortunately, this is also my router's IP on this VLAN. The config loss lasts a few minutes. The device somehow gets the memo and restores its working config with the correct IP it originally got from DHCP.

This is resulting in some network blips and seems to be a pretty textbook ARP spoofing attack; except, it's from a legitimate host that's just being ... dumb. Short of putting a device in front of the misbehaving one to filter its bad ARPs, I'm looking at my switches to take care of the problem with DAI or something similar.

Here's how the network looks: Dumb IoT -> WiFi (UniFI WAP) -> Cisco SG300 #2 -> Cisco SG300 #1 -> Router

I've tried playing with DAI on the second SG300, but I think without a full DHCP environment - it's fairly worthless? I tried applying a static ARP inspection list, but it looks like if I do that - I have to list all my static addresses that I use? The docs for ARP inspection and Source Guard on the SG300 aren't great. So any help is appreciated!

Hopefully that all made sense. Thanks for reading!

EDIT: Minor wrinkle. If I mark the WiFi interface on the second SG300 as trusted for DHCP snooping (in order for DHCP to actually work on WiFi), I also seem to have to mark it trusted for DAI as well? I think that negates the point and tries to push the issue further down to the AP's job.

EDIT 2: Scratch that first edit. This OS is funky. If I go back and re-mark the AP's interface as trusted for DHCP snooping it sticks and remains without DAI trust. I am worried though that I may have to get a real Cisco to do an actual ARP access-list or something similar for this, especially since this switch is fanless and preferably needs to stay that way. (Fanless Ciscos are depressingly not cheap.)
