He said it was chosen years ago using an automatic generation feature offered by EarthLink, 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 isn't 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 Amazon's EC2 cloud computing service.
Besides changing the password every six months or so and not using a digit phone number, my neighbors could have taken another important step to improve their WiFi security.
WPA allows for passwords with 63 characters in them, making it possible to append four or five randomly selected words—"applesmithtrashcancarradar" for instance—that are easy enough to repeat to guests who want to use your wireless network but are prohibitively hard to crack.
Yes, the gains made by crackers over the past decade mean that passwords are under assault like never before. It's also true that it's 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 doesn't mean you have to be a sitting duck.
When done right, it's 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.

Brother, can you spare a deauth frame? If it is enabled, WPS can be easily cracked within 24 or less in many cases hours by breaking down the 8-character PIN into 2 halves, and cracking those halves. The 8th digit is actually a checksum of the first 7, so really you only have to guess the first 7. This amounts to 11,! And, allowed size of password is 64 characters. I hate to tell you this but yes, doing it on your own can take forever.
The tool is fluxion. Instead of doing this, it performs a little bit of phishing where the already connected user is asked to enter password of WiFi network again for security reason and when the user enter the password, first the handshake is checked with the earlier captured handshake of the device, if handshake is correct that means the password entered by user is correct.
Once it is successful, Fluxion returns the key required to authenticate the network. Read Complete Writte. Anyone in the WiFi range can connect his device to the network without any password in enjoy free internet.
However, these networks are rarely available and also risky. Enter the following command in terminal: It will show you the output like this: Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. It will show you what network interface are you using. In my system, I have only one network interface card wlan0 , which is my wireless interface card.
Create a network interface which runs in monitor mode. In this step, you have to reference a dictionary file containing all the combinations of the password, that aircrack-ng tool will use.
That is why, a good dictionary file is a most important element here. I have a feeling, that after going through the last sections of this tutorial, you will already have some idea, what should be done in order to make WPA cracking not possible or rather say: impossible within a reasonable period of time.
It has a direct impact on the encryption scheme used by a suite. To make it computationally impossible, use a password of at least 10 characters composed of random combination not any plain word that you can meet in any dictionary of lower case, upper case, special characters and digits. This 8-digit is a very short work for a brute-force attack, and also this 8-digit may be found on the back of the AP box itself. Do you have WPS feature enabled on your home router?
Ashraf Said. Lazaro Diaz. It can take time to all the available WiFi networks in range. First enter the command airplay-ng -1 0 -a FB:A9:B1 mon0 to perform fake authentication -1 in command to the network.
Hit enter and the command will start doing attack to WEP WiFi Access point and you can see the Data value increasing at enormously fast rate. In below screenshot the bell Once you have enough data in the file bell It will test all the data values available in key file and automatically show you the key it found by testing data in file. It will be in hex format but work just fine. Now, to use this key, firstly start the processes you have killed in Step 1 above using the command I have used below.
Finally enter the cracked key without colon as the password of targeted WEP WiFi Network and it will be connected. Tags: Hack WiFi X. Saurabh Saha March 14, Saurabh Saha. Through his popular technology blogs: TechGYD.
