Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see whether we can make it crash or overflow. This process is known as fuzzing. It is often the first step to developing an exploit, as we need to find some variable that is susceptible to overflowing.
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...
Welcome back, my neophyte hackers! I have already done a few tutorials on password cracking, including ones for Linux and Windows, WEP and WPA2, and even online passwords using THC Hydra. Now, I thought it might be worthwhile to begin a series on password cracking in general. Password cracking is both an art and a science, and I hope to show you the many ways and subtleties involved.

According to a study done by Kaspersky, 7.6% of Android users root their phones. That may not sound like a lot, but with over 2 billion Android devices out there, the math works out to over 150 million rooted phones — more than the total population of Russia, Mexico, or Japan — so root nation is an important demographic that deserves being catered to.
Canary tokens are customizable tracking links useful for learning about who is clicking on a link and where it's being shared. Thanks to the way many apps fetch a URL preview for links shared in private chats, canary tokens can even phone home when someone checks a private chat without clicking the link. Canary tokens come in several useful types and can be used even through URL shorteners.
If you want to get started sniffing Wi-Fi networks, you usually need to start with a wireless network adapter. But thanks to a Wi-Fi sniffing library written in Arduino and the ultra-cheap ESP8266 chip, you might not need one. For less than $10 in electronics, you can build a tiny Arduino Wi-Fi sniffer that saves Wireshark-compatible PCAP files and fits anywhere.

As a developer, before you can make augmented-reality robots that move around in the real world, controlled by a user's finger, you first need to learn how to harness the basics of designing AR software for a touchscreen interface.
Coinhive, a JavaScript cryptocurrency miner, was reportedly discovered on the BlackBerry Mobile website. It was placed there by hackers who exploited a vulnerability in the site's e-commerce software that allowed them to anonymously mine cryptocurrency every time the website was viewed. There's no doubt Coinhive, an innovative mining method, is being abused and exploited by hackers in the wild.
An attacker with shell access to a Linux server can manipulate, or perhaps even ruin, anything they have access to. While many more subtle attacks could provide significant value to a hacker, most attacks also leave traces. These traces, of course, can also be manipulated and avoided through methods such as shell scripting.
PowerShell Empire is a post-exploitation framework for computers and servers running Microsoft Windows, Windows Server operating systems, or both. In these tutorials, we will be exploring everything from how to install Powershell Empire to how to snoop around a target's computer without the antivirus software knowing about it. If we are lucky, we might even be able to obtain domain administrator credentials and own the whole network.
If I told you to follow as many users as you could possibly follow, in order to get more Instagram followers, that may seem counterintuitive, right? If I told you I'm trying to brainwash/annoy you with how many times I could possibly say versions of the word "follow" in an opening sentence, that would seem weird, too.
Text messaging is a core component of the mobile experience, and Google has added several AI-fueled features to help you text better, such as Smart Reply for quick response suggestions.

Posted below is an interesting video on the effects of low frequency square waveforms on cornstarch. To make, simply mix cornstarch and water, then place on a large speaker hooked up to an amplifier and a signal generator (generating around 20-30 hertz). An old stereo works great, as long as it has an aux-in. There is lots of free signal generating software at arms length, like this one. I found adding a little olive oil into the cornstarch mix makes it easier to handle, and contributes to th...
