Free Hacking Tools

Wondering which software is used for hacking? What is the best software for hacking a password? We have created a list of useful hacking tools and software that will help you do your job much easier.

Ethical hacking and online security involve a lot of efforts. Many tools are used to test and keep the software secure. The same tools can also be used by hackers for exploitation. Becoming a hacker is not easy it requires many skills. You can learn a few hacking tricks from free hacking tutorials online, some really cool hacking books, and books on information security . However, Along with all the skills, you need to have the best tools to perform hacking, security threat analysis, and penetration testing.

A hacking tool is a computer program or software which helps a hacker to hack a computer system or a computer program. The existence of hacking tools has made the lives of hackers much simpler when compared to the times they did not exist. But it does not mean that if the Hacker is equipped with a good hacking tool, his entire job is smoothly done. The hacker still requires the skills of all the aspects of hacking equally well.

This tools list includes the following types of hacking tools

  • Password Cracking Tools
  • Wireless / WIFI Hacking Softwares
  • Network Scanning Softwares
  • Packet crafting tools to exploit firewall weaknesses
  • Traffic Monitoring, Packet Sniffers, and Network Hacking Tools
  • Rootkit Detectors to Hack Filesystem
  • Vulnerability Search Tools: Fuzzers, Scanners and more

Password Cracker Software

A password cracker software, which is often referred to as a password recovery tool, can be used to crack or recover the password either by removing the original password, after bypassing the data encryption, or by an outright discovery of the password. In the process of password cracking, a very common methodology used to crack the user password is to repeatedly make guesses for the probable password and perhaps finally hitting on the correct one. It cannot be denied that whenever we are referring to cybersecurity, passwords are the most vulnerable security links. On the other hand, if the password is too completed, the user might forget it. Password Cracker software is often used by hackers to crack the password and access a system to manipulate it. Do not unethically use this software for hacking passwords.

In the next section, you would be getting familiar with some of the popular Password Cracker tools which are used by hackers for password cracking.


Hashcat is a password cracker for GPU(s) and CPU(s) using OpenCL. It can run on NVDIA and AMD devices. It is a very powerful password cracking tool that is also well documented.


It is a free password cracker software which is based on the effective implementation of the rainbow tables.

Encryption Tools

Times are changing and spying has become a common phenomenon everywhere. There have been increasing instances where even the governments have been found to be spying on their citizens from time to time. This is one of the prime reasons why the importance of Encryption has increased manifold. Encryption tools are very important because they keep the data safe by encrypting it so that even if someone accesses the data, they can’t get through the data unless they know how to decrypt the data. These tools use algorithm schemes to encode the data to prevent unauthorized access to encrypted data.

Some of the popular Encryption Tools will be discussed in this article:-


TrueCrypt is an open-source encryption tool that can encrypt a partition in the Windows environment (except Windows 8); it’s equipped for creating a virtual encrypted disk in a file. Moreover, it has the capability to encrypt the complete storage device. TrueCrypt can run on different operating systems like Linux, Microsoft Windows, and OSX. TrueCrypt stores the encryption keys in the RAM of the computer.
