Zanti: Introduction

I've been doing tutorials on Rasberry Pi and I would like to thank everyone that have both read the tutorials and gave me feedback on how well I'm doing. But now I've decided to take a small break and start a mini series that I'm hoping to be at least five tutorials. This doesn't mean I'm gonna stop posting Raspberry Pi tutorials, but since I'm learning so much at the same time I've decided to share some of that knowledge. Hence this tutorial. Please sit back, relax and read on.

Android Basics: A Series of Tutorials for Beginners

All across the web, you'll find guides on setting up various apps and mods for your Android device—but while these are certainly useful, they all seem to be working under the assumption that the reader has a certain level of knowledge about Android. For someone that's just getting started with the world's most popular mobile operating system, the basics of Android simply aren't covered as well as they should be.

How to Meterpreter: Obtaining User Credentials with PowerShell

In this article I will show you how to obtain victim's credentials without cracking any hashes. There are a couple of ways to perform this task (for example dumping the SAM file and cracking the NTLM hashes), but here I will explain how to do it using PowerShell and a bit of social engineering. We are going to create a fake login popup.

How To: Security-Oriented C Tutorial 0x0B - User Input

I'm very excited to launch this project. So, let's start by explaining what it is...

How To: Hack WPA/WPA2-Enterprise Part 2

In the second part of this tutorial, we are going to crack the hashes that we've captured previously. I'm going to explain how to do it with the powerful John the Ripper. It comes with Kali by default, so no need to install!

News: Social Engineering for the hell of it.

I've recently been on holiday in Europe, staying in a hotel that was part of a big chain that included many in the local area. A quick review of the wi-fi within range of my room showed that there was another in the chain that was in range of my Yagi Turbotenna, which naturally got me thinking. If I wanted an anonymous internet connection, this could be quite handy.

How To: Last All Day Long in Uncomfortable Shoes

We've all been there: slipping on a pair of perfect yet slightly uncomfortable shoes, hoping they'll stretch to fit perfectly. After about 30 minutes of wear, suddenly those fantastic shoes aren't feeling very great. By the end of the day, your poor feet are covered in throbbing blisters.

How To: Find the Location of Any IP with PyGeo IP Locator(GUI for GeoIP/Pygeoip)

Based on OTW's encouragement in his post on "How to Find the Exact Location of Any IP Address", I decided to make a gui(graphical user interface) which would hopefully make the process easier. However, because turning a python script into a standalone executable is a right pain in the nether-regions, particularly for linux, I haven't yet completed this step(I will soon and update this). I did however, make an apk for android(you use a .apk file to install an app on your android device), which...

How To: Improve Your Memory by Daydreaming

When you're trapped at your desk before a jumble of data just waiting to be categorized, or zoning out during an important meeting, your mind wanders and, chances are, you feel a little guilty because of it. Yet you shouldn't try to reign in that distracted thinking. Instead, let your brain get distracted, and you'll unconsciously strengthen your memory.

Weird Ingredient Wednesday: Durian Stinks Like Hell but Tastes Heavenly

I've known eaters who will fearlessly bite into the hottest peppers, but even they have quailed before durian, the fruit that hails from Southeast Asia and whose smell has been compared to garbage, rotting flesh, and the bathroom post-use. However, this hefty globe with its spiny, prickly outer covering isn't called "the king of fruits" for nothing. According to its many fans, its stench does not correlate to its taste, which has been described in extremely flattering terms. Monica Tan of The...
