Hi everyone. Recently I've been studying some topics about Assembly, memory and exploitation, and thought I could write something nice, easy and fast about it, just because I like to share what I learn, and probably sharing what you learn and trying to explain it to a stranger is the best way to learn it better. It worked for me, and I hope it will be useful for you too.
Humans are able to produce a wide variety of sounds in part because they have descended voice boxes that makes room for longer vocal tracts.
Legal Services A group of lawyers refused to provide legal services to needy AARP members for $30 per hour, but when asked to do it for free, they readily agreed.
As you have no doubt observed, brothers and sisters do not mate. While they may find one another attractive, they find the notion of sex with one another repulsive. This is because a child produced by siblings has a high probability of sharing the same recessive genes, and recessive genes are often harmful unless coupled with dominant genes.
In yesterday's tidbit, we learned that across the planet women seek material wealth in their mates. This stems from our hunter-gather past in which females depended on male hunters to provide them and their children the meat necessary to support their large brains.
One of the roles our government has taken on is to provide us with information to be used in making decisions.
Economists have long since known that people want to be rewarded for taking on risk. Investments are thus judged by their risk-adjusted returns (Sharpe ratios). A typical hedge fund has a Sharpe ratio of around 0.5. This means that its excess annual return over the risk-free rate is about half its annual standard deviation.
Before lead was removed from gasoline, lead from car exhaust got into the air, was breathed in by kids, lowered their IQs, and increased crime rates (there is a very strong correlation between IQ and criminal behavior).
Roughly five million years ago, humans split off from chimpanzees, who had in turn split off from gorillas five million years earlier.
Nicole Mead and Vanessa Patrick had a bunch of dieters, one at a time, sit and watch a movie, each with a bowl of candy next to him. Some were told they shouldn't eat the candy, while others were told that they should hold off during the movie but could have the candy later.
As we approach the holiday (i.e. gift-giving) season, don't forget to make sure to include the usual notes in your gifts indicating that they can be returned. Otherwise, you'll just cause the recipients to save your gifts until they can be properly regifted onto some other ungrateful chump.
Sea otters are the largest members of the weasel family. When people started hunting sea otters for their fur, their population fell from roughly 225,000 to about 1,500, until the International Fur Seal Treaty took effect in 1911. Since the international ban on otter hunting, the population has rebounded back to roughly 107,000.
When subjects are asked to watch a movie and not display emotions (say, a comedy without laughing, or a tearjerker without crying), they evidently use up glucose in particular areas of their brain in a way that subjects who are free to react however they want do not.
If you've ever mistakenly moved your music files around without relinking them in iTunes, you might now be noticing that you have a long list of tracks asking you to relink them. You could go through them one by one, redirect them to the new file location, then delete any copies. Or you could try to track them all down and delete the old references. But come on, who wants to spend that much time when you can clean up your library using this clever method using only Notepad on your Windows com...
Musical theater enthusiasts are about to enter a whole new world of melodic storytelling via augmented reality.
Although styluses and smartphones have existed together for years, the iPhone has always ignored the pairing. After all, "Who wants a stylus?" But ever since the Apple Pencil made its debut on iPad, the rumor mill has churned out the idea that an iPhone could one day see stylus support. That day will probably come with the release of iPhone 11, and there's a good indicator to make its case.
Google loves to play games. That's just what they did when they went ahead and teased us with a few Android O hints after Reddit user Zitroney unlocked an Easter egg in a Google Creative Lab developer's app ShortStories.
In this article I will show you how to obtain victim's credentials without cracking any hashes. There are a couple of ways to perform this task (for example dumping the SAM file and cracking the NTLM hashes), but here I will explain how to do it using PowerShell and a bit of social engineering. We are going to create a fake login popup.
Step 1: What Exploit Development Is and Why Should I Be Interested on About This Topic
Recently I was trying to install Kali Live on a USB drive with persistence and struggled to find a tutorial online that was simple and actually worked. After some trial and error I figured out how to do it correctly and decided to make an article for anyone who is experiencing the same difficulty I did. You will need an USB with at least 8GB. Mine is 132GB, nice and large.
Earlier this month, John Oliver spent a segment on Last Week Tonight explaining native advertising, a practice followed by many online media outlets such as BuzzFeed, The New York Times, and VICE, which combines editorial content along with sponsored advertisements.
Veering from common practice, XDA commenter, "the_commenter", discovered a changelog for the upcoming version of Android 4.4.3 tucked away on Google's servers.
Life has many perils: parasites, predators, and pitfalls. Eventually, any organism will succumb, and if that organism has not first passed on its genes, those genes will face extinction.
Humans clearly demonstrate altruistic tendencies towards other members of groups with which they identify.
Males fight for dominance in order to gain access to the limited supply of female eggs. This is why male birds expend energy on brightly colored plumage, but female birds do not.
In evolutionary times, we were far more likely to die from starvation than from diseases related to obesity. In those times, when food was available, it was best to stuff oneself.
Dianne Tice and Roy Baumeister gave a bunch of college students a questionnaire in which the students answered questions about their work habits. In a class which she taught, Tice also assigned a paper with a deadline which she said could be extended and observed which students availed themselves of the option to extend.
The Asana mobile app lets you manage your projects with the same functionality as the website. Most features are pretty straightforward, thanks to Asana keeping the same design cues from the web app. However, one element is very easy to miss: adding subtasks.
Months after Next Reality broke the story surrounding the financial troubles at Meta Company, there's a new update in the company's ongoing patent lawsuit.
It's long past time to face the facts: farts are funny. The first fart joke dates back nearly 4,000 years to the ancient Sumerian people. References to flatulence were also found in ancient Greece within the works of Aristophanes. (More like Aristo-fannies, am I right?) A standard in practical jokes, the whoopie cushion debuted way back during the time of the Roman Empire.
All Galaxy S8 models apparently weren't created equal. According to numerous user reports, it appears that Snapdragon-powered Galaxy S8 variants are using an older flash storage standard than what Samsung was originally advertising.
The latest Google Photos update for Android has added a number of cool new features, like video stabilization and a rumored Google+ integration. The latest update started rolling out to devices on April 11, 2017, and includes the video stabilizing feature we've been waiting for.
A couple weeks ago, GM's Cruise Automation released a remarkable self-driving video from the streets of San Fransisco that Driverless analyzed in detail. And now they've just released a new one giving more insight into their growing mastery of the complex roads in San Francisco, specifically, the Potrero Hill and Mission Dolores neighborhoods.
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.
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!
Hi everyone! Last time we explained what roles Ebp and Esp registers have. We first introduced function's stack frame building, return address and calling conventions, but left some of the concepts floating without a full stop.
Hi everyone! After messing around a little bit with IDA and Hopper disassemblers and briefly introducing you to memory, registers and Assembly, we are going to understand what happens when a process is running, which variables join the play and especially what happens when a function is called and why is this procedure-logic so interesting and useful along with the concept of stack.
As excitement looms for Apple's annual parade of pomp and circumstance for its latest lineup of iPhones, some hidden hints in an internal build of iOS 13 has Apple enthusiasts salivating for what Cupertino is testing in the AR wearables realm.
Safari has a convenient "Find" feature to search for specific words and phrases in a webpage, and Apple Books has a similar feature for e-books and PDFs. But those do nothing for you when searching text in the real world. Hardcover and paperback books are still very much a thing, as well as paper-based documents, and finding what you need is as simple as pointing your iPhone's camera at the page.
Each year, Apple seems to design its devices to be more difficult for owners to repair themselves. So when an iPhone breaks, a trip to the Genius Bar or an Apple Authorized Service Provider is most likely necessary. But if you have an iPhone X that needs a new battery, a leaked video just spilled the beans on how to replace the battery precisely as Apple would.
