It has been a long while since I last came here to write an article. Graduate school keeps you busy. After I looked over what I had written previously, I decided that I should introduce another fun topic from cryptography. In this case, steganography.
The world of Lego is timeless primarily because everyone, regardless of age or background, can build a wide variety of amazing things with the simple component blocks from the classic toymaker.
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
If you're using a mobile device, it's a pretty safe bet that your apps are sending lots of information back and forth from their servers.

Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
A PirateBox creates a network that allows users to communicate wirelessly, connecting smartphones and laptops even when surrounding infrastructure has been disabled on purpose or destroyed in a disaster. Using a Raspberry Pi, we will make a wireless offline server that hosts files and a chat room as an educational database, a discreet local chat room, or a dead-drop file server.
In the aftermath of the unindicted police killings of Michael Brown and Eric Garner, we've been told that the system worked as intended. When our legal system's outcome is at conflict with what a majority of Americans believe is just, it's clear that some changes are needed. But what specifically needs to change? And what can an average citizen with a moral and just cause do to prevent these kinds of tragedies from repeating themselves again and again?
Like theme music, I always feel that I need more fog in my life. Fog can be useful for many reasons—warding off smaller siblings from your bedroom, keeping curious hands out of your cupboard, and tricking your friends into thinking there's something horribly wrong with their vehicle. So, today we'll be making a very simple fog machine for small scale applications.
Apple's iMessage is one of the main reasons to use an iPhone, and there's a lot you can do in chats without being overly complicated.

Penetration testing, or pentesting, is the process of probing a network or system by simulating an attack, which is used to find vulnerabilities that could be exploited by a malicious actor.

In a professional penetration test, there are six phases you should know.

You can mod every aspect of your phone's software with root, but if you want to make changes at the hardware level, you'll need a custom kernel. If you've looked into custom kernels before, one name undoubtedly kept coming up: ElementalX.

Many lazy cooks skip rinsing off their grains before they cook 'em, but that's a big mistake for a few reasons. Some grains have coatings on them that need to be rinsed off to cook properly and taste good.

In less than a month, WWDC, Apple's Worldwide Developers Conference, will reveal the company's plans for the upcoming iOS 18 and iPadOS 18 software updates.
