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.
Thanks to Apple's ARKit 2.0 augmented reality framework in iOS 12, we now have a "Measure" app built right into our iPhones that can measure real-world objects. No more physical tape measure or ruler. No more guessing. Just whip out your iPhone, open the app, put your camera, and get measurements. Before you do, however, there are a few things you'll want to know.
Samsung hopes to make a splash with the new Galaxy Note 9 to make up for the underwhelming sales of its signature Galaxy S9 series. This flagship is a radical departure from its predecessors — it's now optimized for gaming and paired with the most advanced S Pen stylus to date. Here's everything you need to know.
Get Out absolutely tore up the record books this year. And the wildest thing about it? It did so with the most ordinary looking characters and props ever (hence the shoestring $4.5 million budget). Which makes it a godsend for the time- and cash-strapped come Halloween. With Get Out, Jordan Peele is the first (and only) African-American writer-director with a $100-million film debut under his belt. The film is also the _all-time highest domestic grossing debut based on an original screenplay ...
If you have a taste for sweets, you have at least one thing in common with mosquitoes. While too much sugar is unhealthy for humans, a new product makes sweets deadly to mosquitoes.
Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...
OpenVAS is a powerful vulnerability assessment tool. Forked from Nessus after Nessus became a proprietary product, OpenVAS stepped in to fill the niche. OpenVAS really shines for information gathering in large networks where manual scanning to establish a foothold can be time-consuming. OpenVAS is also helpful for administrators who need to identify potential security issues on a network.
While some researchers look for drugs to treat HIV, other scientists delve deep into the virus itself for answers on how it causes infections.
A recent study underscores a connection between climate change and infectious disease, raising concerns about our quickly warming planet.
What's in a sneeze? Quite a lot—dirt, mucus, and infectious germs—it seems. And sneezing the right way can reduce the germs you share with neighbors.
To much of the United States, Zika seems like a tropical disease that causes horrible problems in other countries but is nothing to be worried about stateside. It may make you rethink your beach vacation abroad, but not much more than that. However, if you live in Florida or Texas, the possibility of getting a Zika infection where you live is real — and local outbreaks are more and more a possibility.
How do I get rid of these zits?! Whether its pimples, blackheads, or whiteheads, the name is the same, and the name is acne.
The big night is less than a week away, so how do you not have a costume yet?! In my world, Halloween is the night of all nights. It's the only day of the year when it's socially acceptable to dress and walk around like an insane person, eat too much sugar, and scare the hell out of total strangers. What's not to love?
Gaining access to a system is always exciting, but where do you go from there? Root or bust. Sure, a compromised host is a great way to run a botnet, or do some other boring, nefarious thing—but as hackers, we want root. We also want to take the easiest path possible, search out low-hanging fruit, and exploit them. SUID programs are the lowest of the low-hanging fruit.
The yogis of the internet have started a wonderful food trend that has everyone wanting to eat healthy—gorgeous buddha bowls. Okay, so maybe not everyone, but a lot of people are definitely entranced by these beautiful, multicolored meals.
If your iPhone has a Home button, such as either iPhone SE model, old or new, then it has a secret triple-click gesture to activate a suite of shortcuts. These options, dubbed accessibility shortcuts, can work wonders for folks that are hearing impaired, have limited use of their hands, or have vision problems. Still, the shortcuts have plenty of everyday applications that everyone should know.
Most of you lot would be aware what WPA/WPA2 is so I won't bang on about the encryption or protocols a great deal. In short WPA and WPA2 both have a maximum of 256bit encrypted with a maximum of 64 characters in the password. The encryption is really only 64bit but x 4 because of the way the authentication functions as a 4 way handshake.
What's up readers? Today I'll be introducing to you a new vulnerability called the Format String vulnerability (in case you missed the title). It won't be much, just a little motivation to keep you guys going. A little teaser, if you may.
So this is my methodology for this project of writing a rootkit. Please leave feedback on what is right/wrong. I tried to simplify concepts the best I could however...
Welcome, in this tutorial we shall we looking at creating a safe(r) way to back up your important files. The contents we will be covering are as follows;
Taste is certainly relative. When you look at Central American architecture and notice all of the bright pastel colors, then move just a thousand or so miles to the north and see that buildings in the United States are mostly painted in earth tones, this becomes abundantly clear. Imagine if you were to switch hemispheres altogether—what would you see in East Asia?
As someone with a pretty nice TV, I've never found the allure in purchasing a projector. While they're certainly smaller and sleeker than a television, and more portable, they can be pricey and produce a less than stellar image. And who really buys a projector anyways? They're for school, they're for work, they're for theaters, but they're not really for my apartment, right?
Welcome back, my hacker novitiates! Every so often, a MAJOR vulnerability appears that makes millions of systems vulnerable to attack. The most recent, named Shellshock, basically leaves every Mac OS X, Linux, and UNIX system on the planet vulnerable. As nearly two-thirds of all web servers on planet Earth run one of these operating systems (primarily Linux), that's a whole lot of systems out there waiting to be harvested.
Welcome back, my budding hackers. So many of you are interested in hacking Wi-Fi that I have decided to revisit my Wi-Fi Hacking series with some updated and more in-depth material. I strongly suggest that you look at some of my earlier posts, such as "Getting Started with Terms and Technologies" and "Getting Started with the Aircrack-ng Suite of Wi-Fi Hacking Tools," before continuing here. If you're ready, you can also check out our updated 2017 buying guide here.
Biting into a perfectly ripened piece of fruit is enough to convince you to give up baked goods and plant your own garden. The combination of flavor, juice, and sweetness in a ripe mango, apple, plum, or berry is the stuff of life itself.
I love me some salad, but I'm also kind of a big baby when it comes to eating them. The greens have to be perfectly crisp and fresh, which is why I'm such a nut about storing them properly, including rethinking how I use my refrigerator, using a paper towel or dry cloth to wrap them, or even puffing a little CO2 into the plastic bag to keep them fresh. I've even developed an arsenal of tricks to restore life to soggy greens.
If you've already read the first part exploring what geniuses actually eat as opposed to what the rest of us are told to eat for brain health, you've noticed that there are some big discrepancies. Instead of favoring healthy, wholesome foods high in antioxidants, lots of high-achieving types tend to go for caffeine, sugar, and processed foods. One notable health habit practiced by many: eating breakfast.
We all know that it's important to drink water regularly throughout the day. After all, it has so many benefits, including flushing toxins out of the body and maintaining kidney health and good bowel movements. Turns out that's only part of the story. While being properly hydrated is key to maintaining overall health, it's also a big component of maintaining and even increasing cognitive ability. Plus, drinking enough water regularly can help you lose weight, if you know when to drink it and ...
Welcome back, my fledgling hackers! As nearly everyone has heard, Target Corporation, one of the largest retailers in the U.S. and Canada, was hacked late last year and potentially 100 million credit cards have been compromised. Happening just before Christmas, it severely dampened Target's Christmas sales, reputation, and stock price (the company's value has fallen by $5B).
Every home cook has their most-hated kitchen task. For me, peeling hard-boiled eggs and garlic are pretty high up there. Actually, peeling just about anything is, but for every annoying job, there's a shortcut to make it easier.
At one point in the '90s, about fifty percent of the CDs produced worldwide had an AOL logo. About fifty percent of the CDs in my home still have that AOL promise of 500 free hours on them. Though they never got me to join their internet service, I did get a lifetime supply of coasters. Thanks to the rise of high-speed internet access and bigger and better hard drives, there's no reason for companies to snail mail any more of those obnoxious plastic discs.
As we all use our smartphones for more and more things, we constantly want to share and view those items on a larger screen, especially when it comes to media. While phones like the Samsung Galaxy Note 2 and tablets like the iPad do make watching Netflix on a portable device pretty legit, bigger is always better. Newer iPhones may have Retina displays, but watching Avatar on your phone is like being forced to drink a delicious mango tango smoothie with a coffee straw. Plus, if you want to sho...
Sherlock Holmes is one of the most famous characters in modern history, and has appeared in film more often than any other character. No less than 78 different actors have taken their turn at portraying the enigmatic deduction machine in various mediums, and each has brought their own foibles to the role. Some of the names may even surprise you: Tom Baker, John Cleese, Peter Cushing, Charlton Heston, Christopher Lee, Roger Moore, and even Leonard Nimoy.
Back in 2007, YouTube user HouseholdHacker posted a parody video on how to make a high-def speaker for under a buck. MythBusters took on the challenge and busted it.
In the first part of this series, we took a factual and technical look at the history of the Internet. I explained how all of these wires and servers got here in the first place. Obviously, a firm did not just create and build the Internet around 1995! Now that we know how the Internet came to be, we can get into the really fun stuff—what the Internet looks like now! Well, that's not quite the network design I was talking about, but it does show what the Internet looked like back in 2007 befo...
In this video series, landscaping expert Fernando Chavez teaches how to install a sprinkler system. He teaches what tools and materials are needed, how to design a sprinkler system, how to maneuver around cement, corners, and curves, how to lay sod, how to install sprinkler heads, how to cut and connect PVC pipe, how to dig trenches, how to install the valve, and how to set the time for an irrigation system. Let Expert Village help you start your next landscaping project with this helpful new...
Whenever you need to digitally share large bodies of real-world text, you'd likely show a photo of it or manually type everything into the document or chat. But iOS 15 has a much better way for your iPhone.
Identifying security software installed on a MacBook or other Apple computer is important to hackers and penetration testers needing to compromise a device on the network. With man-in-the-middle attacks, packets leaving the Mac will tell us a lot about what kind of antivirus and firewall software is installed.
PowerShell is an essential component of any Windows environment and can be a powerful tool in the hands of a hacker. During post-exploitation, PowerShell scripts can make privilege escalation and pivoting a breeze, but its execution policy can put a damper on even the best-laid plans. There are a variety of methods, however, that can be used to bypass PowerShell execution policy.
The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.
