WEP Crack Method in Wireless Networks in Ethical Hacking

WEP stands for Wireless Encryption Protocol. This protocol is one of the two most popular data transmission protocols wireless connections use. It provides adequate protection; some variables can be adjusted for even greater protection.

In late 1997, the IEEE Safety Task Group suggested Wired Equivalent Privacy (WEP) provide wireless technology with the same level of protection as wired networks.
It encrypts and decrypts your data by sending 64 bits of information simultaneously. RC4, a stream cypher with an initialization vector (IV), encrypt and decrypts data.
Like all data encryption, WEP operates in text and hexadecimal modes. The encryption algorithm is a simple text string in in-text mode and six 8-bit integers in hexadecimal mode.
If the same encrypted data key is meant to encode more than one data set, the IV must be at least 24 bits long and unique. The IV must be the same even if the data set is larger than 64 bits.
An initialization vector (IV) is used to create the key stream for encryption. RC4 needs an 8-byte IV for WEP keys of 40 or 104 bits, 16 bytes for keys of 128, and 24 bytes for 152 bits. The IV is sent as the content of the message with the information so that the recipient can properly decrypt it.

WEP Crack

There are many ways to circumvent WEP security, but only three can be accomplished with a wireless card. The first is the Man in the Middle Attack, followed by the ARP Cache Poisoning Attack and the Simple WEP Crack. Learn Ethical Hacking Online Course for best coaching. Trainers at FITA Academy provide worthy training with placement assistance.
There was only one a few years ago process known as an ARP Cache Poisoning attack, which allowed anybody with physical access to that system or connected directly to any router or computer on that network to decrypt the data quickly.
However, this method was difficult to implement in practice since it needed physical or login access to a computer.

Usage of Simple WEP Crack

The app is simply present and does not require installation. Find the MAC address of the entry point on the back of the card and enter it into the message box on the main website.
Then choose the encryption type, which I recommend is 64 bits. Then, after a few seconds, click the “Crack” button to get the security code with the percentage of key strength.
Nowadays, most wireless cards, including the Aironet 350 series, support WEP encryption. To see if your card can do this, open a run command and type winipcfg in the Command prompt, followed by entering.

Countermeasures of the Simple WEP Crack Method

Every wifi network is vulnerable to compromise.
A hacker must obtain the appropriate software tools, which are easily available online, and then steal the password or Wi-Fi credentials for the entire network.
Avoiding wireless networks is the only way to prevent a hacker from collecting your wireless connections. Learn the Ethical Hacking course in Bangalore with live projects with the help of well-experienced Instructors and 100% Placement Assistance.
