Description
Originally released in 1996, Netcat is a netowrking program designed to read and write data across both Transmission Control Protocol
TCP and User Datagram Protocol (UDP) connections using the TCP/Internet Protocol (IP) protocol suite. Netcat is often referred to as
a "Swiss Army knife" utility, and for good reason. Just like the multi-function usefullness of the venerable Swiss Army pocket knife,
Netcat's functionality is helpful as both a standalone program and a backe-end tool in a wide range of applications. Some of the many
uses of Netcat include port scanning, transferring files, grabbing banners, port listening and redirection, and more nefariously, a backdoor.
This is the only book dedicated to comprehensive coverage of the tool's many features, and by the end of this book, you'll discover how
Netcat can be one of the most valuable tools in your arsenal.
* Get Up and Running with Netcat Simple yet powerful...Don't
let the trouble-free installation and the easy command line belie the fact that Netcat is indeed a potent and powerful program.
* Go PenTesting with Netcat Master Netcat's port scanning and service identification capabilities as well as obtaining
Web server application information. Test and verify outbound firewall rules and avoid detection by using antivirus software and the Window
Firewall. Also, create a backdoor using Netcat.
* Conduct Enumeration and Scanning with Netcat, Nmap, and More!
Netcat's not the only game in town...Learn the process of network of enumeration and scanning, and see how Netcat along with other tools
such as Nmap and Scanrand can be used to thoroughly identify all of the assets on your network.
* Banner Grabbing with Netcat
Banner grabbing is a simple yet highly effective method of gathering information about a remote target, and can be performed with relative
ease with the Netcat utility.
* Explore the Dark Side of Netcat See the various ways Netcat has been used to provide
malicious, unauthorized access to their targets. By walking through these methods used to set up backdoor access and circumvent protection
mechanisms through the use of Netcat, we can understand how malicious hackers obtain and maintain illegal access. Embrace the dark side
of Netcat, so that you may do good deeds later.
* Transfer Files Using Netcat The flexability and simple operation
allows Netcat to fill a niche when it comes to moving a file or files in a quick and easy fashion. Encryption is provided via several
different avenues including integrated support on some of the more modern Netcat variants, tunneling via third-party tools, or operating
system integrated IPsec policies.
* Troubleshoot Your Network with Netcat Examine remote systems using Netat's
scanning ability. Test open ports to see if they really are active and see what protocls are on those ports. Communicate with different
applications to determine what problems might exist, and gain insight into how to solve these problems.
* Sniff Traffic
within a System Use Netcat as a sniffer within a system to collect incoming and outgoing data. Set up Netcat to listen at ports
higher than 1023 (the well-known ports), so you can use Netcat even as a normal user.
