Get all the Passwords on LAN

Ok guys , herez a great tutorial of how to know the passwords on LAN ..... This trick is very efficient . You can know all the passwords on the lan using this . I have used it in my uni and I got all the passwords in the hostel . So must give it a try and if u have any problem then ask .

-=Step One=-

You want to activate "Sniffer" by activating the button next to the "Open" icon. You will also want to turn on APR which stands for APR Poison Routing. (Don't take POISON literally, It will not actually harm the computer you are piggybacking on)

-=Step Two=-

Switch your active/current tab to "Sniffer," after doing so right click in the middle of the blank fields and click on "Scan MAC Addresses" and make sure "All hosts in my subnet" is clicked with a dot in the circle. You should see several hosts pop up, if they did then you are doing everything correctly so far.

-=Step Three=-

At the bottom of Cain and Abel, you will see a tab called "APR," make that your active/current tab you are viewing under the "Sniffer" tab. Now click on the top white blank box in the "APR" subtab, and go up top and click on the "Add" button. Click on what ever you Routers IP is. Then click the IP of the target computer or whatever you want to piggyback on. Then press OK.

-=Step Four=-

After pressing OK you should see a line in the top box and it will either say IDLE or POISONING. If it says IDLE just give it a couple of seconds for it to start the poisoning. If it is POISONING go down to the bottom again and find "Passwords," make that your current/active subtab. Now passwords and usernames should be popping up under any of the select categories, mine are usually HTTP passwords but, yours might be different.




-=Ending=-

Thank you for reading my Cain and Abel sniffing tutorial, sooner or later I will write a follow-up guide on how to crack the passwords you get after completing all of the sniffing, but until then thanks again!

How to detect and block an ARP spoofing/poisoning attack on a LAN

ARP poisoning attacks are the most dangerous MITM attacks when working on a LAN. The most hazardous thing about this attack is that they go unnoticed for a very long time or in some cases they would never be detected if not checked for. No naive internet user is gonna check if he is being poisoned. This would go undetected in a trusted environment like an office or at college. Well then it is the responsibility of the admins to protect their clients from attack.



Detecting an ARP Spoofing attack
Well detecting an ARP attack is fairly easy assuming that the malware responds to standard ARP requests. Here's how you go about detecting a possible attack.

1. Start a network capture using a tool such as tcpdump or Wireshark.
2. Generate some traffic on your machine and then stop the capture.
3. Now analyze the traffic. You don't have to be an expert to do this. Check if you are getting ARP requests or responses from multiple addresses.

If you are getting ARP traffic from sources other than your default gateway there is possibly an eavesdropper. This eavesdropper could also modify what you recieve. A very good application of MITM is 'login credentials stealing', especially from SSL secured websites. Tools such as Ettercap and Cain & Abel can make this possible even for a script kiddie.

This was about detecting an MITM, but there is no manual way to block an MITM, other than bashing up the intruder sitting at the poisoning host machine.


Blocking an ARP Spoofing Attack:



ArpON (Arp handler inspectiON) is a portable handler daemon that make Arp secure in order to avoid Arp Spoofing/Poisoning & co.

This is possible using two kinds of anti Arp Poisoning techniques, the first is based on SARPI or "Static Arp Inspection", the second on DARPI or "Dynamic Arp Inspection" approach.

Keep in mind other common tools fighting ARP poisoning usually limit their activity only to point out the problem instead of blocking it, ArpON does it using SARPI and DARPI policies. Finally you can use ArpON to pentest some switched/hubbed LAN with/without DHCP protocol, in fact you can disable the daemon in order to use the tools to poison the ARP Cache.
