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.
to stay secure, you dont just need Tor, and a VPN. You need good browsing habits. What are Browsing Habits You Ask?
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.
Hey there, reader! In this tutorial we are going to explain how values are stored in variables as either signed or unsigned. Try to not get lost!
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.
Hello there, reader! If you've clicked on this How-to then it means you are interested in learning some C programming or just generally curious about what this page has to offer. And so I welcome you warmly to the first of many C tutorials!
Greetings all. I'm back with another informational review of the diversity of utilities for use in the sphere of hacking at your disposal. Today we are going to cover the insides of CUPP (Common User Passwords Profiler) in its entirety. The tool is very basic in nature, as there is little to no configuration needed to get cracking (worst pun ever). So let's get started, shall we?
I see many people posting the same thing on the internet. "How do I become a hacker? Where do I commence?"
Hello, fellow grey hat hackers and aspiring coders. I'm back again with another python tutorial. Just that this one is gonna be a lot cooler ;-). We gonna make an encryption program, that well you know encrypts all the files on your pendrive or hdd or whatever you want....Also lots of thanks to DrapsTV. They have helped me a lot with Python and making awesome programs. The video is here:
Dropping upwards of $60 on a new game can really break the bank, and being a struggling college student leaves me having to decide whether to pick up the latest title or, you know, eat. But often my more primitive urges win out, meaning the only way to enjoy the latest and greatest games are vicariously, using increasingly-popular live streams.
When I tried to set up an eviltwin for a MitM-constelation in kali 2.0, I couldn't provide internet to the victim. The origin was the brctl bridging. I have read many tutorials but all of them where explained in backtrack and older versions of kali. So i was searching for a solution without using brctl and this solution will be explained now. This will just work on unencrypted wireless-environments.
First of all, I hope the title makes sense. :D Well, this is basically creating a program that can help with dictionary attacks. Generate possible passwords. It pretty much lies in you knowing the person you want to hack.
So, we all probably know that when you run a trojan made by Metasploit, nothing will appear to happen. This is a sign for me to immediately check my Task Manager, but for an unsuspecting victim, it will just seem like a broken file. It is likely that they will delete this "broken file" once they see that it "doesn't work." In order to prevent this, we need to disguise the trojan.
Before I start this tutorial, no, this is not that "Effective. Power." text that is going around. With that being said, let's talk about this attack.
What Is IPython? IPython is a richly featured replacement for the standard python interpreter. It offers a wider range of functionality, that the standard
Hello, hackers and engineers! Today we are going to dive a tiny bit deeper into the secrets of psychology, and how we can use them with hacking and social engineering attacks.
Have you ever fallen victim to a clever Jedi mind trick? Don't worry. It happens. There are evolutionary reasons as to why our brains sometimes give into the oldest tricks in the book. Fortunately, the more you understand the tricks of a salesman, the easier it is to avoid their gripping psychological influence. Clue #1: Too Much Specificity
Spiders are common pests that typically prefer to live outdoors. However, insects and warmth will eventually attract them into our houses. They like to spin their webs in corners, crevices and unused areas of your house. Most species are harmless and even act as a natural repellent for getting rid of other insects. However, in some cases, spiders can be very dangerous. Whichever the case may be, they are scary and people are always looking for natural ways to get rid of them.
Let's take a minute and talk about something you're doing wrong — using the restroom. Many view the subject as improper or even taboo, but why? Thanks to your upbringing, you've assumed you know the basics... But you don't. Avoiding discussion on the subject has led many of us to unwittingly interact incorrectly during our private time with our old friend, Jon.
Ever since the FBI took down the Silk Road and Dread Pirate Roberts last month, many questions have been raised about whether Tor still provides anonymity or not, and if it's now broken. I'll try to address that question here today succinctly from multiple angles, keeping it as simple and plain-language as possible. The Closing of Silk Road
Now that 3D display maker Looking Glass Factory is closing in on $2.2 million raised in its crowdfunding campaign for the consumer-grade Looking Glass Portrait device, the company now has a 3D content generator to go with it.
This week's Magic Leap Lumin OS update contained a number of goodies, including iris authentication, and a way to stream to Twitch from the device.
The latest immersive production from Magic Leap Studios finally got its debut on Monday at Siggraph, during which the company also released the app to the general public, so we took it for a spin.
Passwords on Windows are stored as hashes, and sometimes they can be tough to crack. In certain situations, though, we can get around that by using the hash as is, with no need to know the plaintext password. It's especially interesting if we can manage to get the hash of an administrative user since we can then authenticate with higher privileges by performing an attack known as pass the hash.
In the technology space, there are certain brands you grow to depend on. Whether it's due to a long, multi-decade track record of success, or new innovations that blow you away, some tech names accrue a rare kind of brand equity with users that's difficult to earn.
KeePassX, 1Password, and LastPass are effective against keyloggers, phishing, and database breaches, but passwords managers rely on the operating system's clipboard to securely move credentials from the password vault to the web browser. It's within these few seconds that an attacker can dump the clipboard contents and exfiltrate passwords.
While Microsoft dominated the augmented reality news at this year's Mobile World Congress, a small AR startup we've covered in the past arrived in Barcelona, Spain, to unveil the next phase of its mission.
The ability to execute system commands via a vulnerable web application makes command injection a fruitful attack vector for any hacker. But while this type of vulnerability is highly prized, it can often take quite a bit of time to probe through an entire application to find these flaws. Luckily, there is a useful tool called Commix that can automate this process for us.
Like many things associated with Magic Leap, the start of the company's first annual L.E.A.P. conference got off to a unique start. Taking the stage on Wednesday morning in Los Angeles, the company's CEO, Rony Abovitz, gave a brief introductory speech welcoming the crowd and outlining the mission of Magic Leap.
After the first image leaked of the upcoming successor to the Razer Phone, many were taken aback by its design, specifically how familiar it was. Last year's Razer already stood out with its boxy design and large bezels, and many thought the successor would change this. It didn't. But what if the reason for the familiar form factor is a project they teased earlier in the year?
With the new iPhones coming out, many see the current mobile market as just another epic battle between Samsung and Apple. But let's not forget there are many other phones that run Android. And when you start to sift through the specs, one stands out as a competitive alternative to the iPhone XR, the LG G7 ThinQ.
In most macOS hacks, a non-root terminal is used to create a backdoor into the device. A lot of damage can be done as a low-privileged user, but it has its limitations. Think twice before granting a file permission to execute — an attacker might be able to convert your harmless scripts into persistent root backdoors.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Earlier this month, when Apple announced at WWDC that iOS 12 would include an augmented reality tape measure called Measure, iPhone watchers seemed impressed by the new addition to the company's AR arsenal. Well, just a couple of weeks later, on June 19, it appears that Google remembered it had its own Measure app as well.
| Update: ZTE's issues with the US government have finally been resolved. Check out the details below.
After spending a good portion of 2017 teasing us with images and bits of news, Lenovo, in a partnership with Disney and Lucasfilm, has finally released its Mirage AR headset along with the Star Wars: Jedi Challenge game collection.
This is a very exciting time for mixed reality developers and fans alike. In 2017, we have seen a constant stream of new hardware and software releases hitting the virtual shelves. And while most of them have been in the form of developer kits, they bring with them hope and the potential promise of amazing things in the future.
This year, two new OEMs are trying to enter the crowded smartphone space. The first was Essential, and now Razer has entered the market with the Razer Phone. Utilizing the team they acquired from Nextbit in January, Razer has created a powerhouse of a device designed for gamers. Coincidentally, Razer announced their new device a day before Apple's biggest revision to the iPhone was released.
