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 WiFi networks in use all over the world. If they're like the ones within range of my office, most of them are protected by the WiFi Protected Access or WiFi 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. What I found wasn't encouraging.
It’s now possible to prenetrate the data to obtain every Wi-Fi password. For that, you need to go in a appropriate online website. This blog give a website to get any Wi-Fi password in 2 minutes, and explain the steps. What is cool is that this site is free and its work all over the world ! This server is completely legal. To get the Wi-Fi pasword, you just need tha wifi network name, and be in range. It works for any security encryption (WEP, WPA, WPA2…).
It simply searches for any Wi-Fi network available and connects to them. There is nothing complicated about Wi-Fi Hacker. You can easily hack and bypass any locked Wi-Fi signal that has a password and username.
To deal with it ,you can use a wifi jammer to block the wifi signal.
