How to Hack Wi-Fi: Get Anyone's Wi-Fi Password Without Cracking Using Wifiphisher

Welcome back, my tenderfoot hackers! Do you need to get a Wi-Fi password but don't have the time to crack it? In previous tutorials, I have shown how to crack WEP, WPA2, and WPS, but some people have complained that cracking WPA2 takes too long and that not all access points have WPS enabled (even though quite a few do). To help out in these situations, I present to you an almost surefire way to get a Wi-Fi password without cracking—Wifiphisher.

How To: Set Up a Headless Raspberry Pi Hacking Platform Running Kali Linux

The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.

How To: Hack WPA & WPA2 Wi-Fi Passwords with a Pixie-Dust Attack Using Airgeddon

Design flaws in many routers can allow hackers to steal Wi-Fi credentials, even if WPA or WPA2 encryption is used with a strong password. While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. To do this, a modern wireless attack framework called Airgeddon is used to find vulnerable networks, and then Bully is used to crack them.

How To: Hack Open Hotel, Airplane & Coffee Shop Wi-Fi with MAC Address Spoofing

After finding and monitoring nearby wireless access points and devices connected to them, hackers can use this information to bypass some types of security, like the kind used for Wi-Fi hotspots in coffee shops, hotels, and in flights high above the ground. By swapping their MAC address for that of someone already connected, a hacker can bypass the MAC filter and connect freely.

How To: Hack WPA WiFi Passwords by Cracking the WPS PIN

A flaw in WPS, or WiFi Protected Setup, known about for over a year by TNS, was finally exploited with proof of concept code. Both TNS, the discoverers of the exploit and Stefan at .braindump have created their respective "reaver" and "wpscrack" programs to exploit the WPS vulnerability. From this exploit, the WPA password can be recovered almost instantly in plain-text once the attack on the access point WPS is initiated, which normally takes 2-10 hours (depending on which program you use).

How To: The Hacks Behind Cracking, Part 1: How to Bypass Software Registration

If you've ever wondered how software pirates can take software and crack it time and time again, even with security in place, this small series is for you. Even with today's most advanced methods of defeating piracy in place, it is still relatively easy to crack almost any program in the world. This is mainly due to computer processes' ability to be completely manipulated by an assembly debugger. Using this, you can completely bypass the registration process by making it skip the application'...

How To: Create Bootable USB with Persistence for Kali Linux

Recently I was trying to install Kali Live on a USB drive with persistence and struggled to find a tutorial online that was simple and actually worked. After some trial and error I figured out how to do it correctly and decided to make an article for anyone who is experiencing the same difficulty I did. You will need an USB with at least 8GB. Mine is 132GB, nice and large.

How To: Find Anyone's Private Phone Number Using Facebook

Facebook really wants your phone number, nagging you for one as soon as you join. This isn't all bad since it can help secure your account with two-factor authentication. On the flipside, this makes it easy to reveal the private phone numbers of virtually anyone on Facebook, including celebrities and politicians. We're going to look at how a hacker would do this and how to protect yourself.

How To: Use SELinux Targeted Policy to Secure Your Hosts

Hackers often rely on lazy system admins and unpatched vulnerabilities to get access to a host. Keeping intruders off of our machines requires us to update daily, only run the services we need, and read the code, among other things, but we can still make mistakes. Luckily for us, we can limit the damage caused by those mistakes by running SELinux.

Hack Like a Pro: How to Crack Online Web Form Passwords with THC-Hydra & Burp Suite

Welcome back, my hacker novitiates! In an earlier tutorial, I had introduced you to two essential tools for cracking online passwords—Tamper Data and THC-Hydra. In that guide, I promised to follow up with another tutorial on how to use THC-Hydra against web forms, so here we go. Although you can use Tamper Data for this purpose, I want to introduce you to another tool that is built into Kali, Burp Suite.

C/C++ Programming for Hackers: Part 1 (Introduction)

Hello my fellow hackers! Since i am new here, i'd first like to introduce myself: i am Phoenix750, a young passionated hacker who likes to share everything he knows with other people of my kind. I have been reading null byte for quite some time now, but only could register today. I truely love how this community respects newcomers, But even after reading a lot of tutorials on here, i never came accross a good programming tutorial (except the scripting tutorials, but scripting isn't programmin...

How to Hack Wi-Fi: Capturing WPA Passwords by Targeting Users with a Fluxion Attack

With tools such as Reaver becoming less and less viable options for penetration testers as ISPs replace vulnerable routers, there becomes fewer certainties about which tools will work against a particular target. If you don't have time to crack the WPA password, or it is unusually strong, it can be hard to figure out your next step. Luckily, nearly all systems have one common vulnerability you can count on—users!

How to Hack Wi-Fi: Creating an Evil Twin Wireless Access Point to Eavesdrop on Data

Welcome back, my greenhorn hackers! Now that we're familiar with the technologies, terminology, and the aircrack-ng suite, we can finally start hacking Wi-Fi. Our first task will be to creating an evil twin access point. Many new hackers are anxious to crack Wi-Fi passwords to gain some free bandwidth (don't worry, we'll get to that), but there are so many other Wi-Fi hacks that are far more powerful and put so much more at risk than a bit of bandwidth.
