I have got a wireless router, configured it to allow all my systems to access internet wirelessly and checked that everything is running smoothly. But few times I see unauthorized connection attempts to my Wi-Fi network. So, I googled about this and learned that it’s very crucial to take all necessary steps to enhance the security level of your Wi-Fi network. Then again I also came across few Wi-Fi hacking tools that allow to hack into someone’s Wi-Fi network and access their resources for free.

In today’s era it’s very dangerous to leave your Wi-Fi network unguarded. It’s possible for anyone to use your Wi-Fi network and send unauthorized emails. Terrorism or threatening emails can get you into serious trouble, even if you are not related to this in any way, as your Wi-Fi details are logged with the email service provider and partially in the email header.

Let’s know the top 5 Wi-Fi hacking tools first, understand how they work and then we will work out on the best-practices to increase the Wireless Router security.

Kismet

Using Kismet one can see all the open wireless networks, as well as those Wireless Networks which dont broadcast their SSID’s. It’s a matter of minutes to use this tool and identify networks around you.

Technically Kismet is an 802.11 layer 2 wireless network detector, sniffer, and intrusion detection system. It works with all wireless cards that support rfmon (raw monitoring) mode, and can sniff 802.11b, 802.11a, 802.11g, and 802.11n traffic.

Kismet typically identifies networks by collecting packets passively and detecting standard named networks, detecting hidden networks, and inferring the presence of nonbeaconing networks via data traffic.

NetStumbler

NetStumbler is a freeware Wi-Fi hacking tool that’s compatible with Windows only. It can be used to search open wireless networks and establish unauthorized connections with them.

NetStumblr can also track the Signal/Noise condition to negotiate a strong Wi-Fi connectivity with the network. Checkout the below video to see how it works.

WireShark

Wireshark Wi-Fi hacking tool not only allows hackers to find out all available wireless networks, but also keeps the connection active and helps the hacker to sniff the data flowing through the network.

You can use WireShark to capture network packets and to display that packet data as detailed as possible. It also helps in examining HTTP Requests, Cookies, Forms, TCP Requests, Ping Requests and responses etc.

AirSnort

Most Wi-Fi hacking tools work only when there is no encrypted security settings. While NetStumblr and Kismet fail to work if there is a wireless encyption security being used, AirSnort works like a charm and does the magic here.

All other functionality remains same, but AirSnort is used by hackers to hack into a Wi-Fi hotspot with more tight security measures.

CowPatty

CowPatty is an another Wi-Fi network hacking tool that has crack got a WPA-PSK protection feature and using this hackers can even break into more secure Wi-Fi environments.

CowPatty actually tries a bunch of different options from a dictionary file and checks if it matches with a defined pre-shared key. Below is the demo video on the way it works.

Secure Wi-Fi Networks from Hackers

With the release of advanced Wi-Fi hacking tools and methods, it’s practically impossible to keep your Wi-Fi hostpot secure from the evil eyes. However, you can always use the followings steps to minimize the chances of hackers hacking into your Wi-Fi network.

1. Have a MAC level filtering at your router.

2. Change the default settings (user ID, password, Access point, etc) of your router.

3. Encrypt and do not broadcast your SSID.

4. If you use WEP, use a 128-bit, not a 40-bit WEP encryption key.  128 bit key would take longer to crack.  If your wireless router supports it , use WPA or WPA2 instead of WEP. WPA / WPA2 is much secure as compared to WEP.

5.) Use a long and complex WPA Pre-Shared Key (use random letters, digits and symbols).  This type of key would have less of a chance of residing in a dictionary file that would be used to try and guess your key and/or would take longer.

6.) Ensure that you send your login data using HTTPS. Traffic sent over the HTTPS protocol is encrypted, therefore anyone sniffing packets over the network will get garbled text and nothing else.
