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...
In this simple tutorial you will be shown step-by-step how to write local shellcode for use on 64-Bit Linux systems. Shellcode is simple code, usually written in assembly that is used as payload in exploits such as buffer overflow attacks. Payloads are the arrow head of an exploit: though the rest of the arrow is important for the delivery of the attack, the arrow head deals the killing blow. In reality, payloads are slightly less exciting yet far more interesting and intelligent than medieva...
Everyone has the same five spirits in their bar: vodka, rum, whiskey, tequila, and gin. They're all great, but every so often the mood strikes to try a cocktail with a little something different. We'd like you to meet three spirits from South America that would make a welcome addition to your next cocktail party.
Welcome back, my rookie hackers! As hackers, we are often faced with the hurdle of cryptography and encryption. In some cases, we use it to hide our actions and messages. Many applications and protocols use encryption to maintain confidentiality and integrity of data. To be able to crack passwords and encrypted protocols such as SSL and wireless, you need to at least be familiar with the concepts and terminology of cryptography and encryption.
Any beer aficionado who's been to Ireland will always talk about how the Guinness there "just tastes different." But save your eye rolls, skeptics: it turns out your favorite lagerhead actually has a valid point.
If you're a sushi lover but not an expert sushi maker, you can still enjoy the flavors of sushi rolls at home with these deconstructed sushi dishes.
A landmark bill finally went into action this week that will allow American cellular customers to unlock their smartphones for free. The process of unlocking may vary between mobile service providers, but you can rest assured that you are now entitled, by law, to carrier-unlock your smartphone.
There are many ways to take a screenshot in macOS (previously Mac OS X), but all of the well-known options give you a drop shadow in the picture when snapping application windows.
Somehow, we end up with a pile of leftover candy canes at the end of every December. Yet just because the enthusiastic holiday commercials are gone and the Christmas cards are on discount doesn't mean you have to let the minty sweets go to waste.
Welcome back, my nascent hackers! We have spent a lot of time in previous tutorials focused on hacking the ubiquitous Windows systems, but the vast majority of "heavy iron" around the world are Linux or Unix systems. Linux and Unix dominate the world of Internet web servers with over 60% of the market. In addition, Linux and Unix servers are the operating system of choice for major international corporations (including almost all the major banks) throughout the world.
Emojis have transformed the way we laugh and cry, tell stories, give responses, and express excitement to get a drink after work — without any actual text required. Heck, in an incredibly meta move, the Oxford Dictionary even named the "Face with Tears of Joy" emoji as their word of the year at one point. So how could you not want to be an emoji character for Halloween? Emojis are everywhere. The ubiquitous symbols are already on smartphones, tablets, and social networks, so why not help them...
Most Android devices allow you to simply replace a ZIP file in your /system/media folder if you want to change your boot animation. Unfortunately, though, this isn't the case for the Galaxy S5, as it's been buried deep in Samsung's TouchWiz skin.
Osteoarthritis can affect every gender and at any age but it commonly occurs in women than in men. In America there are approximately 27 million Americans aged over 25 who live with osteoarthritis.
I'll give Samsung credit where it's due—the stock keyboard on the Galaxy S5 is actually pretty nice. There's a dedicated number row that resides at the top (something that the Google Keyboard needs a hack to achieve), and various settings exist to make switching between languages a breeze.
Who doesn't enjoy sitting down to a nice dinner with a cocktail in hand? After a long day, a drink is a great way to unwind. Yet your favorite spirits can do more than just help you relax after work. By utilizing alcohol in the kitchen, you can enhance everything from how food tastes to your health.
Recently, Sprint announced a partnership with Harman Kardon to deliver exclusive sound FX technology to their variant of the HTC One M8. The joint effort between the two companies is both to entice customers to switch to Sprint as well as improve the overall audio quality coming from the already extraordinary BoomSound speakers. But while this is great for new and existing Sprint customers, it does leave the rest of us out in the cold.
Welcome back, my hacker noviates! In a recent post, I introduced you to Shodan, the world's most dangerous search engine. Shodan crawls the globe from IP to IP address, attempting to pull the banners of each web-enabled device and server it finds.
After much hype and even more leaks, the HTC One M8 has finally been unveiled at the company's New York release announcement.
While we've already covered several good ways to tame the itch of a mosquito bite, you're much better off preventing them from biting in the first place than dealing with the itchy aftermath.
About ten years ago, Western research figured out that green tea was a nutritional powerhouse. After all, in Asian countries where green tea is consumed throughout the day, cancer rates tend to be much lower, although there are probably other factors contributing to that fact, like less processed food and red meat in the standard Asian diet.
February may be the shortest month of the year, but for iOS softModders, there were plenty of apps and tweaks to fill up those days. Whether patching major security holes or just a tweak to make speed dialing more efficient, there was a plethora of great mods for our jailbroken iOS 7 devices. These are our favorites from the month.
Welcome back, my greenhorn hackers! After the disaster that was Windows Vista and the limited and reluctant adoption of Windows 8 and 8.1, Windows 7 has become the de facto standard operating system on the desktop/client.
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.
Welcome back, my hacker apprentices! I recently began a new series on digital forensics to show aspiring hackers what the forensic investigator can do and see while investigating a cyber attack. This is the second installment in that series and will focus upon network forensics. In other words, what can a network forensic investigator learn about the attacker during an investigation and how.
Automation applications bring the future a little closer. If you've seen Minority Report or other futuristic sci-fi movies, the intrigue of having your electronics work independently is something we can all appreciate.
Welcome back, my tenderfoot hackers! So many readers in the Null Byte community have been asking me questions about evading detection and hacking undetected that I decided to start a new series on digital forensics.
The newest Android operating system, Android 4.4 KitKat, has been unleashed with the arrival of the Nexus 5, and soon to be rolled out to other Nexus devices and Google Play Edition smartphones any day now. Only problem is, the Samsung Galaxy S3 isn't getting 4.4 for a very long time. It doesn't even have 4.3 Jelly Bean yet.
When life gets boring, you change it up. A little tweak in your schedule goes a long way in making your existence fresh again, and it could be anything from putting on deodorant to seeing a movie with someone you don't know. The more flexible you are in life, the more dynamic it should be.
When it comes to the user interface, you're pretty much limited to the stock one that comes on your Samsung Galaxy Gear smartwatch—a carousel of large black and white icons representing the features and applications on the watch.
No matter what the clean freaks out there try to tell me, I still drink my Los Angeles tap water without a care in the world. I figure that I've already consumed much more heinous things in my lifetime. Street vendor "steak" burritos comes to mind.
I love surprises. Surprise parties, surprise visits, surprise Patrick... But there are times when a surprise is the last thing you want, like reaching into your pocket to find that your Samsung Galaxy S3 is not where it should be.
Everyone hates to feel like they've been taken advantage of, especially when buying a used vehicle. The thought comes across every car buyer's mind... "Did I just get taken by that smooth-talking salesman?" When it comes to cars, how do you know if you're really getting a good deal, or if you're being offered a fair price for your car? After all, cars are most peoples second largest investment, so we need to make this decision wisely.
Welcome back, my fledgling hackers! If you're like most aspiring hackers, at one time or another you've probably spent too much time playing Call of Duty and not enough time preparing for your final exams.
While the PlayStation 3 is an awesome gaming console and the iPhone is an awesome smartphone, Apple and Sony have made two devices (that could be perfect for each other) nearly incompatible. Truth be told, this is more Apple's fault than Sony's, but we'll get into that later.
There are hundreds of keyboard shortcuts out there, but these 7 are the ones you'll definitely want to remember. I use them every day, and you should too. Step 1: Tab Domination
You know what ladies love? A man who can handle his tools. What do the ladies love even more? A man who can say checkmate. Well, except maybe this lady.
One of the best aspects of Android is its customization options. You can change launchers and icons, add widgets, and replace standard apps with others that allow full customization. Android allows your device to really take on your personality, from the inside and out.
PRL, or Preferred Roaming List, basically tells your phone which towers to connect to first. Changing PRLs can improve reception and data speeds, and in some cases even give you access to corporate/test towers.
Not that long ago I wrote an article discussing what it would be like, realistically, if you were to accidentally travel back in time to the Victorian era. At the end of that article, I mentioned that the best thing you could bring with you on a time-traveling adventure is a Kindle, or similar e-reader, stuffed full of the knowledge of the 21st century. Why a Kindle? Well, I own a Kindle, and I love it. However, there's far more to it than that.
Many social networks have become a part of our daily routine. Checking Facebook or sending out a Tweet are things millions of people do every single day. So, one would think that having a great app offering for Windows 8 would be a no-brainer. But, and this is a huge but, there are still no official Twitter or Facebook apps for Windows 8.
