The Touch ID fingerprint scanner on the iPhone 5S was one of the phone's biggest selling points. Now, the Touch ID system can do more than just unlock your phone, like pay for stuff, and is even present on the new iPads (as well as iPhone 6 models, of course).
What's up, peeps? In this quick tutorial, we will be looking at structs, a special kind of data type.
Before we begin learning about another vulnerability, we are going to explore printf in a bit more detail. This will be quick little tutorial.
In many programs on Linux, you'll come across programs which allow you to specify additional arguments instead of just simply running the program by itself. If you've used the Kali distribution, I'm more than certain you'll have come across these with the command line tools, else if you have been following these tutorials, we have already come across three tools which also use the same technique, i.e. gcc, gdb and wc. How do we do this with C? Let's find out.
Hey readers! This tutorial will be the entry point for the introduction of buffer overflows. Something like requesting user input is a very common place for vulnerabilities to pop up and we will definitely have fun while trying to make programs crash. But for now, let's start with how we can get input from a user.
What's up guys! It's time to discuss strings in more detail. Review
If you're tired of your roommate stealing your Cheetos out of the pantry or simply want to indulge in something creepy, then keep reading. With the iPhone 5 finally released, many people will soon be selling or giving away their older iPhones. But should they? Instead of ditching your old iPhone, why not use it to engage in some Big Brother type espionage? There are some really awesome ways to use your old iPhone, but spying on people is definitely the most bang for your buck. First, you'll w...
Apple does not provide a native way to lock apps on your iPhone behind Face ID, Touch ID, or your passcode. For a long time, we've wanted that option for improved privacy and security, but Apple does allow developers to use its authentication protocols. Apps like Messenger, Outlook, and WhatsApp give the option to lock them down, but for the apps that don't, you can force it with a little time and effort.
In the US, law enforcement officials can make you unlock your smartphone with a fingerprint, but they can't force you to input a password or PIN, which would violate your Fifth Amendment rights. To help you from ever being in a scenario where you're forced to put your finger on the Touch ID sensor, Apple has a built-in way for you to disable biometrics on your locked or unlocked iPhone in mere seconds.
Hello again, and welcome back to another tutorial on functions, this time, covering recursion. What Is Recursion?
Hello readers, in this tutorial, we will be discussing how to perform file operations such as reading and writing.
What's up readers? We have ever so slightly touched upon this concept of scope with variables but still don't really know what it means. In this tutorial we will learn the behaviors of variables existing in our programs and within functions.
In the last tutorial, we learned how to make functions and how they work on the high level. This time, we will take a peek under the hood again, stare deep into its soul and see its ugliness face to face to see how it works in the lower level.
Hello again! In this tutorial, we are going to go over something called "operators" which will help us build upon conditions of control structures and also some variable manipulation. Without further ado, let's dive in!
Welcome back to another C tutorial, this post covering the first part of control structures, if statements. Let's get right into it.
How is it goin', fellow 1337 haXX0rZ! dtm here with another article, this time, we'll be looking at infecting PE files, executables in particular for this write-up. Obviously some prerequisite knowledge will be needed since this isn't really newbie-friendly. If you are still a beginner, fear not, it might still be interesting to read! Hopefully!
If you use a wireless mouse or keyboard, you could be leaving yourself open to attacks from hackers. Researchers at Bastille had discovered in January 2016 that attackers could make use of a cheap $15 antenna to sneak into your computer through a wireless mouse or keyboard dongle (receiver).
Hello again, readers! In our previous crypter tutorial, we looked at how we could obfuscate our malware (or any program) by using a simple one-byte XOR key. In this quick tutorial, we will be looking at how a simple little tweak can create a better means of obfuscation. Let's get right into it!
Welcome to a tutorial on XOR encryption. We'll be looking at what XOR is and how we can use it to encrypt or decrypt data.
Hello there! This will probably be the final tutorial on functions where we will be looking over a method called pass by reference. This technique allows us to modify large amounts of data without the overhead and return multiple values. Let's go!
Welcome back to a tutorial on malware. We'll be discovering a method to beef up our little trooper. Without further ado, let's jump right in!
Welcome to an introduction on writing basic malware, an optional sub-series in which I expose you to malware and its technologies. This is written for those who wish to seek a beginning in malware analysis or enlightenment on the subject. We will be justifying the writing and covering types of malware.
In previous tutorials we have encountered these things called pointers and addresses but we still don't know what they really are. Let's learn a bit more to clear things up.
Welcome back to another tutorial on functions. Last time, we looked inside memory to see what functions looked like in the flesh and all that Assembly was pretty nasty. At least you have some exposure to it. This time, we will be examining how functions work with the stack.
Welcome to another C tutorial. We will be looking at arrays, discussing what they are, when they are used and their special relationship with the char variable. Let's begin.
Hello again, reader! In this post, we are going to cover some data types and how to declare variables. It shouldn't be too hard so just sit back, relax, grab some popcorn and enjoy the ride (while you still can!).
Welcome back, reader! In this tutorial, we will be covering our first program! So let's get to it. We all know the unspoken tradition of the first program when learning a language and of course, here we will respect and complete it. Fire up your favorite text editor (be it vim, emacs, gedit, it's all the same to me, no h8) and try to keep up.
Your sensitive personal data should be strongly protected, and it's never more vulnerable than when you are online. The internet connection is a prime avenue of exposure, and email is one of the least secure forms of communication. Fortunately, there is an easy solution to both of those problems.
Hey guys, in this tutorial, we are going to learn about the heap segment and how to use it for storing data in our programs. We will also go into the details of its use in conjunction with the char pointer and struct data types.
What's up readers? Today I'll be introducing to you a new vulnerability called the Format String vulnerability (in case you missed the title). It won't be much, just a little motivation to keep you guys going. A little teaser, if you may.
Welcome to a tutorial explaining functions. This article will help clarify some things we have already been exposed to such as function prototypes, function calls, return values, etc.
Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...
With all of the hype around the new iPhone 13 series and new iPad and iPad mini unveiled this week, it would be easy to overlook a very critical update for the device you already have in your pocket.
While there isn't as much personal data residing on your Apple Watch as there is on your iPhone, it's still a good idea to set a passcode for it and lock it up when you're not using it. If you don't, while it's charging or otherwise off your wrist, others may be able to sneak a peek at your activity, messages, emails, and other personal details. Plus, you won't be able to use Apple Pay without one.
Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...
Welcome to a tutorial on crypting technology. In this article, we will be discussing types of crypters, how they work and why they work. After defining these, we will then make our own basic crypter using the function I gave to you as a task to complete by yourself in the previous tutorial.
Welcome finally, to a tutorial on buffer overflows! At last we have reached an exciting part of this series where I will dedicate the entire article on explaining and exploiting the notorious vulnerability. Grab some popcorn, sit back and enjoy the show.

There's nothing more tedious, yet exciting, than watching surveillance cameras at work. They prey on the innocent and the unknowing. They protect businesses, workplaces, and homes. They catch criminals in the act, find hilarious anomalies, and are just darn cool when you're not the one that's supposed to be eavesdropping with them.
Kipkay has developed a shoplifting prank, and all you need is a little electromagnetic strip to play this prank at Walmart (or wherever). You also need to bring a magnet. You swipe the strip thirty times with the magnet and this will actually magnetize the strip. Use this as inspiration for one of your April Fools Day pranks!
