Internet is now the basic need of our daily life. With the increasing use of
smartphones, most of the things are now online. Every time we have to do
something, we just use our smartphone or desktop. This is the reason Wi-Fi
hotspots can be found everywhere.
POPULAR WIRELESS HACKING TOOLS

People also use wireless in their home network to connect all devices.
Every person can see the neighborhood Wi-Fi networks in the system, and
they want to use it for free. But most these networks are secured with a
password key. You need to know this security key to access the network.
When your own network is down, you will desperately want to connect to
these neighborhood networks. For this, people generally search for Wi-Fi
password cracking tools to get unauthorized access to those wireless
networks.
Sometimes when you are on a network, you also want to check what is
happening on the network. This happens mostly in big organizations,
when an employer wants to check who is doing what in the network. For
these things, there are a few network hacking tools available that let
users analyze packets and see what other users are doing.
In this article, I am going to discuss wireless security and best Wi-Fi
password cracking or recovery tools. I will explain the kind of
encryption wireless networks use and how these tools can crack the
networks to get access. We will also see what tools let users monitor
networks.
Wireless Networks and Hacking
Wireless networks are based on IEEE 802.11 standards defined by IEEE (Institute of Electrical and
Electronics Engineers) for ad hoc networks or infrastructure networks. Infrastructure networks have
one or more access points which coordinate the traffic between the nodes. But in ad hoc networks,
there is no access point; each node connects in a peer-to-peer way.
Basically there are two types of vulnerabilities which can be found in the Wireless LAN. One is poor
configuration and the other is poor encryption. Poor configuration is caused by the network admin who
manages the network. It may include the weak password, no security settings, use of default
configurations, and other user related things. Poor encryption is related to security keys used to protect
the wireless network. It is there because of issues in WEP or WPA.

WEP and WPA
WEP and WPA are the two main security protocols used in Wi-Fi LAN. WEP is known as Wired
Equivalent Privacy (WEP). It is a deprecated security protocol which was introduced back in 1997 as a
part of original 802.11 standards. But it was weak, and several serious weakness were found in the
protocol. Now, this can be cracked within minutes. So, a new kind of security protocol was introduced
in 2003. This new protocol was Wi-Fi Protected Access (WPA). It has mainly two versions, 1 and 2
(WPA and WPA2). Now it is the current security protocol used in wireless networks. To get
unauthorized access to a network, one needs to crack these security protocols. There are many tools
which can crack Wi-Fi encryption. These tools can either take advantage of WEP weaknesses or use
bruteforce attacks on WPA/WPA2. I am sure now you know that you should never use WEP security.
Basically wireless hacking tools are of two types. One of which can be used to sniff the network and
monitor what is happening in the network. And other kinds of tools are used to hack WEP/WPA keys.
These are the popular tools used for wireless password cracking and network troubleshooting.

Types of Wireless Hacking
1. Aircrack
Aircrack is one of the most popular wireless passwords cracking tools which you can use for
802.11a/b/g WEP and WPA cracking. Aircrack uses the best algorithms to recover wireless passwords
by capturing packets. Once enough packets have been gathered, it tries to recover the password. To
make the attack faster, it implements a standard FMS attack with some optimizations.
The company behind the tool also offers an online tutorial where you can learn how to install and use
this tool to crack wireless passwords. It comes as Linux distribution, Live CD and VMware image
options. You can use any of these. It supports most of the wireless adapters and is almost guaranteed to
work. If you are using a Linux distribution, the only drawback of the tool is that it requires deeper
knowledge of Linux. If you are not comfortable with Linux, you will find it hard to use this tool. In this
case, try Live CD or VMWare image. VMWare Image needs less knowledge, but it only works with a
limited set of host OS, and only USB devices are supported.
Before you start using this too, confirm that the wireless card can inject packets. Then start WEP
cracking. Read the online tutorial on the website to know more about the tool. If you will follow steps
properly, you will end up getting success with this tool.

2. AirSnort
AirSnort is another popular tool for decrypting WEP encryption on a Wi-Fi 802.11b
network. It is a free tool and comes with Linux and Windows platforms. This tool is no
longer maintained, but it is still available to download from Sourceforge. AirSnort works
by passively monitoring transmissions and computing encryption keys once it has enough
packets received. This tool is simple to use. If you are interested, you can try this tool to
crack WEP passwords.

3. Cain & able
Cain & Able is a popular password cracking tool. This tool is developed to intercept
network traffic and then discover passwords by bruteforcing the password using
cryptanalysis attack methods. It can also recover wireless network keys by
analyzing routing protocols. It you are trying to learn wireless security and
password cracking; you should once try this tool.
4. Kismet
Kismet is the Wi-Fi 802.11 a/b/g/n layer2 wireless network sniffer and IDS. It works
with any Wi-Fi card which supports rfmon mode. It passively collects packets to
identify networks and detect hidden networks. It is built on client/server modular
architecture. It is available for Linux, OSX, Windows and BSD platforms.

5. Netstumbler
NetStumbler is a popular Windows tool to find open wireless access
points. This tool is free and is available for Windows. A trimmed down
version of the tool is also available. It is called MiniStumbler. Basically NetStumblet is used for wardriving, verifying network
configurations, finding locations with a poor network, detecting
unauthorized access points, and more.
But the tool also has a big disadvantage. It can be easily detected by most
of the wireless intrusion detection systems available. This is because it
actively probes a network to collect useful information. Another
disadvantage of the tool is that it does not work properly with the latest
64 bit Windows OS. This is because the tool was last updated back in
April 2004. It has been around 11 years since the last stable release of the
tool.

6. inSSIDer
inSSIDer is a popular Wi-Fi scanner for Microsoft
Windows and OS X operating systems. Initially the tool
was open source. Later it became premium and now
costs $19.99. It was also awarded as “Best
Opensource Software in Networking”. The inSSIDer
Wi-Fi scanner can do various tasks, including finding
open Wi-Fi access points, tracking signal strength, and
saving logs with GPS records.

7. Wireshark
WireShark is the network protocol analyzer. It lets you check what is
happening in your network. You can live capture packets and analyze
them. It captures packets and lets you check data at the micro-level. It
runs on Windows, Linux, OS X, Solaries, FreeBSD and others. WireShark
requires good knowledge of network protocols to analyze the data
obtained with the tool. If you do not have good knowledge of that, you
may not find this tool interesting. So, try only if you are sure about your
protocol knowledge.

8. coWPatty
CoWPAtty is an automated dictionary attack tool for WPA-PSK. It runs on Linux
OS. This program has a command line interface and runs on a word-list that
contains the password to use in the attack.
Using the tool is really simple, but it is slow. That’s because the hash uses SHA1
with a seed of SSID. It means the same password will have a different SSIM. So, you
cannot simply use the rainbow table against all access points. So, the tool uses the
password dictionary and generates the hack for each word contained in the
dictionary by using the SSID.
The new version of the tool tried to improve the speed by using a pre-computed
hash file. This pre-computed file contains around 172000 dictionary file for around
1000 most popular SSIs. But if your SSID is not in those 1000, you are unlucky.

9. Cloud cracker
CloudCracker is the online password cracking tool for cracking
WPA protected Wi-Fi networks. This tool can also be used to
crack different password hashes. Just upload the handshake file,
enter the network name and start the tool. This tool has a huge
dictionary of around 300 million words to perform attacks.

10. Airjack
Airjack is a Wi-Fi 802.11 packet injection tool. This
wireless cracking tool is very useful in injecting forged
packets and making a network down by denial of
service attack. This tool can also be used for a man in
the middle attack in the network.
Conclusion: - In this post, I discussed 10 wireless hacking tools. A few wireless hacking tools are for cracking the
password to get unauthorized access, and a few are for monitoring and troubleshooting the network. But
most of the people really interested in tools to crack wireless hotspots just want to get free Internet
access.
The above collection also contains those tools which try a dictionary attack to crack Wi-Fi passwords to
allow you to get free Internet access. But be sure not to use these tools in a risky place. Hacking wireless
networks to get unauthorized access may be a crime in your country. You may get into trouble for using
these tools. So, please do not use these tools for illegal works. As I already mentioned, you should never
use the WEP encryption key in your home or wireless network. With available tools, it is child’s play to
crack the WEP keys and access your Wi-Fi network.
Wireless monitoring and troubleshooting tools are basically for network admins and programmers
working on Wi-Fi based software. These tools really help when some of your systems face problems in
connecting to the network.
I hope you enjoyed this article and got relevant information about popular wireless hacking and
password cracking tools. I tried my best to compile this list of password hacking tools, but as a human
error
