Hack Neighbors Wifi Using Cmd' title='Hack Neighbors Wifi Using Cmd' />How I cracked my neighbors Wi. Fi password without breaking a sweat. Last weeks feature explaining why passwords are under assault like never before touched a nerve with many Ars readers, and with good reason. After all, passwords are the keys that secure Web based bank accounts, sensitive e mail services, and virtually every other facet of our online life. Lose control of the wrong password and it may only be a matter of time until the rest of our digital assets fall, too. Take, for example, the hundreds of millions of Wi. How To Connect To Neighbors WifiFi networks in use all over the world. If theyre like the ones within range of my office, most of them are protected by the Wi. Fi Protected Access or Wi. Fi Protected Access 2 security protocols. In theory, these protections prevent hackers and other unauthorized people from accessing wireless networks or even viewing traffic sent over them, but only when end users choose strong passwords. I was curious how easy it would be to crack these passcodes using the advanced hardware menus and techniques that have become readily available over the past five years.

Whats more, WPA and WPA2 passwords require a minimum of eight characters, eliminating the possibility that users will pick shorter passphrases that could be brute forced in more manageable timeframes. WPA and WPA2 also use a networks SSID as salt, ensuring that hackers cant effectively use precomputed tables to crack the code. Thats not to say wireless password cracks cant be accomplished with ease, as I learned firsthand. I started this project by setting up two networks with hopelessly insecure passphrases. The first step was capturing what is known as the four way handshake, which is the cryptographic process a computer uses to validate itself to a wireless access point and vice versa. This handshake takes place behind a cryptographic veil that cant be pierced.

With less than two hours practice, I was able to do just that and crack the dummy passwords secretpassword and tobeornottobe I had chosen to protect my test networks. Brother, can you spare a deauth frameTo capture a valid handshake, a targeted network must be monitored while an authorized device is validating itself to the access point. This requirement may sound like a steep hurdle, since people often stay connected to some wireless networks around the clock. Its easy to get around, however, by transmitting whats known as a deauth frame, which is a series of deauthorization packets an AP sends to client devices prior to it rebooting or shutting down. Devices that encounter a deauth frame will promptly rejoin an affected network. Using the Silica wireless hacking tool sold by penetration testing software provider Immunity for 2,5. I had no trouble capturing a handshake established between a Netgear WGR6. Mac. Book Pro. Indeed, using freely available programs like Aircrack ng to send deauth frames and capture the handshake isnt difficult. The nice thing about Silica is that it allowed me to pull off the hack with a single click of my mouse. In less than 9. 0 seconds I had possession of the handshakes for the two networks in a pcap thats short for packet capture file. My Mac never showed any sign it had lost connectivity with the access points. Enlarge A screenshot showing Immunity Inc. Silica wireless penetration testing tool in action as it sends a deauth frame and then captures the resulting four way handshake. Dan Goodin. I then uploaded the pcap files to Cloud. Cracker, a software as a service website that charges 1. Wi. Fi password against about 6. Within seconds both secretpassword and tobeornottobe were cracked. A special WPA mode built in to the freely available ocl. Hashcat Plus password cracker retrieved the passcodes with similar ease. It was the neighborly thing to do. Cracking such passcodes I had set up in advance to be guessed was great for demonstration purposes, but it didnt provide much satisfaction. What I really wanted to know was how much luck Id have cracking a password that was actually being used to secure one of the networks in the vicinity of my office. So I got the permission of one of my office neighbors to crack his Wi. Fi password. To his chagrin, it took Cloud. Cracker just 8. 9 minutes to crack the 1. I relied on a premium, 1. My fourth hack target presented itself when another one of my neighbors was selling the above mentioned Netgear router during a recent sidewalk sale. When I plugged it in, I discovered that he had left the eight character Wi. Fi password intact in the firmware. Remarkably, neither Cloud. Cracker nor 1. 2 hours of heavy duty crunching by Hashcat were able to crack the passphrase. The secret a lower case letter, followed two numbers, followed by five more lower case letters. There was no discernible pattern to this password. It didnt spell any word either forwards or backwards. I asked the neighbor where he came up with the password. He said it was chosen years ago using an automatic generation feature offered by Earth. Link, his ISP at the time. The e mail address is long gone, the neighbor told me, but the password lives on. No doubt, this neighbor should have changed his password long ago, but there is a lot to admire about his security hygiene nonetheless. By resisting the temptation to use a human readable word, he evaded a fair amount of cutting edge resources devoted to discovering his passcode. Since the code isnt likely to be included in any password cracking word lists, the only way to crack it would be to attempt every eight character combination of letters and numbers. Such brute force attacks are possible, but in the best of worlds they require at least six days to exhaust all the possibilities when using Amazons EC2 cloud computing service. WPAs use of a highly iterated implementation of the PBKDF2 function makes such cracks even harder. Besides changing the password every six months or so and not using a 1. Wi. Fi security. WPA allows for passwords with 6. Yes, the gains made by crackers over the past decade mean that passwords are under assault like never before. Its also true that its trivial for hackers in your vicinity to capture the packets of the wireless access point that routes some of your most closely held secrets. But that doesnt mean you have to be a sitting duck. When done right, its not hard to pick a passcode that will take weeks, months, or years to crack. With odds like that, crackers are likely to move onto easier targets, say one that relies on the quickly guessed secretpassword or a well known Shakespearean quote for its security.
