Hi everyone! In the previous part of this series, I introduced one way to hijack a program's execution flaw, though I only showed you how to crash the program and left you with a little mystery to solve. Today we are giving the solution of that and then introducing shellcode usage and remote command execution.
Hi everyone! Last time we finished analyzing the assembly representation of our vulnerable piece of code (have I ever told you it is vulnerable?). This time we are going to introduce some fundaments about exploitation by demonstrating how to crash a program's execution. If that sounds lame, next time we will see how this crash can in fact be useful to control the program's execution, achieving remote code execution!
"Cheating is for losers" is only something that losers like to say. If you want to smash your friends and fly up the leaderboards, though, sometimes you have to go that extra mile.
There is something special about a secret knock. It gets you into secret super villain meetings and is a surefire way to test for rotating bookcase passages. Secret knocks usually work with an intimidating drug lord and for policeman listening at the door for the correct pattern of raps.
Amazon Prime Day is nearly here, but that doesn't mean the deals are a mystery. Sure, most of Amazon's best sales and discounts won't be announced until Prime Day itself, but we already know some awesome smartphone deals thanks to a handful of early sneak-peeks.
Publicly, things have been pretty quiet over at Meta, the augmented reality headset and software startup based in Silicon Valley. But that doesn't mean that the company doesn't have a few strong opinions about the state of AR in 2018.
A week after the L.E.A.P. Conference, our cup of Magic Leap news continues to floweth over, with the company's content chief giving us some insight into the company's strategy, and Twilio sharing what its virtual chat app looks like.
In the lead up to the Magic Leap One launch, Magic Leap has been coy about what the actual field of view (FoV) is for its first commercial product.
With the reveal of Magic Leap's developer documentation last week, many questions have been answered—and several new ones have been raised as well. But since the Magic Leap One (ML1) isn't simply called the "Leap One," these are questions that the company probably has no interest (at least for now) in answering. Understandably, Magic Leap wants to keep some of the "magic" under wraps.
Now that we've had a chance to jump into the Lumin SDK documentation at Magic Leap's Creator Portal, we now have much more detail about how the device will function and utilize software than any single piece of content released by Magic Leap to date.
As the level of data being generated grows exponentially, past the Information Age and into the coming Hyper-Information Age of immersive computing — as resistant as many of us are to the idea — personal data security is becoming a necessary consideration in our everyday lives. Recognizing this, Mastercard, Qualcomm, and Osterhout Design Group have teamed up to show what secure shopping could look like in the very near future with iris authentication.
People who have heart disease get shingles more often than others, and the reason has eluded scientists since they first discovered the link. A new study has found a connection, and it lies in a defective white cell with a sweet tooth.
As summer mosquito season approaches, researchers are warning people with previous exposure to West Nile virus to take extra precautions against Zika. A new study found that animals with antibodies to West Nile in their blood have more dangerous infections with Zika than they would normally.
Call them what you will—moss piglets, water bears, or by their real name, tardigrade—but these intriguing tiny creatures can come back from the brink of death. They can survive boiling, deep freezing, UV radiation, completely drying out, and even a trip to space—without the benefit of being in a spacecraft.
Maternal infection with genital herpes, or other pathogens, during early pregnancy could increase risk of autism, or other neurodevelopmental disorders, says a new study.
Using mathematical modeling, researchers suggest weather and warming created the "perfect storm" that drove the Zika outbreak in 2016.
Pie crusts are pretty intimidating if you're an at-home baker with little experience, since there's a lot of science behind making them. A perfectly flaky crust that's golden brown—not charred and black along the edges—requires careful attention, a foolproof recipe, and some decent baking skills.
No summer season would be complete without potato salad, an essential side dish. The flavors and textures of a simple potato salad can be totally satisfying as is, but add in a few items and you can have a dish that is absolutely extraordinary.
There are tons of greasy drippings that can be used to flavor up any dish, but none will ever be more delicious than animal fat. The bigger and fatter the animal, the juicier and tastier their fat is. For those of you who have had your fill of bacon-anything, here's your next obsession. It's called caul and its very existence will divide those that are serious about their animal fat flavoring from the pretenders.
You've probably used Google to search for recipes, or to find out what the heck that mystery food on the ingredients list is. But with all its built-in features, there are plenty of other ways the search engine can help you out in the kitchen.
The creation of private browsing was brought upon by the backlash against ad tracking and other ways that sites and agencies take away users' privacy online. People were tired of getting spammed with ads for Vitamin C pills simply because they visited WebMD. Private browsing is now built into all of the major browsers and is used frequently. While private browsing is more infamously known as the "Porn Portal," and does prove to be a great way of keeping racy content out of the sight of others...
HomePod and HomePod mini are excellent smart speakers if you're entrenched in the Apple ecosystem. They even offer ways to protect your sensitive information from friends and visitors who try to ask Siri to spill your secrets. But there's an extra layer of privacy you can put in place to make sure nobody gains access to any important notes, reminders, and calendar events.
If you keep your iPhone's home screen obsessively tidy, new apps are the bane of your existence. Hyperbole aside, they automatically fill the first available space on your home screen, starting on the second page, which can wreak havoc on your carefully planned layouts. With iOS 14, however, you can auto-hide new apps so that you never see them until you want to.
Staying inside during the coronavirus pandemic isn't easy for most of us. As important as it is to keep away from others, it can be challenging to keep to ourselves day after day. That's why mobile game developers are stepping in to help; many are making their games free for a limited time, to provide some much-needed fun during scary times.
What does mainstream augmented reality look like? I'm not talking about the stuff you see in concept videos and science fiction films. No. What does it really look like?
While everyone was marveling at the latest drama over at Magic Leap involving employees last week, a major rumor listed in one of the reports, related to the company's flagship device, was mostly overlooked.
The reveal of Magic Leap One: Creator Edition brought with it some insight into the path the device took from prototype to "final" design.
Just in time for the holiday season, Lenovo has released its Mirage AR head-mounted display with the Star Wars: Jedi Challenges game and accessories. Unfortunately, while its price point is a fraction of most other AR headsets, at the moment, it does have a few issues with the setup process.
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...
Now that Fyre Festival co-founder Billy McFarland is charged with fraud, this is the perfect time to list off those top 15 influencers who promoted tickets to the disastrous event to their loyal followers, right?
HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.
Six people have died from fungal infections in Pittsburgh hospitals since 2014—that fact is indisputable. The rest of the situation is much vaguer. A lawsuit has been filed against the hospitals on behalf of some of the deceased patients, alleging that moldy hospital linens are to blame. While the lawyers argue over who's at fault, let's look at how this could have happened.
A recent study underscores a connection between climate change and infectious disease, raising concerns about our quickly warming planet.
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.
The sweet aroma of cooked fruit filling your kitchen is one of the trademark scents of summer. Yet attaining the perfect consistency for homemade jam can be difficult to master. Often it ends up a watery mess or over-solidifies into thick mystery goo that is destined for the trash, not topping your toast.
One of the common complaints about dry pasta is that it lacks depth of flavor. This is why, once cooked, it often pairs best with bold and complexly flavored sauces.
I've been a diehard Chrome user since its inception, and even more so since Android was released. The ability to sync bookmarks, passwords, and web history across all of my devices made the switch a no-brainer, but what really made me fall in love was the amount of extensions available for it.
Deep in the crevasses of the Songshan mountain range, an Indian dhyana master established the first Shaolin Monastery in 477 AD, seeking to spread the relatively new teachings of Buddha at the time. This monastery then bred the Shaolin monks, who are now popular for their incredible feats with Chinese martial arts, particularly with Shaolin Kung Fu.
The director of 100 Musicians and Nurse/Fighter/Boy talked with us about old school filmmaking Charles Officer has directed shorts, music videos for K’naan, and the features Nurse/Fighter/Boy and Mighty Jerome, a documentary about Canadian track star Harry Jerome. His new short 100 Musicians, which screens Monday as part of Short Cuts Canada, is a small ode to civic optimism, concerning itself with a lovers’ argument over who exactly misheard a radio DJ reporting the plans of Toronto’s much m...
The company augmented reality that Rony Abovitz was trying to build at Magic Leap apparently wasn't working out the way he hoped it would. That company, built on dreams, music, and future-looking entertainment, rather than truly new technology, came with a $2,300 price tag for a device using dynamics most mainstream consumers have never even tried.
