Hacking tools here means the tools or the software used to gather information of network or website. These tools could also be used by most of the hackers. There are a number of tools for different purposes. The tools listed here widely used. Moreover make sure you have the permission to run these tools otherwise it is illegal.
1. Nmap (Network Mapper): To explore the networks Nmap is mostly used tool. Nmap is a free and also an open source tool. Security auditing could be easy with the use of this tool. Rapidly scanning of network is its major task. With the use of IP packets it determines what type of hosts are present in a network along with information on the applications being used by them. Nmap also gives information about the operating systems used by the networks. It is helpful to identify the firewalls in a network and many more other characteristics of any given host.
2. Wireshark: Wireshark is a packet analyzer. It is a free and also an open-source. A network engineer use wireshark for troubleshooting, network analysis, education, software and communication protocol development. It’s original named was Ethereal, but in May 2006 the project was renamed with a new name Wireshark. It happens only due to trademark issue.
3. Nessus: Nessus Remote Security Scanner has become closed source software in the year 2005, but the engine that runs the software is still free of cost. 75000 organizations world-wide are using the Nessus Security Scanner. So Nessus has been become the world’s most popular scanner. Many have befitted from this software and it is being used extensively in auditing critical enterprise devices.
4. Kismet: For 802.11 wireless LANs, Kismet works as network detector, packet sniffer, and intrusion detection system. It is also compatible with all the wireless cards, which supports raw monitoring mode, and can sniff 802.11a, 802.11b, 802.11g, and 802.11n traffic. This is available for Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X. Kismet is also available for Microsoft Windows in GUI version. Aside from all external drones, Kismet is only supported wireless hardware available as packet source.
5. LCP: In Windows NT/2000/XP/2003, LCP could be used for user account passwords auditing and recovery, Brute force session distribution, Hashes computing and Passwords recovery. It is very good free alternative to L0phtcrack.
6. Yersinia: In different Layer 2 protocols there are some weaknesses. So this network tool has been designed to take advantage of these weaknesses. It acts like a solid framework for analyzing and testing the deployed networks and systems, but in actual it is not a framework. Currently, the following network protocols are implemented: IEEE 802.1q, Spanning Tree Protocol (STP), Dynamic Host Configuration Protocol (DHCP), Hot Standby Router Protocol (HSRP), Inter-Switch Link Protocol (ISL), VLAN Trunking Protocol (VTP), Dynamic Trunking Protocol (DTP), Cisco Discovery Protocol (CDP).
7. Nikto: It is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 3200 potentially dangerous files/CGIs, versions on over 625 servers, and version specific problems on over 230 servers. The plugins used by it needs to be update at proper timess and it could be updated automatically.
8. SuperScan: SuperScan is a very powerful tool which works as connect-based TCP port scanner, pinger and hostname resolver. This program is extremely fast and versatile due to multithreaded and asynchronous techniques which developers used to make it. For network administrators, this is first and foremost tool. Do not scan those systems which are not under your control. It will be illegal. To use this program against computers on the Internet that you have no right to scan since you are highly likely to be tracked down and attract the attention of your ISP, possibly resulting in your account being terminated.
9. John the Ripper: John the Ripper is a fast password cracker, currently available for many flavours of Unix, DOS, Win32, BeOS, and OpenVMS. The weak passwords of any operating system could be crack by using it. Besides several crypt password hash types most commonly found on various Unix flavours, supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.
10. Cain and Abel: In Microsoft Operating Systems Cain and Abel works as a password recovery tool. With the help of decoding scrambled passwords, recording VoIP conversations, sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, uncovering cached passwords, recovering wireless network keys, revealing password boxes, and analyzing routing protocols, it allows easy recovery of various type of passwords
