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 back, my tenderfoot hackers! As hackers, we often are required to get past antivirus (AV) software or other security measures. To do so effectively, we need to have some understanding of how AV software works. In this tutorial, we will take a cursory view of how AV software works so that you can better strategize on how to evade detection by it.
If you've been to a farmer's market during tomato season, chances are you know that heirloom tomatoes are pricier (and funnier-looking) than their hybrid counterparts.
Although your friends might roll their eyes every time you talk about playing Clash of Clans, Call of Duty, or Candy Crush Saga, your excessive gaming habits might actually be making you healthier than everyone else.
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.
This is a simple pattern, designed to produce a well-fitting mitten. Both the right and left mittens worked the same up to the shaping for the top of the mitten. A slight adjustment for making one right and one left, then they are worked the same. The gusset for the thumb constructed with the increases made in the center of the gusset, rather than on each side. This makes it easy with a minimal amount of counting stitches as you go. I have been crocheting for 56 years. In doing research for w...
As the best-selling toy of all time, the odds of you once playing with a Rubik's Cube are pretty high. And if you're like me, or even the cube's inventor Erno Rubik, your first attempts likely ended in futility. Every twist, every turn, the cube just gets more and more mixed up. Is there really a solution?
I'm always looking for solutions to problems people are having with their smartphones. This means I spend a lot of time browsing forums and release sites looking for new apps. In doing so, I find a lot of apps that don't quite solve a major problem, but are nonetheless pretty cool. I came across four of those this week.
It's a common misconception that iPhones are impervious to cyberattacks and "more secure" than Android. And when an iPhone does get hacked, it's nearly impossible to tell that it happened.
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. The main goal of a pentest is to identify security holes and weaknesses so that the organization being tested can fix any potential issues. In a professional penetration test, there are six phases you should know.
When it comes to sniffing Wi-Fi, Wireshark is cross-platform and capable of capturing vast amounts of data. Making sense of that data is another task entirely. That's where Jupyter Notebook comes in. It can help analyze Wi-Fi packets and determine which networks a particular phone has connected to before, giving us insight into the identity of the owner.
The wait wasn't so long this time. Apple released public beta 3 for iOS 13 on Thursday, July 18, just one day after the release of developer beta 4. For context, Apple took five days to seed public beta 2 after releasing dev beta 3, so it's a pleasant surprise that the latest public beta dropped so soon.
We're pumped for iOS 13 and all of the fresh features and changes that come with it. Developer beta 3 came with new features in the double digits, including AR eye contact in FaceTime and mouse cursor size customization. Developer beta 4, released today, has a few more additions and changes as well.
The third developer beta for iOS 13 has been out since July 3, and while devs have had fun exploring all the new features, those of us on the public beta have sat on the sidelines running the public version of dev beta 2. But we don't need to wait any longer, as Apple just released iOS 13 public beta 2 and all the goodies that come with it.
On July 3, Apple pushed out iOS 13 developer beta 3 for iPhone, and there's a lot found hidden within. A new FaceTime setting, more Arcade details, full-page scrolling screenshots everywhere, a noise cancellation option in the Control Center, and a new markup tool — and that's just a few of the new features.
There's no doubt iOS 13 has dominated the talk around the Apple community this month. Since the announcement and release of the first developer beta, we iPhone users have had a treasure trove of new features and changes to explore and discuss. Now the fun continues with iOS 13 dev beta 2. Who's ready to start up the conversation all over again?
The first developer beta for iOS 13 is available to install on iPhone models, but the process for doing so may be a bumpy ride. Apple has not included configuration profiles for the developer beta yet, and many developers are having issues installing iOS 13 even with macOS 10.15 Catalina installed. Plus, since this is the first beta, there are a lot of problems with old and new features to work the kinks out of.
Open-source intelligence researchers and hackers alike love social media for reconnaissance. Websites like Twitter offer vast, searchable databases updated in real time by millions of users, but it can be incredibly time-consuming to sift through manually. Thankfully, tools like Twint can crawl through years of Twitter data to dig up any information with a single terminal command.
I noticed the neon yellow sign at the new location of Pho Bar in Chinatown right away. The sweeping cursive yellow letters spell out "Crazy Rich Broth"; the same phrase printed on the back of servers' shirts. It's the kind of minimalist but colorful design feature that is especially popular on Instagram at the moment — shots of patrons in front of a glowing sign.
Many popular IoT devices have terrible security. For instance, a hacker who's on the same Wi-Fi network as a Sonos speaker can assume direct control over the device's behavior. If an IoT device doesn't secure the messages used to control it over a network, it's easy for somebody to write a few Python scripts to make it do whatever they want.
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. It's easily the best custom kernel out there, and the reason for that is its awesome developer, flar2, aka Aaron Segaert.
Influencers of augmented reality demonstrate expertise in their fields and outline a strong vision for the future that they evangelize to others. They help define the direction of the industry and identify others who foster and create innovation in the field.
It only takes a few commands to manipulate a MacBook's secure HTTPS traffic and pluck login passwords out of the encrypted data. Let's take Facebook and Gmail hacking to the next level by intercepting Safari and Google Chrome web traffic in real time.
If you're on the hunt for a profitable side-gig, or even a completely new way to to make money, you'll want to take a look at Upwork, a leading freelancing platform that connects skilled freelancers with clients from all over the world.
In our last ARKit tutorial, we learned how to measure the sizes of horizontal planes. It was a helpful entryway into the arena of determining spatial relationships with real world spaces versus virtual objects and experiences.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
If you want to follow Null Byte tutorials and try out Kali Linux, the Raspberry Pi is a perfect way to start. In 2018, the Raspberry Pi 3 Model B+ was released featuring a better CPU, Wi-Fi, Bluetooth, and Ethernet built in. Our recommended Kali Pi kit for beginners learning ethical hacking on a budget runs the "Re4son" Kali kernel and includes a compatible wireless network adapter and a USB Rubber Ducky.
A powered-off Windows 10 laptop can be compromised in less than three minutes. With just a few keystrokes, it's possible for a hacker to remove all antivirus software, create a backdoor, and capture webcam images and passwords, among other highly sensitive personal data.
They're finally here — Samsung has officially revealed the Galaxy S9 and S9+, which run Android Oreo out of the box. Since we've spent plenty of time with the Oreo beta for the Galaxy S8, we already know about some of the best new software features coming to the Galaxy S9. Like previous updates, Samsung has enhanced its software with a fresh look and brand new functionality.
While autonomous vehicles are almost assuredly the future of personal transportation, we are likely many years from seeing self-driving cars become as ubiquitous as manually-driven ones, as the auto industry has a myriad of government regulations and other constraints to contend with. Until then, augmented reality is looking like the next big thing in automotive technology.
There's no doubt Kali has established itself as the most popular penetration distribution available. However, just because it's the fan favorite of beginners and security researchers doesn't make it right for everyone. Manjaro Linux is a beginner-friendly Arch-based distribution which can be easily weaponized with the Black Arch expansion, creating a friendlier first-time Arch experience.
For all those times when an app either isn't available or simply won't cut it, your phone's internet browser provides access to your favorite websites and services. But some browsers are flat-out better than others, and chances are, the browser that came pre-installed on your phone isn't the best option out there.
Word games can expand your vocabulary skills in all sorts of exciting and creative ways. Because of this, both the iOS App Store and the Google Play Store are awash with word games, making it hard to differentiate between good and bad titles. This is especially troublesome if you're looking to purchase a game, as everyone hates to waste hard-earned cash.
Samsung has finally rolled out the Android Oreo update for the Galaxy S8 and S8+. If you're just now getting the update, you'll be happy to know that your Galaxy just got upgraded with plenty of cool new features. Like previous updates, Samsung has improved upon its software by including a new look and new functionality.
While hackers adore the command line, working with the GUI (graphical user interface) of an operating system has some advantages. This is especially true when it comes to post-exploitation. When we can control the mouse and keyboard of a remote computer, we can truly say we have complete control over the device. Today, I'm going to introduce to you the PyAutoGUI module, which does just that, and just how much fun you can have with it!
NOTICE: Ciuffy will be answering questions related to my articles on my behalf as I am very busy. Hope You Have Fun !!!
Cryptography is the science of keeping secrets, or more specifically, the science of disguising them. As a point of fact, cryptography has progressed quite a bit farther and now encompasses file and message integrity, sender authentication, and pseudo-random number generators.
As I said in this earlier post, there's no easy way to explain or define the Steampunk aesthetic. There are a large number of Steampunk tropes or "cues", as I call them, that bring to mind the feeling of Steampunk. These cues combine to push past the "not-Steampunk" threshold into firmly "Steampunk" territory.
There are a lot of cool shortcuts you could run on your iPhone, but in iOS 13 and iOS 14, you'll likely see a notification any time you try to run an automation. Shortcuts should feel seamless when their actions are performed, and getting a banner alert each time one initializes takes away the seamlessness of it all. But there is a way to block them.
Smartphones are inherently bad for privacy. You've basically got a tracking device in your pocket, pinging off cell towers and locking onto GPS satellites. All the while, tracking cookies, advertising IDs, and usage stats follow you around the internet.
