MUST HAVE this tools for every Hacker

7 Tools for every Hacker

This tools are most important in every hacker, network penetrator's life. They must need these tools. 

1. Nmap :- For network exploration

          Nmap ("Network Mapper") is a free and open source utility for network discovery and security auditing. Many systems and 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 in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer, a flexible data transfer, redirection, and debugging tool, a utility for comparing scan results, and a packet generation and response analysis tool.

2. Nessus Remote Security Scanner :- Vulnerability scanner

          Nessus is a remote security scanning tool, which scans a computer and raises an alert if it discovers any vulnerabilities that malicious hackers could use to gain access to any computer you have connected to a network.  It does this by running over 1200 checks on a given computer, testing to see if any of these attacks could be used to break into the computer or otherwise harm it.

3. Wireshark :- Sniffer

          Wireshark is the world's foremost network protocol analyzer. It lets you see what's happening on your network at a microscopic level. It is the de facto (and often de jure) standard across many industries and educational institutions.

          Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

4. Cain and Abel :- Password recovery tool

          Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol's standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some "non standard" utilities for Microsoft Windows users.

5. Kismet :- Wireless network detector, sniffer, intrusion detection system

          Kismet is a wireless network detector, sniffer, and intrusion detection system. Kismet works predominately with Wi-Fi (IEEE 802.11) networks, but can be expanded via plug-ins to handle other network types.

6. NetStumbler :- Detect WLANs

          NetStumbler (also known as Network Stumbler) is a tool for Windows that facilitates detection of Wireless LANs using the 802.11b, 802.11a and 802.11g WLAN standards. It runs on Microsoft Windows operating systems from Windows 2000 to Windows XP. A trimmed-down version called MiniStumbler is available for the handheld Windows CE operating system.

The program is commonly used for:

• Wardriving

• Verifying network configurations

• Finding locations with poor coverage in a WLAN

• Detecting causes of wireless interference

• Detecting unauthorized ("rogue") access points

• Aiming directional antennas for long-haul WLAN links

7. SuperScan :- Port scanner, pinger, resolver

          SuperScan is a free connect-based port scanning software designed to detect open TCP and UDP ports on a target computer, determine which services are running on those ports, and run queries such as whois, ping, ICMP traceroute, and Hostname lookups.

Superscan 4, which is a completely rewritten update to the other Superscan (version 3, released in 2000), features windows enumeration, which can list a variety of important information dealing with Microsoft Windows such as:

• NetBIOS information

• User and Group Accounts

• Network shares

• Trusted Domains

• Services - which are either running or stopped

Superscan is a tool used by both system administrators, crackers and script kiddies to evaluate a computer's security. System administrators can use it to test for possible unauthorized open ports on their computer networks, whereas crackers use it to scan for a potentially insecure port in order to gain illegal access to a system.
