ThereвЂ™s also an attack against WPS, an unbelievably vulnerable system that many routers ship with enabled by default. RELATED: Don't Have a False Sense of Security: 5 Insecure Ways to Secure Your Wi-Fi YouвЂ™re probably not thatВ special, of course!

Changing the password everyВ six months or every year could also help, but only if you suspect someone is actually spending months of computer power to crack your passphrase. ItвЂ™s clearly a good idea to use a longer password for this reason - 20 characters would take a lot longer to crack than 8. As hardware improves, this process will speed up. If the password is вЂњpasswordвЂќ, it would probably take less than a single second. For a good, long password, it could take years, possibly even hundreds of years or longer. ItвЂ™s tough to say how long it would take to crack a password in this way. 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.ДЄs usual, all these tools are available in Kali Linux (formerly BackTrack Linux), a Linux distribution designed for penetration testing. An attacker wouldnвЂ™t have to be in the same physical area as the network while attempting to crack the passphrase.

As this is an offline attack, it can be performed much more quickly than an online attack. The command tries each possible passphrase against the WPA handshake data until it finds one that fits. These files are generally used to speed up the cracking process. With the raw data captured, an attacker can use a tool like cowpatty or aircrack-ng along with a вЂњdictionary fileвЂќ that contains a list of many possible passwords.

However, theyВ can also perform a вЂњdeauthвЂќ attack, which we covered when we looked at howВ your Wi-Fi network could be cracked. If an attacker waits long enough, theyвЂ™ll be able to capture this four-way handshake data when a device connects. TheyвЂ™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. This handshake isВ WPA2-PSKвЂ™s AchillesвЂ™ heel.ДЄn attacker can use a tool like airodump-ng to monitor traffic being transmitted over the air and capture this four-way handshake. Essentially, this is the negotiation where the Wi-Fi base stationВ and a device set up their connection with each other, exchanging the passphraseВ and encryption information. When a device connects to a WPA-PSK Wi-Fi network, something known as the вЂњfour-way handshakeвЂќ is performed. RELATED: How an Attacker Could Crack Your Wireless Network Security An attacker will have to guess a password and attempt to log into the WI-Fi network with it, so they certainly canвЂ™t guess millions of times per second. We tend to think of Wi-Fi as being only vulnerable to the online attack. (AppleвЂ™s iCloud wasnвЂ™t rate-limiting password guesses in this way, and that helped lead to the huge theft of nude celebrity photos.) Because they donвЂ™t have access to the raw data they can attempt to match passwords against, theyвЂ™reВ limited dramatically. They could guess a few passwords and then Gmail would block them from trying any more passwords for a while. For example, imagine an attacker were trying to gain access to your Gmail account. They do this via вЂњ brute-forcingвЂќ - literally attempting to guess many different possibilitiesВ and hoping one will match.ДЄn online attack is much more difficult and takes much, much longer. Clearly, with access to a password database offline, an attacker can attempt to crack a password much more easily. They can guess millions of times per second, and theyвЂ™re only really limited by how fast their computing hardware is.

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. In an offline attack, an attacker has a file with data they can attempt to crack. There are two types of ways to potentially crack a password, generally referredВ to as offline and online.
