It takes a lot
of effort and some very good coding skills to develop hacking tools that
are meant for easing out various complex tasks, which if done manually
will consume lots of energy and effort. These tools are available
for free and are either being actively developed by community or their
alternatives are provided. To sum it up, here are top 7 tools every
hacker must possess.
Most hackers are aware of Nmap (Network Mapper) as a free open source
utility for network exploration or security auditing. It helps in
swiftly scanning large networks, Majority of systems and network
administrators find this utility helpful to perform tasks related to
network inventory, managing service upgrade schedules, and monitoring host
or service uptime.
Nmap can run on different types of computers and both console and graphical
versions are available. Not only Nmap is free, but is open source
too. The tool can be useful for beginners (-sT) or by pros (packet_trace). In
short, an extremely versatile tool, once you completely comprehend the
Earlier, Nessus was open source, but it’s still free. The tool works
with a client-server framework. It is in fact the world’s most popular
vulnerability scanner used by over 75,000 organizations across the
world. Several leading organizations could realize major cost savings
with the help of Nessus.
It is a GTK+-based Wiresharknetwork protocol analyzer, or sniffer, that
allows you to describe and browse the contents of network frames. It
aims at creating commercial-quality analyzer for Unix and to lend Wireshark
those features which are missing from closed-source sniffers. The tool
runs perfectly on both Linux and Windows and is easy to use. Moreover,
it can rebuild TCP/IP Streams!
Often referred to as the Swiss knife of hacking tools, Cain & Abel is
actually a password recovery tool used for Microsoft OS. It allows
users to easily recover different types of passwords by sniffing the
network, breaking encrypted passwords with the help of Dictionary,
Brute-Force and Cryptanalysis attacks. It also helps in recording VoIP
conversations, decoding twisted passwords, edifying password boxes,
revealing cached passwords and analyzing routing protocols. The tool
does not use any software vulnerabilities or bugs which are difficult to
fix with little effort.
Kismet refers to an 802.11 layer2 wireless network detector, sniffer, and
infringement detection system. The tool works with any wireless card
that supports raw monitoring (rfmon) mode and can sniff 802.11b, 802.11a,
and 802.11g traffic. It is a good wireless tool if your card supports
Here comes a reasonable wireless tool for Windows! However, it’s not
as strong as its Linux counterparts, but is simple and features a
NetStumbler nice interface. It is good for the basics of
war-driving. NetStumbler is actually a tool for Windows OS that lets
you to identify Wireless Local Area Networks (WLANs) with the help of
802.11b, 802.11a and 802.11g.
SuperScan is a powerful TCP port scanner, pinger, and resolver. It is
an update of most famous Windows port scanning tool, SuperScan. Those
looking for a substitute for nmap on Windows with a decent interface, can
check out this tool.
