List of Tools

Below is a list of tools that come pre-installed for ethical hacking using Kali Linux. This list is by no means expansive as Kali has a plethora of tools, all of which cannot be listed and explained in one article.

Aircrack-ng

Aircrack-ng is a suite of tools used to assess WiFi network security. It focuses on key areas of WiFi security:

  • Monitoring: Packet capture and export of data to text files for further processing by third-party tools.
  • Attacking: Replay attacks, de-authentication, fake access points, and others via packet injection.
  • Testing: Checking WiFi cards and driver capabilities (capture and injection).
  • Cracking: WEP and WPA PSK (WPA 1 and 2).

All tools are command line which allows for heavy scripting. A lot of GUIs have taken advantage of this feature. It works primarily Linux but also Windows, OS X, FreeBSD, OpenBSD, NetBSD, as well as Solaris.

Nmap

Network Mapper, also commonly known as Nmap, is a free and open source utility for network discovery and security auditing. Nmap uses raw IP packets in stealthy ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

Many systems and network administrators also find it useful for tasks like:

  • network inventory
  • managing service upgrade schedules
  • monitoring host or service uptime

THC Hydra

When you need to brute force crack a remote authentication service, Hydra is often the tool of choice. It can perform rapid dictionary attacks against more than 50 protocols, including telnet, FTP, HTTP, HTTPs, SMB, several databases, and much more. it can be used to crack into web scanners, wireless networks, packet crafters, etc.

Nessus

Nessus is a remote scanning tool that you can use to check computers for security vulnerabilities. It does not actively block any vulnerabilities that your computers have but it will be able to sniff them out by quickly running 1200+ vulnerability checks and throwing alerts when any security patches need to be made.

WireShark

WireShark is an open-source packet analyzer that you can use free of charge. With it, you can see the activities on a network from a microscopic level coupled with pcap file access, customizable reports, advanced triggers, alerts, etc. It is reportedly the world’s most widely-used network protocol analyzer for Linux.
