In the context of computer security, a hacker is a person who seeks and exploits weaknesses in the computer system or computer network. Motivation may be intruders by many reasons, such as profit, protest, challenge, enjoyment, or to assess these weaknesses to help remove them. Subculture that has evolved around hackers is often referred to as the computer underground and is now known society. Although there are other uses of the word hacker that relate to the security of the computer, such as referring to someone with an advanced understanding of computers and computer networks, and are rarely used in the prevailing context. They are subject to a long-standing controversy about the real definition of hacker term meaning. In this controversy, the pirates regained term before computer programmers who say that the person who hacked computers, whether criminal computer (black hats) or a computer security expert (white hats), it is called the most suitable cracking instead. She claims some white hat hackers that they also deserve to be pirates title, and should be called that only "crackers black hats."
List of Download Top Best Free Hacking Tools of 2017
#1: Nmap (“Network Mapper”) it is free and open source utility for network discovery and security audit. Many systems and network administrators also find it useful for tasks such as network inventory, schedules upgrade management and control of the host or service uptime service. Uses nmap IP raw new ways packages to determine what hosts are available on the network, what services (application name and version), which provides that the hosts, what operating systems (and versions OS) that are running, filters / firewalls tray type are in use, and dozens of other characteristics. This program has been designed large networks to rapidly scan, but works fine against single hosts. NMB works on all operations of major computer systems and is available official binary packages for Linux, Windows, and Mac OS X. In addition to the classical orders NMB executable line, Suite includes advanced NMB GUI and results viewer user, flexible data transfer, redirection, and debugging tool, to compare the results of the survey, the instrument package generation and analysis of the response.
#2: Wireshark it is the foremost network protocol analyzer in the world. It lets you see what's happening on the network at the microscopic level. It is actually (and often de jure) standard in many industries and educational institutions. Wireshark development thrives thanks to the contributions of networking experts worldwide. This is a continuation of a project that began in 1998. The Wireshark has a rich feature set that includes inspection in the depths of hundreds of protocols, with more being added all the time. Moreover, it includes the arrest of Live and offline analysis.
#3: Nessus is a proprietary scanner Comprehensive weaknesses that have been developed by the Network Security acceptor. It is free for personal use in non-project environment. According to surveys done in 2009 by sectools.org, Nessus is the world's most popular vulnerability scanner, the resolution in the first place in 2000 and 2003, and 2006 security tools survey. It estimated tenable Network Security 2005 that was used by more than 75,000 organizations worldwide. Nessus scans allows for the following types of vulnerabilities:
- Vulnerabilities that allow a remote hacker to control or access 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 against the TCP/IP stack by using malformed packets
- Preparation for PCI DSS audits
Initially, Nessus and consisted of two main components; nessusd, Nessus daemon, which does not scan, and nessus, the client, which controls the scanning and presents the results of exposure to the user. Later versions of Nessus (4 and older) to take advantage of the web server, which provides the same functionality as the client.
#4: NetStumbler (Also known as the struggling network) is a Windows utility that facilitates the detection of wireless local area networks using the 802.11b, 802.11a and 802.11g WLAN standard criteria. It runs on Microsoft Windows operating systems from Windows 2000 to Windows XP. A version trimmed down so-called MiniStumbler available for the operating system Windows CE handheld. This 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
#5: Kismet it is to detect a network device, and smell, and the intrusion detection system 802.11 wireless LANs. Kismet will work with any wireless card which supports raw monitoring mode, and can sniff 802.11a, 802.11b and 802.11g standard, and the movement of the standard 802.11n. The program works in Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X. Also the client can run on Microsoft Windows, though, aside from the aircraft without external pilot (see below), there is only one support wireless devices for free as a source package .
Division differs from the disclosure of other wireless network at work negatively devices. It is, without sending any packets Loggable, it is able to detect the presence of each wireless access point wireless network customers, and link them with each other. It is also yet open source wireless control device used on a large scale. An explanation of the titles displayed in the division. 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 record all packets sniffed and saved in Wireshark or Airsnort Chbdomb shape / compatible file. Kismet can also capture the heads "of each packet of information." It also features a division the ability to detect default or networks "is not configured", and requests an investigation, and determine what level of wireless encryption is used on a given access point.
In order to find as many networks as possible, the division supports the navigation channel. This means that it is constantly changing from channel to channel non-sequentially, in sequence knowledge with a default value that leaves large holes between channels (for example, 1-6-11-2-7-12-3-8- 04/09/13 -14-5-10). The advantage of this method is that it capture more packets because adjacent channels will interfere. Kismet also supports recording the geographical coordinates of the network if the input from the GPS receiver device is available in addition.
#6: Cain & Abel it is the password for Microsoft operating systems recovery tool. It allows easy recovery of various kind of passwords type by sniffing the network, cracking passwords encrypted using Dictionary, Brute-force attacks cryptanalysis, recording conversations VoIP, decoding secret mixture of words, restore the wireless network keys, revealing password boxes, reveal passwords stored temporarily and analyzing routing protocols. The program does not exploit any loophole or software errors that can not be fixed with a little effort. It covers some of the current security / vulnerability aspects in the protocol standards, authentication methods and caching mechanisms. Its main purpose is to restore a simplified passwords and credentials from various sources, but also ships some "non-standard" facilities for users of Microsoft Windows.
It has been the development of Cain and Abel, hoping to be useful for network administrators, teachers, security consultants / professionals and forensic staff, security vendors and professional software penetration testing and everyone should plan to use it for ethical reasons. The author does not help or support any illegal activity done with this program.
