How To: What Do All Those 5G Status Icons Mean on Your iPhone 12, 12 Mini, 12 Pro, or 12 Pro Max?

If you upgrade to an iPhone 12, 12 mini, 12 Pro, or 12 Pro Max, you can take advantage of super-fast 5G speeds, but which 5G network are you actually getting and is it better than the others? Depending on your carrier, you may see 5G, 5G+, 5G UW, or 5G E in the status bar next to the signal strength, and there's a pretty big difference between them.

How To: Auto-Change Your iPhone's Background with MacOS Big Sur's Dynamic Wallpapers

Three new wallpapers showed up in iOS 14.0, each with dark and light versions, while iOS 14.2 added eight more. Each iPhone also has live wallpapers catered specifically for it. However, none of Apple's wallpapers are dynamic. That means they won't change automatically based on certain conditions, such as what time of day it is. MacOS's do, though, and you can get those working on your iPhone.

How To: Change a Phone's Coordinates by Spoofing Wi-Fi Geolocation Hotspots

In many urban areas, GPS doesn't work well. Buildings reflect GPS signals on themselves to create a confusing mess for phones to sort out. As a result, most modern devices determine their location using a blend of techniques, including nearby Wi-Fi networks. By using SkyLift to create fake networks known to be in other areas, we can manipulate where a device thinks it is with an ESP8266 microcontroller.

Green Tea: It Cleans More Than Just Your Body

About ten years ago, Western research figured out that green tea was a nutritional powerhouse. After all, in Asian countries where green tea is consumed throughout the day, cancer rates tend to be much lower, although there are probably other factors contributing to that fact, like less processed food and red meat in the standard Asian diet.

How To: Permanently Delete Text Messages on Your iPhone

Deleting text messages on your iPhone may seem like a pretty simple task, but it's those really simple tasks that usually end up causing headaches later on. Data can stick around, even if you asked it not to, so there's always a slight chance that embarrassing and incriminating texts you supposedly deleted may end up in the wrong hands one day.

How To: Program MicroPython NeoPixel Holiday Lights to Animate However You Want

Individually addressable LEDs, also commonly called "NeoPixels" after the popular Adafruit product, are a bright and colorful way to get started with basic Python programming. With an inexpensive ESP8266 or ESP32 microcontroller, it's easy to get started programming your own holiday lighting animations on a string of NeoPixels with beginner-friendly MicroPython!

How To: Detect & Classify Wi-Fi Jamming Packets with the NodeMCU

The most common Wi-Fi jamming attacks leverage deauthentication and disassociation packets to attack networks. This allows a low-cost ESP8266-based device programmed in Arduino to detect and classify Wi-Fi denial-of-service attacks by lighting a different color LED for each type of packet. The pattern of these colors can also allow us to fingerprint the tool being used to attack the network.

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.
