kali Linux Top 10 Tool .

1. Hydra

Hydra is a parallelied network logon cracker. Hydra works by using different approaches of generating possible passwords, such as wordlist attacks, brute-force attacks and others. Hydra is commonly used by penetration testers together with a program named crunch, which is used to generate wordlists. Hydra is then used to test the attacks using the wordlists that crunch created.

Hydra is set to be updated over time as more services become supported. The creator of Hydra publishes his work in repositories like GitHub.

Supported Protocols

Hydra supports many common login protocols like forms on websites, FTP, SMB, POP3, IMAP, MySQL, VNC, SSH and others

2. Metasploit Framework

The Metasploit Project is a computer security project that provides information about security vulnerabilities and aids in penetration testing and IDS signature development. It is owned by Boston, Massachusetts-based security company Rapid7.

Its best-known sub-project is the open-source Metasploit Framework, a tool for developing and executing exploit code against a remote target machine. Other important sub-projects include the Opcode Database, shellcode archive and related research.

The Metasploit Project includes anti-forensic and evasion tools, some of which are built into the Metasploit Framework. Metasploit is pre-installed in the Kali Linux operating system.

The basic steps for exploiting a system using the Framework include:

  1. Choosing and configuring an exploit (code that enters a target system by taking advantage of one of its bugs; about 900 different exploits for Windows, Unix/Linux and Mac OS X systems are included);
  2. Optionally checking whether the intended target system is susceptible to the chosen exploit;
  3. Choosing and configuring a payload (code that will be executed on the target system upon successful entry; for instance, a remote shell or a VNC server);
  4. Choosing the encoding technique so that hexadecimal opcodes known as “bad characters” are removed from the payload, these characters will cause the exploit to fail.
  5. Executing the exploit.

This modular approach – allowing the combination of any exploit with any payload – is the major advantage of the Framework. It facilitates the tasks of attackers, exploit writers and payload writers.

Metasploit runs on Unix (including Linux and Mac OS X) and on Windows. The Metasploit Framework can be extended to use add-ons in multiple languages.

To choose an exploit and payload, some information about the target system is needed, such as operating system version and installed network services. This information can be gleaned with port scanning and OS fingerprinting tools such as Nmap. Vulnerability scanners such as Nexpose, Nessus, and OpenVAS can detect target system vulnerabilities. Metasploit can import vulnerability scanner data and compare the identified vulnerabilities to existing exploit modules for accurate exploitation.


Metasploit currently has over 1894 exploits, organized under the following platforms: AIX, Android, BSD, BSDi, Cisco, Firefox, FreeBSD, HPUX, Irix, Java, JavaScript, Linux, mainframe, multi (applicable to multiple platforms), NetBSD, NetWare, nodejs, OpenBSD, OSX, PHP, Python, R, Ruby, Solaris, Unix, and Windows

3. Hashcat

Hashcat is a password recovery tool. It had a proprietary code base until 2015, but is now released as open source software. Versions are available for Linux, OS X, and Windows. Examples of hashcat-supported hashing algorithms are Microsoft LM hashes, MD4, MD5, SHA-family, Unix Crypt formats, MySQL, and Cisco PIX.

Hashcat has made its way into the news many times for the optimizations and flaws discovered by its creator, which were exploited in subsequent hashcat releases. (For example, the flaw in 1Password’s password manager hashing scheme.

hashcat used to come in two main variants:

  • hashcat – CPU-based password recovery tool
  • oclHashcat/cudaHashcat – GPU-accelerated tool (OpenCL or CUDA)

Attack types

Hashcat offers multiple attack modes for obtaining effective and complex coverage over a hash’s keyspace. These modes are:

  • Brute-force attack
  • Combinator attack
  • Dictionary attack
  • Fingerprint attack
  • Hybrid attack
  • Mask attack
  • Permutation attack
  • Rule-based attack
  • Table-Lookup attack (CPU only)
  • Toggle-Case attack
  • PRINCE attack (in CPU version 0.48 and higher only)

The traditional bruteforce attack is considered outdated, and the Hashcat core team recommends the Mask-Attack as a full replacement.

4. Aircrack-ng

Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs. It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic. The program runs under Linux, FreeBSD, macOS, OpenBSD, and Windows; the Linux version is packaged for OpenWrt and has also been ported to the Android, Zaurus PDA and Maemo platforms; and a proof of concept port has been made to the iPhone.

In April 2007 a team at the Darmstadt University of Technology in Germany developed a new attack method based on a paper released on the RC4 cipher by Adi Shamir. This new attack, named ‘PTW’, decreases the number of initialization vectors or IVs needed to decrypt a WEP key and has been included in the aircrack-ng suite since the 0.9 release.

Aircrack-ng is a fork of the original Aircrack project. It can be found as a preinstalled tool in many Linux distributions such as Kali Linux or Parrot, which share common attributes as they are developed under the same project (Debian).

5. Kismet

Kismet is a network detector, packet sniffer, and intrusion detection system for 802.11 wireless LANs. Kismet will work with any wireless card which supports raw monitoring mode, and can sniff 802.11a, 802.11b, 802.11g, and 802.11n traffic. The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X. The client can also run on Microsoft Windows, although, aside from external drones (see below), there’s only one supported wireless hardware available as packet source.

Distributed under the GNU General Public License,Kismet is free software.


Kismet differs from other wireless network detectors in working passively. Namely, without sending any loggable packets, 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.[citation needed]

An explanation of the headings displayed in Kismet.

Kismet also 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 can also capture “Per-Packet Information” headers.

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.

In order to find as many networks as possible, 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). The advantage with this method is that it will capture more packets because adjacent channels overlap.

Kismet also supports logging of the geographical coordinates of the network if the input from a GPS receiver is additionally available.


Maltego is software used for open-source intelligence and forensics, developed by Paterva. Maltego focuses on providing a library of transforms for discovery of data from open sources, and visualizing that information in a graph format, suitable for link analysis and data mining. As of 2019, the team of Maltego Technologies headquartered in Munich, Germany has taken responsibility for all global customer-facing operations.

Maltego permits creating custom entities, allowing it to represent any type of information in addition to the basic entity types which are part of the software. The basic focus of the application is analyzing real-world relationships (social networks and computer networks nodes) between people, groups, Webpages, domains, networks, internet infrastructure, and affiliations with online services such as Twitter and Facebook. Among its data sources are DNS records, whois records, search engines, online social networks, various APIs and various meta data.

Maltego is commonly used by security researchers and private investigators.


sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a powerful detection engine, many niche features for the ultimate penetration tester and a broad range of switches lasting from database fingerprinting, over data fetching from the database, to accessing the underlying file system and executing commands on the operating system via out-of-band connections.



Ettercap is a free and open source network security tool for man-in-the-middle attacks on LAN. It can be used for computer network protocol analysis and security auditing. It runs on various Unix-like operating systems including Linux, Mac OS X, BSD and Solaris, and on Microsoft Windows. It is capable of intercepting traffic on a network segment, capturing passwords, and conducting active eavesdropping against a number of common protocols. Its original developers later founded Hacking Team.



Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.

Wireshark is cross-platform, using the Qt widget toolkit in current releases to implement its user interface, and using pcap to capture packets; it runs on Linux, macOS, BSD, Solaris, some other Unix-like operating systems, and Microsoft Windows. There is also a terminal-based (non-GUI) version called TShark. Wireshark, and the other programs distributed with it such as TShark, are free software, released under the terms of the GNU General Public License


Wireshark is very similar to tcpdump, but has a graphical front-end, plus some integrated sorting and filtering options.

Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller’s MAC address. However, when capturing with a packet analyzer in promiscuous mode on a port on a network switch, not all traffic through the switch is necessarily sent to the port where the capture is done, so capturing in promiscuous mode is not necessarily sufficient to see all network traffic. Port mirroring or various network taps extend capture to any point on the network. Simple passive taps are extremely resistant to tampering

On GNU/Linux, BSD, and macOS, with libpcap 1.0.0 or later, Wireshark 1.4 and later can also put wireless network interface controllers into monitor mode.

If a remote machine captures packets and sends the captured packets to a machine running Wireshark using the TZSP protocol or the protocol used by OmniPeek, Wireshark dissects those packets, so it can analyze packets captured on a remote machine at the time that they are captured.
