RainbowCrack
Rainbow Crack as the name suggests, is a cracker for hashes with the Rainbow Tables. It runs on multiple operating systems such as Linux, Windows Vista, Windows XP (Windows Operating Systems). It supports both Graphical User Interface as well as Command line Interface. It's software which is used for password cracking by generating rainbow tables, fuzzing all the parameters.

Kali Linux

This is a creation of the makers of BackTrack. This is regarded as the most versatile and advanced penetration testing distribution ever created. The documentation of the software is built in an easy format to make it the most user friendly. It is one of the must-have tools for ethical hackers that is making a buzz in the market.

Brutus

Brutus is one of the most flexible and free password crackers which operates remotely. It is popular also because of its high speed and operates under operating systems such as Windows 2000, Windows NT and Windows 9x. Currently it does not operate under the UNIX operating system. Brutus was initially designed to check network devices like routers for common as well as default passwords.


Aircrack

Wi-Fi Crack allows you to crack any wireless network with WEP security. Powered by AirCrack-NG, the popular, cross-platform, wireless security cracking command-line tool, Wi-Fi Crack you a takes you step-by-step through process of cracking the security of a WEP-based wireless network using a beautiful OS X graphical user interface. After selecting the specified wireless interface and network, Wi-Fi Crack launches powerful command-line tools to capture wireless packets and obtain the WEP password. If you encounter errors launching AirCrack-NG, then install it using MacPorts.

It is a network software suite used in 802.11 Wireless Local Area Networks. It consists of tools such as a packet sniffer, detector and a WEP. This tool runs on both Windows and Linux Operating systems. It can work with any type of wireless network interface controller, provided the driver is supporting the raw monitoring mode.



Wifislax

Wifislax is an open source Linux operating system based and inspired by the Slackware Linux distribution. It’s main goal is to support the latest Wi-Fi technologies. The system provides out-of-the-box support for a wide range of wireless and wired network cards. In addition, it contains a large number of security and forensics tools, which transforms it into a pentesting (penetration testing) distro.

John The Ripper

John the Ripper is a free software for password cracking which was originally designed for the Unix Operating System. At present, it can run on 15 Operating systems which includes 11 different versions of UNIX, Win32, DOS and BeOS. It has the capability to combine several password crackers into a single package which has made it one of the most popular cracking tools for hackers.
The objective of this security tool is to locate the valid user identities in a Virtual Public Network along with the secret key combinations. Once this is accomplished, this information can be used easily by a hacker to have access to a VPN in an unauthorized manner

Wireshark

If you want to put a security system, Wireshark is the must have security tool. It monitors every single byte of the data that is transferred via the network system. If you are a network administrator or penetration tester this tool is a must have.

Netfilter

Netfilter

                                     

Netfilter offers softwares for the packet filtering framework that works within the Linux 2.4.x and later series of kernel. The softwares of Netfilter help in packet mangling including packet filtering along with network address and port translation., it is very simple to capture that traffic and later analyze that from any machine over LAN (and even Internet). That bring us to this website password hacking guide that works on any site that is using HTTP protocol for authentication. Well, to do it over Internet, you need to be able to sit on a Gateway or central HUB (BGP routers would do – if you go access and the traffic is routed via that).


PF: OpenBSD Packet Filter

It is an OpenBSD system that enables filtering of TCP/IP traffic and also performs Network Address Translation. It also helps in conditioning and normalizing of TCP/IP traffic along with packet prioritization and bandwidth control.

Fuzzers To Search Vulnerabilities

Fuzzing is a term used by hackers for searching a computer system’s security vulnerabilities. Here is a list of a few:


Dig

It is a complete searching and indexing system that is used for a domain or internet. It works in both Linux and Windows system. It however does not replace the internet-wide search systems like Google, Infoseek, AltaVista and Lycos.


CURL
It is a free and open source software command-line tool that transfers data with URL syntax. It supports HTTP/HTTPS, Gopher, FTPS, LDAP, POP3 and many others. It can run under a wide variety of operating systems. The recent stable version is v7.37.1.

Backtrack 5r3

This operating system is built keeping the most savvy security personnel in mind as audience. This is also a useful tool even for the early newcomers in the information security field. It offers quick and easy way to find and also update the largest database available for the security tools collection till date.

He advantage of BackTrack 5 (BT5) is that it offers a slew of security and forensic tools on a live DVD, ready to use. It’s based on Ubuntu Lucid (10.04 LTS) with Linux kernel 2.6.38 and some patched WiFi drivers to allow injection attacks. You can download the distribution in a GNOME or a KDE version, for 32-bit or 64-bit x86 machines. It’s a live DVD ISO file, which you can burn to a DVD or write to a USB stick. On the desktop of the live session, there’s an installer icon if you want to install BackTrack permanently. For the first time, the project also has an image for ARM, which you can run on your smartphone or tablet to test the security of a wireless network.
