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.
It is often said that the best hackers remain unknown, and the greatest attacks are left undiscovered, but it's hard for an up-and-coming penetration tester or white hat to learn anything unless one of those factors is actually known or discovered. But the end goal here in our SQL injection lessons is to make that statement as true as possible for us when performing our hacks.
This is a tale about microbes, a man who became a hermit, and the parchment that carries both of their stories.
When the climate changes, so do all the things that rely on the climate, including people, plants, and pathogens. A European study recently took a broad look at what kind of microorganisms are most likely to be affected as climate change heats, cools, dries, and wets the world around us.
Forget the rise of the machines. Tardigrades are set to outlive everything — even the bots. When the last echo of a whisper in a cell phone has long dissipated into space, the water bears will still be hanging out.
For a company more associated with debugging computer programs, Google's parent company, Alphabet, is making a name for itself by taking on the real thing — mosquitoes.
Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it.
Dengue fever is a danger to anyone living or visiting tropical or subtropical regions. It can be hard to detect the infection in its earliest and most treatable phase, especially in children. Luckily, new research highlights better techniques for triaging the disease in infected children with more severe symptoms, potentially saving lives.
Fighting fire with fire, scientists are harnessing the adaptability of helpful microbes to challenge the adaptability of deadly microbes. What are we talking about? Hunting with phages — viruses that attack and kill bacteria.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
On October 17, 1943, a story in the New York Herald Tribune read "Many laymen — husbands, wives, parents, brothers, sisters, friends — beg Dr. Keefer for penicillin," according to the American Chemical Society. Dr. Chester Keefer of Boston was responsible for rationing the new miracle drug, penicillin.
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
An outbreak of anthrax from contaminated meat in Tanzania sickened dozens of people and moves the danger of this deadly bacteria back into focus.
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.
A gold-medal winning entry into the iGEM synthetic biology competition could change the way we look at Esherichia coli, the bacteria better known as E. coli.
I'm sure I'm not the only one on here that has googled "Why am I always tired?"... and I'm definitely not alone when I say that all of the advice I've found so far is useless:
The sprouts, they're alive! Alive, I tell you—aaaaaaliiiiiive! (Cue dramatic music.) It's true: sprouts are a living food, and they're packed with more nutritional benefits than some raw vegetables. It's easy and fun to grow your own sprouts from seeds, legumes, and grains. Plus, watching them grow is incredibly satisfying—you're bringing new life into the world (and onto your plate)!
Caramel is delicious, but it can be a tricky flavor to incorporate into baking. Traditionally, caramel is a liquid, and that doesn't always suit dessert preparation since adding extra liquid to baked goods can ruin them. So how do you get that buttery, toffee-like flavor?
Hanukkah, also known as The Festival of Lights, commemorates the rededication of the temple in Jerusalem in 168 BCE. (Jews and secular publications, such as academic or scientific papers, use BCE—"before common era"—rather than the Jesus-centric BC, or "before Christ.")
3D Touch is a new feature on the iPhone 6S and 6S Plus that's reinventing the way we interact with our smartphones. With just a little bit of added pressure when tapping on the display, you can perform Quick Actions from an app's home screen icon, "Peek" at emails, stories, and photos in-app, as well as perform other app-specific gestures. Since 3D Touch is such a new concept, here are some of the apps that currently support it, along with the shortcuts you can use.
Preparing and serving seafood can be a daunting task. Fish is so delicate that one extra minute of heat can turn a juicy, flaky filet into a dried-out disaster. But that same fragility also allows us to use unconventional methods to chemically transform the fish into its cooked consistency.
Welcome back, my novice hackers! In this third installment of my Hacking Web Apps series, we will look at the authentication of web applications. Remember, there are many ways to hack web applications (as I pointed out in my first article), and cracking authentication is just one method.
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.
Cheese might be one of the most satisfying snacks around, whether you prefer a slice of snappy Irish cheddar or a creamy, rich portion of Brie. It's been called "dairy crack" by a respected physician and for good reason: eating cheese produces casomorphins, which effect the human body like opiates. It also contains trace amounts of actual morphine.
Willpower is a pretty significant word. It's the difference between sticking with a clean eating diet and diving face-first into a plate of brownies. It's what drags you out of bed on Monday mornings and into work rather than letting you stay snuggled under the covers asleep. And, most importantly, it's the kick in the butt we all require to both accomplish goals and make changes.
There are so many cutesy pink, red, and heart-shaped desserts and drinks put out on Valentine's Day, but none of those really get you into a low-light mood. Instead, turn up the heat with one of these aphrodisiac cocktails for grown-ups.
Certain ingredients that a professional chef might work with in a restaurant-style setting may seem bizarre, dangerous, and even downright scary to a home cook, and for good reason.
Bottled water is a rip-off. Not only is it pretty much the same stuff that comes out of your tap for free, but plastic bottles are rarely recycled and thus account for a huge amount of the waste that's overflowing our landfills. Next Up: Water Bottles You Can Eat
You've been there. Those precarious few seconds between dropping your expensive smartphone right on its face and reaching down to survey the damage. Or maybe you got thrown in a pool while your device was in your pocket, or you dropped that sucker right into the toilet bowl. Heck, I've managed to accidentally wash two devices by leaving them in my pants pocket when throwing in a load of laundry.
Apple is widely known for keeping a tight grip on iOS, disallowing open-source and third-party downloads. While there are many reasons for this, the three most frequently referenced are quality control, malware prevention, and of course—money.
Living in Los Angeles has taught me one thing—parking is a luxury. If you are lucky enough to find street parking anywhere near your desired location, do not pass it up thinking you will get an even closer one. It does not exist. Looking for free parking? Get real. You can't even park at a busted meter in Los Angeles, despite state law saying otherwise. Now, finding a good parking spot is not just relevant for Los Angeles, but for other large cities and any other crowded areas, be it a shoppi...
Religion is one of the most-ignored topics when it comes to Steampunk, which is surprising given how important religion was in Victorian England. Even the hot-button issues of race and gender are confronted with a greater awareness than religion.
Will the predicted apocalyptic date—December 21st, 2012—really be the end of the world? In this ongoing five-part series, we examine what would happen if zombies, nuclear weapons, cyber wars, earthquakes, or aliens actually destroyed our planet—and how you might survive.
There's only three weeks left until the spookiest holiday of the year, which means stores and costume shops everywhere are bringing out their Halloween inventory full force. So now's a good time to start prepping your Halloween costume—because you really don't want to do it last-minute again, do you?
