Tutorial: Create Wordlists with Crunch

Greetings all. Before I get into the tutorial, I would like to mention that I am fairly new to Null Byte (been lurking for some time though), and what really appeals to me about this place is its tight, family-like community where everyone is always willing to help each other and the constant search for knowledge that inhabits this subdomain is a driving motivator for me to join in. I'm glad I arrived at the right time. Anyway, wipes tears (not really)...

How To: This Is the Quickest Way to Add a New Contact on Any Phone

The awkward silence when you're adding someone's name and number to your contacts is worse than usual since you're meeting a new person and this is part of their first impression of you. So don't get labeled as clumsy or slow before you even get a chance to network with your new contact — just whip out your phone and confidently showcase this trick instead.

How To: See Your iPhone's Actual Signal Strength for Cellular Reception

The signal bars in your iPhone's status bar are great visual indicators for knowing how good your cellular reception is, but they're not very accurate. Instead of showing the actual amount of signal you're receiving, they just give you a general range, and you'll have no idea if three out of four bars is actually a good connection or not. But there is a trick to see the real numbers.

How To: Exploit Shellshock on a Web Server Using Metasploit

One of the most critical bugs to come out in the last five years was Shellshock, a vulnerability which allows attackers to execute arbitrary code via the Unix Bash shell remotely. This vulnerability has been around for a while now, but due to the ubiquity of Unix machines connected to the web, Shellshock is still a very real threat, especially for unpatched systems.

How To: Activate Your Samsung Galaxy's Vault to Keep Your Apps, Files, and History Safe from Prying Eyes and Hackers

One UI has an exciting privacy feature that lets you lock apps, photos, videos, and files on your Galaxy device behind Samsung's defense-grade Knox security platform. Only you can unlock it using a pattern, PIN, or passcode, or with biometrics like fingerprint and iris locks. It's like having a safe built right into your smartphone, and it couldn't be easier to set up.

How To: Dehydrate Food Without a Dehydrator

I grew up in a rural town, and that meant that we dehydrated a lot of food. Even with a hungry family of five, there was no way that we could eat all of the season's tomatoes before they molded, or all of the orchard's apples before they grew soft, or all of the wild mushrooms that we picked. And so our dehydrator was always getting a good workout.

How To: Uninstall Bloatware Without Root or a PC Using Android's New 'Wireless Debugging' Feature

Bloatware is a problem on Android, and it's not just a Samsung thing. Removing apps that have the Uninstall or Disable button grayed out in Settings has always involved sending ADB commands to your phone from a computer, which itself was always such a pain to set up. Thankfully, that has finally changed.

How To: Perform Advanced Man-in-the-Middle Attacks with Xerosploit

A man-in-the-middle attack, or MitM attack, is when a hacker gets on a network and forces all nearby devices to connect to their machine directly. This lets them spy on traffic and even modify certain things. Bettercap is one tool that can be used for these types of MitM attacks, but Xerosploit can automate high-level functions that would normally take more configuration work in Bettercap.

How To: Use Google Maps or Waze with Siri Instead of Apple Maps

When driving, you can get directions hands-free by asking Siri. You can also make general map searches, show a location's details, call a query's phone number, and view traffic details. However, Siri defaults to Apple Maps for all those. If you prefer Google Maps, Waze, or another third-party navigation app, the map-based Siri commands won't work. But that doesn't mean you can't still use Siri.

How To: Exploit Java Remote Method Invocation to Get Root

In the world of technology, there's often a trade-off between convenience and security. The Java Remote Method Invocation is a system where that trade-off is all too real. The ability for a program written in Java to communicate with another program remotely can greatly extend the usability of an app, but it can also open up critical vulnerabilities that allow it to be compromised by an attacker.

How To: Use an ESP8266 Beacon Spammer to Track Smartphone Users

Smartphones and laptops are constantly sending Wi-Fi radio signals, and many of these signals can be used to track us. In this guide, we'll program a cheap IoT device in Arduino to create hundreds of fake networks with common names; This will cause nearby devices to reveal their real trackable MAC address, and it can even let an attacker take over the phone's data connection with no warning.

How To: Keep Law Enforcement Out of Your Android Device

With protests springing up across America, there's a chance you may have your first interaction with law enforcement. Many demonstrators will have their phones in-hand to film the action, which, sadly, could prompt an officer to demand the device and any self-incriminating data it may contain. Before this happens, you should know there are tools at your disposal to protect your data in such situations.

How To: Seamlessly Transfer a FaceTime Call to Your iPhone, iPad, or Mac Without Disconnecting It

One advantage to using Apple's ecosystem is Continuity, which allows you to move files, media, and tasks seamlessly between all your Apple devices. It even lets you use one device to help with actions on another, like unlocking your Mac with your Apple Watch or using your iPad as a second display. Now, things are even better with Continuity with Handoff's new FaceTime functionality.

How To: High Heart Rate Warning on Your Apple Watch? Here's What That Means

Your Apple Watch sends you notifications from friends, family, and the apps that are important to you. Occasionally, however, the watch may scare the heck out of you with a notification warning of an abnormal, elevated heart rate. If you have no history of heart conditions, this alert might come as a shock. Why do you have a high heart rate, and what are you to do with the information?

How To: Hack Wi-Fi Networks with Bettercap

There are many tools out there for Wi-Fi hacking, but few are as integrated and well-rounded as Bettercap. Thanks to an impressively simple interface that works even over SSH, it's easy to access many of the most powerful Wi-Fi attacks available from anywhere. To capture handshakes from both attended and unattended Wi-Fi networks, we'll use two of Bettercap's modules to help us search for weak Wi-Fi passwords.

How To: Scan, Fake & Attack Wi-Fi Networks with the ESP8266-Based WiFi Deauther

The price of hacking Wi-Fi has fallen dramatically, and low-cost microcontrollers are increasingly being turned into cheap yet powerful hacking tools. One of the most popular is the ESP8266, an Arduino-programmable chip on which the Wi-Fi Deauther project is based. On this inexpensive board, a hacker can create fake networks, clone real ones, or disable all Wi-Fi in an area from a slick web interface.

How To: Spot a Liar Through Text Messages

While text messaging has become one of the most frequent ways we communicate with our friends, the missing body language, tone of voice, and eye contact can make it difficult to tell when someone is being dishonest. That said, it's not impossible. There are a number of subtle hints you can train yourself to recognize that will to help you detect written lies hiding in your SMS and iMessages. Here's what you should look out for.

How to Hack Wi-Fi: Choosing a Wireless Adapter for Hacking

Welcome back, my budding hackers. So many of you are interested in hacking Wi-Fi that I have decided to revisit my Wi-Fi Hacking series with some updated and more in-depth material. I strongly suggest that you look at some of my earlier posts, such as "Getting Started with Terms and Technologies" and "Getting Started with the Aircrack-ng Suite of Wi-Fi Hacking Tools," before continuing here. If you're ready, you can also check out our updated 2017 buying guide here.

How To: Play Sound from 2 Apps at Once on Your Samsung Galaxy Phone

On a PC, you can play sound from multiple apps at once. It's great, but it can also be confusing — there's a volume slider in each app, then the system-wide one, and probably another knob on your speakers. To avoid this dysfunction, Android only has one sound stream for media. But that has its own problems.
