Welcome back, my amateur hackers! Over the course of the next year, we will be developing our own zero-day exploits. In my first article in this series, I introduced you to buffer overflows, which are the source of some of the most lethal exploits, particularly the "remote code execution," so we are focusing our exploit development here on a buffer overflow.
While most people build collections of things with intrinsic value such as coins, stamps, or rare post cards, I collect wine corks—the natural ones, not the plastic kind. Corks are a natural product harvested from the cork oak tree. It takes the better part of 10 to 12 years before a tree can have its bark manually removed for the production of cork. Thankfully, no tree is harmed in the process and in 12 years, the tree bark can be harvested yet again.
Fall is my favorite time of year, yet I cringe every time it begins. Why? Because it seems like every business is in a frenzy to start the Christmas shopping season the day after Halloween ends. For those of us who are fans of pumpkins, that's a buzzkill.
Humans in general are great at keeping things about themselves private, from feelings to personality traits. While smartphones and social networks are making these secrets more open, narcissists have and always will love being out in the open with everyone's attention on them.
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.
Welcome back, my budding hackers! In previous tutorials, we've looked at some of the basic commands and concepts for using Linux. Along the way, I realized that I've failed to provide you with some basic background material on the stdin, stdout, and stderror.
Welcome back, my budding hackers! As you know, I firmly believe that to be a true professional hacker, you need to be proficient in Linux. This is for a number of good reasons.
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.
Welcome back, my fledgling hackers! Awhile back, I demonstrated one of my favorite little tools, netcat, which enables us to create a connection between any two machines and transfer files or spawn a command shell for "owning" the system. Despite the beauty and elegance of this little tool, it has one major drawback—the transfers between the computers can be detected by security devices such as firewalls and an intrusion detection system (IDS).
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...
If you want to make clothes for your cat, you're on your own. As I recently said in this article, cats will just totally flip out if you make them wear things. Your dog may also flip out, but I've found them to be more tolerant, personally.
n this pet care series, you will learn everything you need to know to be the perfect parakeet owner. As pets, they are easy to care for, especially when compared to the food demands of larger pets such as cats and dogs. All you need is a cage and birdseed, right? While this is true to a certain extent, there are specific requirements for a parakeet cage.
In this series of video art lessons you’ll learn basic tips and techniques for drawing cartoon animals. Artist, illustrator and expert cartoonist Paul Louis guides you step-by-step, teaching you how to create lines, add shading and use proportion to draw some of the most popular cartoon animals, including a cartoon dog, cat, duck and mouse.
There's not much you can customize on your iPhone's status bar beyond showing or hiding the battery percentage icon. You can't choose different icons or pick a vibrant color, but there's a secret trick that lets you bold all the text.
If you've ever used your iPhone's hidden Field Test mode to view your signal strength in decibel-milliwatts, locate the tower you're connected to, or find out the radio frequency in use, you no longer have to dig through all of the confusing-looking data every time you need to check. Apple updated Field Test's interface in iOS 15, and one improvement gives you more control of the Dashboard.
Brands are increasingly adopting augmented reality to promote their products and services, and they have multiple paths for bringing AR experience to their audiences.
Ah, the dreaded "green bubble" group chat. All it takes is one non-iPhone contact to turn an entire thread from iMessage paradise to SMS slog. Normally, it isn't that bad since the group chat still functions. However, sometimes, you end up getting messages individually instead of in a single group thread. Before you go blaming your Android friends, know that the issue is probably on your end.
The Chicago Bulls may not be very relevant in the current NBA standings, but they do lead the league in one other area.
If you buy an Android phone from any of the big US carriers, it will come with several extra apps in addition to any apps the manufacturer preinstalled. It's all in the name of profit, of course. Some of these apps are from companies that paid the carriers to distribute their software, and some are from the carriers themselves, usually aimed at upselling you or perhaps collecting a little data.
During this week's unveiling of the new Samsung A Series of smartphones, much of the focus was on the high-end features at a more affordable price as the South Korean tech giant looks to regain its status as the world's top smartphone maker versus Apple's iPhone.
When an app needs to be absolutely sure it won't be cleared from RAM by Android's memory management system, it posts a persistent, ongoing notification. Another time you'll encounter non-removable alerts is when your phone or carrier really wants you to do something, like apply an update.
Android Messages, formally named simply "Messages" now, has built-in spam protection. This doesn't get every spam SMS message, however — in fact, you can still get unwanted texts multiple times daily even with the feature enabled. Thankfully, you can manually block numbers, too.
Amber, emergency, and public safety alerts on an iPhone are loud — startle-you-to-death loud even. They can happen at any time, day or night, and sometimes back to back when you're in a big city. Those blaring sirens can wake you from sleep, interrupt an important meeting, or disrupt an entire movie theater mid-movie, but you can turn most of them off if you're tired of hearing them.
If you upgrade to an iPhone 12, 12 mini, 12 Pro, or 12 Pro Max, you can take advantage of super-fast 5G speeds, but which 5G network are you actually getting and is it better than the others? Depending on your carrier, you may see 5G, 5G+, 5G UW, or 5G E in the status bar next to the signal strength, and there's a pretty big difference between them.
Let's say that the screen on your iPhone is showing signs of discoloration, which makes the display annoying to use. You'll need a replacement display or a new iPhone as soon as possible. If you have one of the newer iPhone models, the cost to fix it might be more than your wallet can handle, but a warranty may still cover it, and there are ways to check quickly.
Most streaming platforms have seen a huge viewership increase in the past few months. As a result, wireless carriers and ISPs are struggling to provide the necessary bandwidth for everyone, resulting in some customers being limited to DVD quality. The same applies to YouTube, YouTube Music, and YouTube TV, but you can see the resolution being used and change it to something better.
Previously limited to apps like Facebook and YouTube as an in-app feature only, picture-in-picture mode is now an OS-level feature in iOS 14. That means any app can quickly flip the switch to let you watch videos in an overlay window while you multitask in other apps. However, sometimes you only need to hear the audio and not see the video, and that's totally possible too.
Samsung decided to jump into the foldable category early, announcing the Galaxy Fold in February 2019. After a major hiccup, Samsung released the phone four months later to praise. But Samsung's not finished with foldables, as the new Galaxy Z Flip is just on the horizon.
Sorry, Galaxys S11–19, Samsung's jumping straight to Galaxy S20 this year. They're also going with essentially three base models before accounting for niche variants. Of these three models, it's clear which one's the best: the Galaxy S20 Ultra.
After months of back and forth, ZTE is finally making their return to the United States. The last phone the Chinese company released here was the Axon 7 Pro, a low priced flagship phone that competed well against the OnePlus 3 and 3T at the time. Its successor is the Axon 10 Pro, which adopts the same strategy.
It's easier than you might think to hack into Wi-Fi routers using just one unrooted Android phone. This method doesn't require brute-forcing the password, a Windows OS for converting PowerShell scripts into EXE format, a reliable VPS for intercepting hacked Wi-Fi passwords, or Metasploit for post-exploitation tricks.
In 2019, Sony is mixing up its design, attempting to stand out among the sea of familiarity. Instead of emulating Samsung with punch hole cameras, they decided to target a rare section of the market, content consumers. There's the Xperia 1 for those who want the best, and the Xperia 10 and 10 Plus for the budget crowd.
After months of waiting, it looks like HMD has finally answered the call. Nokia's parent company is finally releasing a true flagship phone — one that isn't just an enhanced version of a previous phone and actually brings something new to the table. That phone is the Nokia 9 PureView.
For 2019, Sony is trying to shake its failures of the past and start fresh. Following the unsuccessful Xperia XZ series, Sony is changing the name of their flagship to a single number: Xperia 1. With the name change comes a few upgrades, one of which is its new look. Secondly, its new display is unmatched in the mobile space.
Once again, LG is mixing up its launch. Instead of the announcing the latest entry in G series later in the year, the LG G8 ThinQ was announced at Mobile World Congress 2019, shortly after Samsung's Galaxy S10 event. And instead of trying to match what other OEMs are doing, LG is once again trying to be different.
On the surface, Instagram is pretty intuitive, so you might think that you already know everything there is to know about using it on your iPhone or Android phone. But this photo and video-sharing app is constantly adding new features, some of which don't make the press releases. Even if you're an Instagram guru, chances are you've missed one of these hidden goodies.
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.
Apple officially released iOS 12 to everyone on Sept. 17, and while the new iPhone XR, XS, and XS Max will come with the software by default, you have a choice on whether or not to update your current iPhone model from iOS 11. There are a lot of tempting features to want to update right away, but there are also some compelling reasons to wait it out and install at a later time.
After getting confirmation from Tim Sweeney, CEO of Epic Games, we now know Fortnite Battle Royale will not be available on the Play Store when it's finally released for Android. Instead, users will have to download the APK directly from Epic Games' website — and quite frankly, this is a bad idea.
| Updated February 11, 2019 with new phones. When will my phone get Android Oreo? That's a question still being asked by many, even this late in 2018. Most OEMs have answered this question in one way or another, either releasing a stable OTA or confirming their device won't be receiving the update. We consolidated all these responses, and here's where we stand.
