Introduction

TCPView is a Windows program that will show you detailed listings of allTCP and UDP endpoints on your system, including the local and remoteaddresses and state of TCP connections. On Windows Server 2008, Vista,and XP, TCPView also reports the name of the process that owns theendpoint. Profexam player dmg cracked for mac. TCPView provides a more informative and conveniently presentedsubset of the Netstat program that ships with Windows. The TCPViewdownload includes Tcpvcon, a command-line version with the samefunctionality.

Using TCPView

When you start TCPView it will enumerate all active TCP and UDPendpoints, resolving all IP addresses to their domain name versions. Youcan use a toolbar button or menu item to toggle the display of resolvednames. On Windows XP systems, TCPView shows the name of the process thatowns each endpoint.

By default, TCPView updates every second, but you can use theOptions|Refresh Rate menu item to change the rate. Teamviewer ctrl alt del. Endpoints thatchange state from one update to the next are highlighted in yellow;those that are deleted are shown in red, and new endpoints are shown ingreen.

You can close established TCP/IP connections (those labeled with a stateof ESTABLISHED) by selecting File|Close Connections, or byright-clicking on a connection and choosing Close Connections fromthe resulting context menu.

You can save TCPView's output window to a file using the Save menuitem.

Using Tcpvcon

Tcpvcon usage is similar to that of the built-in Windows netstatutility:

Usage: tcpvcon [-a] [-c] [-n] [process name or PID]

ParameterDescription
-aShow all endpoints (default is to show established TCP connections).
-cPrint output as CSV.
-nDon't resolve addresses.

TCP/IP Hijacking is when an authorized user gains access to a genuine network connection of another user. It is done in order to bypass the password authentication which is normally the start of a session.

In theory, a TCP/IP connection is established as shown below −

To hijack this connection, there are two possibilities −

  • Find the seq which is a number that increases by 1, but there is no chance to predict it.

  • The second possibility is to use the Man-in-the-Middle attack which, in simple words, is a type of network sniffing. For sniffing, we use tools like Wireshark or Ethercap.

Example

An attacker monitors the data transmission over a network and discovers the IP's of two devices that participate in a connection.

When the hacker discovers the IP of one of the users, he can put down the connection of the other user by DoS attack and then resume communication by spoofing the IP of the disconnected user.

Shijack

In practice, one of the best TCP/IP hijack tools is Shijack. It is developed using Python language and you can download it from the following link − https://packetstormsecurity.com/sniffers/shijack.tgz

That time i got reincarnated as a slime dub online. Here is an example of a Shijack command −

Here, we are trying to hijack a Telnet connection between the two hosts.

Hunt

Hunt is another popular tool that you can use to hijack a TCP/IP connection. It can be downloaded from − https://packetstormsecurity.com/sniffers/hunt/

Quick Tip

All unencrypted sessions are vulnerable to TCP/IP session hijacking, so you should be using encrypted protocols as much as possible. Or, you should use double authentication techniques to keep the session secured.
