Although there has been much speculation about how much damage could be done if hackers were to take control of a country's SCADA systems, there have been few examples - until a few months ago, with the power outage in Ukraine caused by hackers.
If you want to keep your online world secure, your best bet is to have a different password for every site and service that you use, and to make sure each of the passwords are comprised of random characters instead of familiar words or numbers. But this obviously creates a problem—how exactly are we supposed to remember all of these complicated passwords?
In this article, we will explore the basics of radare2, a powerful package that comes with Kali. We are going to write a simple program, and then disassemble it, to see what is really doing in the processor.
In part one of this tutorial we found out that your English teacher is a paedophile, by using a Man in the Middle attack to intercept his internet traffic.
Piracy, it can be argued, is the scourge of the internet. But when it comes to music, sometimes it's best to give a listen to a track or album before deciding to spend your hard-earned money on fully supporting it.
Social Engineering was mentioned a few times here on Null Byte, but not very many explained what it is, or how to do it. I love this quote because it's true: Social Engineering is the key to carrying out client side attacks, and all you need is a little creativity!
My reliance on autocorrect has made me a horrible speller. I take it for granted that it'll catch all my mistakes, but it only ends up making matters worse (especially when it inadvertently makes correct words wrong). So instead of relying on autocorrect to fix typos, why not try to completely prevent mistakes from happening in the first place?
Welcome back, my neophyte hackers! In previous tutorials, we learned how to steal system tokens that we could use to access resources, how to use hashdump to pull password hashes from a local system, and how to grab password hashes from a local system and crack them.
Location Services, a native feature on iPhones since iOS 6, is used to pinpoint your approximate location using a combination of GPS, Bluetooth, Wi-Fi, and cell tower information. Apple uses this on their smartphones for many useful reasons: so that you can tag locations in Instagram, get better directions in Maps, and check for matches based on your location in Tinder.
Does your Samsung Galaxy Note 3 feel slower than it used to? Background processes, cached files, malicious applications, and buggy updates can all lead to a sluggish smartphone. It's just what happens over time.
When you buy a Mac, you accept that you're giving up the customization found on Windows or Linux systems for a more fluid and secure machine. This is great for most consumers, but for those of us who'd rather opt for a tailor-made experience, there are always developers that can combine functionality with stability.
With all of the different websites we use in our day-to-day lives, keeping track of our numerous login credentials can start to become a hassle. This has created a market for password managers that aim to centralize these account credentials and generally streamline the process of logging into our favorite sites.
Welcome back, my hacker novitiates! When we are trying to find vulnerabilities in a website to attack, we need a solid web server vulnerability scanner. Internet-facing web apps can open enormous opportunities for us as they are often riven with vulnerabilities and can often offer an entire point to the internal network and resources.
3D has been all the rage for the past few years. It seems like every other film has a 3D aspect to it, our TVs have 3D capabilities, and we can even print functional objects using increasingly affordable 3D printers. And after some trial and error (ahem, Evo 3D), it's finally taking shape on mobiles.
Google recently updated the camera software for the Nexus 5, and in doing so, made the app available to all devices running Android KitKat. This means that not only do we get a nice new camera interface on our phones, but we also get the benefit of an expanded development community.
The international hit Xperia Z2 may be headed to Verizon if a posted, and quickly erased, image is any indication. Take this information with a grain of salt—I certainly am—but this could be Sony's entrance into the non-GSM realm. The image above was posted to Sony's Xperia Google+ page, and very quickly removed. Compared to the Z2 that's currently on the international market (below), we can see that not only has the Sony logo shifted to the bottom, but a Verizon logo rests squarely along the...
Sometimes you need more than just your brain to split the bill at a restaurant or to calculate how much your cable company is ripping you off.
Welcome back, my hacker apprentices! Several of you have written asking me how you can check on whether your boyfriend, girlfriend, or spouse is cheating on you, so I dedicate this tutorial to all of you with doubts about the fidelity of your spouse, girlfriend, or boyfriend.
So, you've got a brand new PlayStation 4, but unfortunately, you've got "No Signal" now, too. You can't really game or watch movies on your new toy if you can't even bring up the PlayStation menu on your TV screen.
The closest I've ever been to first class was when I was a young kid running up and down the aisles on a long international flight. I remember being in awe of how big the seats were and how much food was available. Ever since that moment, I've made it my life goal to earn enough money to make first-class flights a regular occasion.
YouTube is the third most popular website in the world, after Google and Facebook. Millions of subscriptions happen each day on YouTube, with over 800 million unique users visiting each month. In that timespan, roughly 4 billion hours of video are watched, with 72 hours of video uploaded every single minute.
I recently wrote about Twitter's super now app called Vine, which lets people create 6 second video clips that can be embedded in a tweet. Those videos have their own proprietary extension, but if you want to turn those 6 second videos into an animated GIF, you can now do so thanks to developer Esten Hurtle, who created VineGifR, a seamless way to transform your (or someone else's) Vine movies into GIFs.
Welcome back my fellow hackers! In my last few articles, I've concentrated on what is called a listener, which is basically the same thing as backdoor and rootkit, only "listener" sounds much less malevolent than the other two terms.
In my last hack blog on crashing your roommates Win7 system, we started looking at client- side attacks. As promised, we will be looking at some more client-side attacks.
There's really nothing safe about transmitting sensitive information electronically, but even if it gets there safely without being seen by prying eyes, there's no guarantee what happens to it once it reaches its destination. And let's face it, there are some things that you just don't want floating out there forever. So what can you do? Whether you want to send an email, a text, or a link, there are ways to send messages that self-destruct so that once they're read, they immediately vanish. ...
All of my hacks up to this point have been operating system hacks. In other words, we have exploited a vulnerability usually in an operating system service (SMB, RPC, etc.) that all allow us to install a command shell or other code in the target system.

The "Zoombombing" trend is still strong on the Zoom video meetings service, despite security measures Zoom put in place to stop it. That's why it's up to you, as either a host or co-host, to be proactive about preventing Zoombomber harassment, as well as stopping it whenever it slips through the cracks.
Ads aren't the only annoying part of navigating websites in Safari. Colorful banners, autoplaying videos, embedded objects, and other distracting elements can make it harder to read or watch what you want. Although ad blockers are one answer, they only get rid of advertisements, so you'll need something else to remove other irritating elements from your favorite websites.
What if, back in 2013, Google Glass had launched not as a Star Trek Borg-like eyepiece, but as a pair of seemingly normal shades, with the augmented reality lens and camera hidden within the frame?
Curve stitching is a form of string art where smooth curves are created through the use of straight lines. It is taught in many Junior High and High School art classes. I discovered it when my math students started showing me the geometric art they had created.
Bud Light being the official beer sponsor of the NFL just makes sense for American football. But what about the NHL, with hockey being the official winter sport of Canada by decree?
At Next Reality we mostly focus on augmented reality, but that doesn't mean we're not also absolutely obsessed with virtual reality, too. If the thing that's been keeping you from diving into the deep end of VR has been clunky tethered headsets or the expensive but necessary gaming PCs, then it's time for you to try the Oculus Quest, which is currently available to buy here for less than most gaming systems on the market.
With its 3D engine being responsible for approximately 60% of augmented and virtual reality experiences, Unity is continuing to place a premium on tools that not only keep developers working in its development environment but also make their workflows easier.
With iOS 13, Apple included some major updates to the Reminders app for iPhone. Among them is the ability to add web links to individual reminders, including a rich preview of the link that can be minimized if necessary. So now you can add an Amazon link in a reminder to buy a present or a webpage for a recipe in your grocery list, to name just a few examples.
Apple's Gatekeeper security software for macOS (Mac OS X) is vulnerable to remote attacks up to version 10.14.5. An attacker that's anywhere in the world can exploit MacBooks and other Mac computers by sharing a single ZIP file.
Now that Microsoft has squarely focused on the enterprise market with the HoloLens 2, it appears Lenovo is content to play follow-the-leader with its new augmented reality headset.
It's confession time. Through a couple of sources, I managed to get an early look at the HoloLens 2. But I was sworn to secrecy, and I take my tech oaths seriously (shame on you, leakers).
