Hacking Tools are computer programs and scripts that help hackers and security researchers find and exploit weaknesses in computer systems, web applications, servers and networks. There is a variety of such tools available on the market.
Some of them are open source while others are commercial solution. Some are dedicated for Windows users meanwhile another are only made for Linux lovers. In this article, we will discuss in brief the top 20 tools that are widely used to prevent hacking and getting unauthorized access to a computer or network system.
Nmap stands for Network Mapper. It is an open source tool that is used widely for network discovery and security auditing. Nmap was originally designed to scan large networks, but it can work equally well for single hosts. Network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
Nmap uses raw IP packets to determine
- What hosts are available on the network.
- What services those hosts are offering.
- What operating systems they are running on.
- What type of firewalls are in use, and other such characteristics.
Nmap runs on all major computer operating systems such as Windows, Mac OS X, and Linux.

4. ANGRY IP SCANNER
Angry IP Scanner is a lightweight, cross-platform IP address and port scanner. It can scan IP addresses in any range. It can be freely copied and used anywhere. In order to increase the scanning speed, it uses multithreaded approach, wherein a separate scanning thread is created for each scanned IP address.
Angry IP Scanner simply pings each IP address to check if it’s alive, and then, it resolves its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be saved to TXT, XML, CSV, or IP-Port list files. With help of plugins, Angry IP Scanner can gather any information about scanned IPs.

11. TOR BROWSER
Tor Browser is free and open-source software for enabling anonymous communication. The name is derived from an acronym for the original software project name "The Onion Router". Tor directs Internet traffic through a free, worldwide, volunteer overlay network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis.
- Tor Browser isolates each website you visit so third-party trackers and ads can't follow you. Any cookies automatically clear when you're done browsing. So will your browsing history.
- Tor Browser prevents someone watching your connection from knowing what websites you visit. All anyone monitoring your browsing habits can see is that you're using Tor.
- Tor Browser aims to make all users look the same making it difficult for you to be fingerprinted based on your browser and device information.
Using Tor Browser makes it more difficult to trace Internet activity to the user. This includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's intended use is to protect the personal privacy of its users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities unmonitored.

Kismet is a wireless network and device detector, sniffer, wardriving tool, and WIDS framework. Kismet works with Wi-Fi interfaces, Bluetooth interfaces, some SDR hardware like the RTLSDR, and other specialized capture hardware.
Furthermore Kismet works on Linux, OSX, and, to a degree, Windows 10 under the WSL framework. On Linux it works with most Wi-Fi cards, Bluetooth interfaces, and other hardware devices. On OSX it works with the built-in Wi-Fi interfaces, and on Windows 10 it will work with remote captures.
Some of the Features
- Kismet includes basic wireless IDS features such as detecting active wireless sniffing programs including NetStumbler, as well as a number of wireless network attacks.
- Kismet features the ability to log all sniffed packets and save them in a tcpdump/Wireshark or Airsnort compatible file format.
- Kismet also features the ability to detect default or "not configured" networks, probe requests, and determine what level of wireless encryption is used on a given access point.
- Kismet supports channel hopping. This means that it constantly changes from channel to channel non-sequentially, in a user-defined sequence with a default value that leaves big holes between channels (for example, 1-6-11-2-7-12-3-8-13-4-9-14-5-10).
- Kismet also supports logging of the geographical coordinates of the network if the input from a GPS receiver is additionally available.
Kismet differs from other wireless network detectors in working passively. Namely, without sending any loggable packets, Kismet it is able to detect the presence of both wireless access points and wireless clients, and to associate them with each other. It is also the most widely used and up to date open source wireless monitoring tool.
OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.
OpenSSL contains an open-source implementation of the SSL and TLS protocols. The core library, written in the C programming language, implements basic cryptographic functions and provides various utility functions. Wrappers allowing the use of the OpenSSL library in a variety of computer languages are available.
The OpenSSL Software Foundation (OSF) represents the OpenSSL project in most legal capacities including contributor license agreements, managing donations, and so on. OpenSSL Software Services (OSS) also represents the OpenSSL project, for Support Contracts.
Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS) created in 1998 by Martin Roesch, founder and former CTO of Sourcefire. Snort is now developed by Cisco.
Snort's open source network-based intrusion detection/prevention system (IDS/IPS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching.
The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans.
Snort can be configured in three main modes
- Packet logger.
- Network intrusion detection.
In sniffer mode, the program will read network packets and display them on the console. In packet logger mode, the program will log packets to the disk. In intrusion detection mode, the program will monitor network traffic and analyze it against a rule set defined by the user. Snort will then perform a specific action based on what has been identified.

Nessus scans cover a wide range of technologies including operating systems, network devices, hypervisors, databases, web servers, and critical infrastructure. The results of the scan can be reported in various formats, such as plain text, XML, HTML and LaTeX. The results can also be saved in a knowledge base for debugging. On UNIX, scanning can be automated through the use of a command-line client. There exist many different commercial, free and open source tools for both UNIX and Windows to manage individual or distributed Nessus scanners.
Vulnerabilities and exposures Nessus can scan for include
- Vulnerabilities that could allow unauthorized control or access to sensitive data on a system.
- Misconfiguration (e.g. open mail relay, missing patches, etc.).
- Default passwords, a few common passwords, and blank/absent passwords on some system accounts. Nessus can also call Hydra (an external tool) to launch a dictionary attack.
- Denials of service vulnerabilities
Nessus provides additional functionality beyond testing for known network vulnerabilities. For instance, it can use Windows credentials to examine patch levels on computers running the Windows operating system. Nessus can also support configuration and compliance audits, SCADA audits, and PCI compliance.
