Your Wi- Fi’s WPA2 Encryption Can Be Cracked Offline: Here’s How. When it comes to securing your Wi- Fi network, we always recommend WPA2- PSK encryption. It’s the only really effective way to restrict access to your home Wi- Fi network. But WPA2 encryption can be cracked, too — here’s how. As usual, this isn’t a guide to cracking someone’s WPA2 encryption.
It’s an explanation of how your encryption could be cracked and what you can do to better protect yourself. Your Passphrase Can Be Cracked Offline. There are two types of ways to potentially crack a password, generally referred to as offline and online. In an offline attack, an attacker has a file with data they can attempt to crack. For example, if an attacker managed to access and download a password database full of hashed passwords, they could then attempt to crack those passwords. They can guess millions of times per second, and they’re only really limited by how fast their computing hardware is. Clearly, with access to a password database offline, an attacker can attempt to crack a password much more easily.
They do this via “brute- forcing” — literally attempting to guess many different possibilities and hoping one will match. An online attack is much more difficult and takes much, much longer.
For example, imagine an attacker were trying to gain access to your Gmail account. They could guess a few passwords and then Gmail would block them from trying any more passwords for a while. Because they don’t have access to the raw data they can attempt to match passwords against, they’re limited dramatically. Apple’s i. Cloud wasn’t rate- limiting password guesses in this way, and that helped lead to the huge theft of nude celebrity photos.)We tend to think of Wi- Fi as being only vulnerable to the online attack. An attacker will have to guess a password and attempt to log into the WI- Fi network with it, so they certainly can’t guess millions of times per second. Unfortunately, this isn’t actually true.
The Four- Way Handshake Can Be Captured. When a device connects to a WPA- PSK Wi- Fi network, something known as the “four- way handshake” is performed. Essentially, this is the negotiation where the Wi- Fi base station and a device set up their connection with each other, exchanging the passphrase and encryption information. This handshake is WPA2- PSK’s Achilles’ heel. An attacker can use a tool like airodump- ng to monitor traffic being transmitted over the air and capture this four- way handshake. They’d then have the raw data they need to perform an offline attack, guessing possible passphrases and trying them against the four- way- handshake data until they find one that matches. If an attacker waits long enough, they’ll be able to capture this four- way handshake data when a device connects.

Welcome, my hacker novitiates! As part of my series on hacking Wi-Fi, I want to demonstrate another excellent piece of hacking software for cracking WPA2-PSK passwords. WPA. Wi-Fi İttifakı, WPA’yı WEP’in yerine geçecek bir ara önlem olarak ortaya çıkartmıştır. WPA, WEP için dizayn edilmiş olan kablosuz ağ kartlarına.
However, they can also perform a “deauth” attack, which we covered when we looked at how your Wi- Fi network could be cracked. The deauth attack forcibly disconnects your device from its Wi- FI network, and your device immediately reconnects, performing the four- way handshake which the attacker can capture.

With the raw data captured, an attacker can use a tool like cowpatty or aircrack- ng along with a “dictionary file” that contains a list of many possible passwords. These files are generally used to speed up the cracking process.
The command tries each possible passphrase against the WPA handshake data until it finds one that fits. As this is an offline attack, it can be performed much more quickly than an online attack. An attacker wouldn’t have to be in the same physical area as the network while attempting to crack the passphrase. The attacker could potentially use Amazon S3 or another cloud computing service or data center, throwing hardware at the cracking process and speeding it up dramatically. As usual, all these tools are available in Kali Linux (formerly Back. Track Linux), a Linux distribution designed for penetration testing.
