Network Hacking Tools and Tips

Network Hacking Tools and Tips

Tools Description:- 

1. Nmap

I think everyone has heard of this one, recently evolved into the 4.x series. Nmap (Network Mapper) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although  it works fine against single hosts. Nmap uses raw IP packets in novel ways to  determine what hosts are available on the network, what services (application  name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source.

Can be used by beginners (-sT) or by pros alike (packet_trace). A very versatile tool, once you fully understand the results.

2. Nessus Remote Security Scanner

Recently went closed source, but is still essentially free. Works with a client- server framework. Nessus is the worlds most popular vulnerability scanner used in over 75,000 organizations world-wide. Many of the worlds largest organizations are realizing significant cost savings by using Nessus to audit business-critical enterprise devices and applications.

3. John the Ripper

Yes, JTR 1.7 was recently released! John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different  architectures), DOS, Win32, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix flavors, supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.

4.Wireshark (Formely Ethereal)

Wireshark is a GTK+-based network protocol analyzer, or sniffer, that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and to give Wireshark features that are missing from closed-source sniffers. Works great on both Linux and Windows (with a GUI), easy to use and can reconstruct TCP/IP Streams! Will do a tutorial on Wireshark later
