Wireless networks are accessible to anyone within the router’s transmission radius. This makes them vulnerable to attacks. Hotspots are available in public places such as airports, restaurants, parks, etc.
In this tutorial, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks.
It is impossible to use someone’s WiFi network without their password. However, there are a number of applications that allow you to crack the WiFi network’s password so you can use the network even if you don’t know it. Here’s a list of some of the most popular pieces of WiFi network hacking software available. Some crack the password automatically, Note: some of these applications cost money, while some are free.
Depending on where you live, this could be incredibly illegal. Before you attempt to use any of these applications or methods, contact local law enforcement to learn about your area’s laws regarding WiFi network hacking.
How to Crack Wireless Networks
Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP cracking refers to exploits on networks that use WEP to implement security controls. There are basically two types of cracks namely;
Passive cracking– this type of cracking has no effect on the network traffic until the WEP security has been cracked. It is difficult to detect.
Active cracking– this type of attack has an increased load effect on the network traffic. It is easy to detect compared to passive cracking. It is more effective compared to passive cracking.
WPA uses a 256 pre-shared key or passphrase for authentications. Short passphrases are vulnerable to dictionary attacks and other attacks that can be used to crack passwords. The following tools can be used to crack WPA keys.
CowPatty– this tool is used to crack pre-shared keys (PSK) using brute force attack.
Cain & Abel– this tool can be used to decode capture files from other sniffing programs such as Wireshark. The capture files may contain WEP or WPA-PSK encoded frames.
