Man In The Middle Attack | Blocking Routes On Victim's PC

This is a commonly used method used on networks to cut down the network connection of victim. It makes  a Denial of Service attack on the Victim so that he doesn’t get internet access. It does so by flooding the switch with unreal MAC address entries that point to the victim’s ip address, so the packets are mapped incorrectly and the victim receives no packets. 

Lets understand how it works:
Suppose there is a Desktop PC with:

      Hostname :  C4  
      IP : 10.0.0.81 
      Gateway : 10.0.0.138
We use here 3 tools:
1. Attacking/Blocking
2.Ethereal : To Checks Packets.
3.AntiArp : To monitors and block all incoming and outgoing ARP traffic from / to my pc.
  
First we BLOCK user with LAN IP 10.0.0.10  


On the ethereal, it made 1767 ARP packets in only one minute..!


The AntiArp shows that I ‘m sending fake Mac address to the gateway and I’m disguised as the victim’s IPaddress. (while if we make a man in the middle attack , we can get victims MAC address and set is as our MAC addr and give victim other addr ) .




How to defend against a similar type of attack ?
. AntiArp is a nice tool the defends the MAC Denial of Service attack.

How To Increase Internet Broadband Speed (Settings in windows)


Many members asked for a tutorial on how to get more bandwidth I'll write one up quickly. Sorry friends it doesn't involve stealing bandwidth though...LOL. Now this isn't going to make your speed double or triple or anything crazy so if you are on a 3 Mb line don't expect 12 Mb when you're done. 


Now with that said as far as the 128 Mb in my sig. goes that was recorded last November and I still don't know how I pulled that. I am thinking they must of been doing some work on the line at the time because I haven't gotten close to that in months.


I'm paying for a 16 Mb line but pull a steady 20 Mb to 28 Mb download all day long with it peaking at about 40+ Mb depending on the time of day. 


Before we begin head over to



or

and run 3 speedtests on a server close to you. That will give you a good indication of what you are actually getting download wise. 


Lets start by changing out your DNS. Your DNS is what controls how domains are converted to i.p.'s for your computer to connect to. Get a slow one and you will have trouble loading pages and so forth. Get a fast one and you will increase your speed.


I recommend downloading and running:

It will run some 200 DNS for you and get accurate connect times for them based on your location. I could give you the DNS that I run....but I may be closer to that DNS then you and get a better connect then you. Its best to run the program and let it select the fastest for you and your area.


It hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. namebench is completely free and does not modify your system in any way. This project began as a 20% project at Google.
namebench runs on Mac OS X, Windows, and UNIX


Now you need to put those fast DNS to work for you. I can only tell you how to change your DNS in XP and Win7 : In XP go to 'settings', 'control panel', 'network connections' and then right click on the active internet connection (the one you use to connect to the internet). Scroll down to and select 'properties'. Next scroll down and highlight 'Internet Protocol (TCP/IP)' and select properties. At the bottom where it says 'use the following DNS server addresses' is where you put your new DNS.

In Win7 Left Click on network icon taskbar>choose  Open network and sharing center>click on your active connection>choose Properties>Next scroll down and highlight 'Internet Protocol (TCP/IP)' and select properties>Enter your Preferred and Ulternative DNS 

or

Dns jumper v1.0.4

This  utility will need Administrative privileges to change the DNS, so if you are on XP you must be  logged in to an Administrator account, and if you are on Vista or Windows 7 you will have to provide the administrator login details if you not logged in as an admin.
click the below link to download the Dns jumber


Next lets run one more program:

Most computers when they ship out of the box are not tweaked for a fast connection. They come with standard settings that will get you on the 'net and that is all. We need to tweak the registry settings in our computer such as MTU, RWIN, and even advanced ones like QoS and ToS/Diffserv prioritization. Once you run the program slide the dial to what you are supposed to be getting bandwidth wise. Don't go crazy with it and slide it all the way to 100+ if that is not what you are supposed be getting as it won't do any good. Once you have the dial slid to where you want it click on 'optimal' at the bottom and then 'apply changes'. You will see a window pop up and it will list all the changes it makes to your registry files by showing your 'old value' and 'new value'. You can hit 'OK' to select the changes. On the bottom left is a 'backup' box with a check mark. Leave it checkmarked as it will back up your settings just in case something goes wrong....here is a hint though I have ran this on all the computers in the house XP and Vista and had no problems with it.


Now head back over to

or

and run 3 speedtests again on a sever near you and see if you have squeezed some bandwidth out of that greedy ISP. You should notice a difference...

How to access the secret Internet AKA The Deep Web


What is the deep web? 

The deep web is that part of the internet that is not accessible through regular searches on google or on other search engines. 

Here are some facts about the deep web...
  1. The size of the public information on the deep web is 400-500 times larger than the information on the surface web.
  2. The deep web has 7500 TB(terabytes) of information while the surface web has 19 TB of information.
  3. The deep web has 500 billion of documents compared to the 1 billion on the surface web.
  4. The HQ content on the deep web is up to 200 times greater than the HQ content on the surface web.
  5. Almost 95% of the deep web can be accessed without registering/ having a subscription.


Who usually accesses the deep web?

Beneath the surface web there are hackers, scientists, drug dealers, assassins, kidnappers, perverts, police, feds, physicists, sociologists ets.

A good reference point on the deep web is the hidden wiki. 

What is the hidden wiki?

The hidden wiki is like wikipedia. It is part of the ".onion" network and it can be accessible only through the TOR network. 


What is the TOR network?

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis

Can i access the hidden wiki?
The answer is yes, you can access it only through TOR.
A picture of the hidden wiki can be found here: http://i.imgur.com/Xq7ih.png


How do i connect to the deep web? 

To connect to the deep web you will need to have Tor.
You can download Tor Bundle from this link: https://www.torproject.org/

Tor bundle is a version of Firefox that is pre-cofigured with TOR button. It is configured to not keep cookies and javascript is disabled for enhancing the security.
