How To: Set Up Contact Key Verification for the Highest Level of iMessage Security

Your iPhone is fairly secure by default, but Apple's Lockdown Mode takes it to Fort Knox levels of protection. If you're a high-value target for spyware, phishing attempts, and other sophisticated cyberattacks, it's an essential feature. But for almost everyone else, it's an extreme move. If you simply want to verify someone's identity when chatting, Contact Key Verification is a more practical option.

How To: Bypass Paywalls in Safari to Read Any Article on Your iPhone

Paywalls make it nearly impossible to access certain content unless you have a subscription. It's a practice that many news organizations and other online publications use to increase revenue: The New York Times, The Wall Street Journal, Vanity Fair, Wired, and so many more. But just because a paywall is in place doesn't mean you can't get around it on your iPhone.

Making Electromagnetic Weapons: EMP Generator, Part One

In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...

Modular Origami: How to Make a Truncated Icosahedron, Pentakis Dodecahedron & More

Last post, the Sonobe unit was introduced as a way to use multiple copies of a simply folded piece of paper to make geometric objects. In this post, we are going to explore that concept further by making two more geometric models. The first is the truncated icosahedron, which is a common stitching pattern for a soccer ball. The second was supposed to be the pentakis dodecahedron, but through systematic errors last night, I actually built a different model based off of the rhombic triacontahed...

How To: Skip the Oven—Microwave Your Fish

Fish are delicate, flaky, and can be damn tricky to cook; more often than not, you end up with a hard, dry block of flesh that makes your taste buds sad. And the best ways to cook fish that you know of—c'mon, who doesn't love a fried fish—take way too much effort for you to bother with on a weeknight. Or maybe you're looking for a healthier way to enjoy fish that doesn't require batter or frying at all.

How To: Enable Monitor Mode & Packet Injection on the Raspberry Pi

The Raspberry Pi Zero W and Pi 3 Model B+ include integrated Wi-Fi, Bluetooth Low Energy, and more than enough power to run Kali Linux. They sound like perfect all-in-one penetration testing devices, but the lack of support for monitor mode and packet injection usually meant buying a supported Wi-Fi adapter. Now, it's possible to use monitor mode on the built-in Wi-Fi chip with Nexmon.

How To: There's an Easy Way to Type Fractions as Single Characters on Your iPhone's Keyboard

Whenever you need to type out a fraction on your iPhone, whether in a message, word document, presentation, math problem, recipe, or wherever else you need it, it's easy to use numbers and slashes. But there's a way to make fractions look more professional and easier to read straight from your keyboard.

How To: Annoy Your Friends on iMessage with a Barrage of Automated Texts

Back in its infancy, the App Store was filled with text bomb apps that allowed users to send a barrage of text messages to friends, family, and foes. It was a fun way to annoy people, but Apple quickly scrubbed the apps because of technical issues. Although text bombs are still banished, you can now use a Siri Shortcut to send text bombs through iMessage on your iPhone.

News: Always-Updated List of Carriers That Support RCS Universal Profile

In November 2016, the RCS Universal Profile (Rich Communications Services) was introduced. The technology takes text messaging to the 21st century, emulating many of the features found in IM apps like WhatsApp and iMessage, but working through your phone number like regular SMS or MMS. The only thing is, your carrier needs to support RCS-UP to use the feature. Thankfully, the list is growing.

How To: Create Packets from Scratch with Scapy for Scanning & DoSing

By using almost any packet-crafting tool, a hacker can perform denial-of-service (DoS) attacks. With the power to create just about any packet with any characteristics, a hacker can easily find one that will take down a host or network. Nmap and Hping are effective packet manipulation tools, but there's also Scapy, which is almost infinitely customizable.

How To: Make Lazy Grilled Cheese Sandwiches in Your Toaster

The lengths people will go to for a grilled cheese sandwich are amazing. They'll use irons, wafflemakers, or whatever appliance that produces enough heat to produce the perfect combination of golden, grilled bread and oozy, melting cheese. I personally favor my cast-iron skillet or the oven for making a really great grilled cheese sandwich. If I'm feeling lazy, then a toaster oven will do. But what if you're at work or in a dorm and the break room only has a toaster?

How To: Writing 64-Bit Shellcode - Part 2 (Removing Null-Bytes)

Welcome to the sequel to the latest post on writing 64 bit shellcode! This tutorial will assume that you are aware of everything mentioned in the last one, as I will try to make this tutorial void of formalities and straight to the point! If you have not read the last one, I suggest doing so unless you are familiar with basic assembly programming and system calls. This is by no means rocket science, so therefore I will simply repeat my TL;DR from last time before we get started, so that the a...

Hack Like a Pro: Advanced Nmap for Reconnaissance

Welcome back, my novice hackers! Reconnaissance is one of the most important preparatory steps to hacking. As I have emphasized many times before here on Null Byte, you must know the operating system, the ports, the services, the applications, and sometimes even the language of the target to be effective. If you haven't taken the time to gather this info, then you are likely wasting your time.

How To: Build a Beginner Hacking Kit with the Raspberry Pi 3 Model B+

If you want to follow Null Byte tutorials and try out Kali Linux, the Raspberry Pi is a perfect way to start. In 2018, the Raspberry Pi 3 Model B+ was released featuring a better CPU, Wi-Fi, Bluetooth, and Ethernet built in. Our recommended Kali Pi kit for beginners learning ethical hacking on a budget runs the "Re4son" Kali kernel and includes a compatible wireless network adapter and a USB Rubber Ducky.

How To: The Ultimate Potato Cheat Sheet: Which Potato Goes Best with What?

I've been a fan of potatoes ever since I can remember... but mainly because they weren't a big part of my daily diet (which usually consisted of rice). And because my experience with potatoes was so limited, I only knew of two varieties growing up: big, brown Russets and sinewy sweet potatoes. As for cooking with potatoes—well, I'm embarrassed to admit that the only time I cooked potatoes when I was a kid was with the instant kind.

Cydia 101: How to Add Repos to Find More Jailbreak Tweaks

Unlike the iOS App Store, which is a one-stop shop that lets you search for and instantly download apps on your iPhone, jailbreak apps found within Cydia are far more fragmented and not as easy to source. In fact, Cydia only comes stock with a fraction of the apps and tweaks that are available on its official Apple counterpart. That's where Cydia repositories come in.

How To: Unlock the Bootloader on Your Pixel 4

The Pixel 4 is one of the most talked-about phones of 2019, and it has many things going for it, especially in the world of rooting and modding. Just as with previous Pixel generations, unlocking the bootloader is the gateway to realizing your device's true potential. It can make way for such things as TWRP, Magisk, custom ROMs, and many other device-specific mods just the same.
