During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value. While that's all well and good, arbitrary values are boring. We want to gain full control over the values we write, and today we are going to learn how to do just that.
Welcome back, my budding hackers! One of the most basic skills the forensic investigator must master is the acquisition of data in a forensically sound manner. If data is not captured in a forensically sound manner, it may not be admissible in court. In my Kali Forensics series, I showed you how to acquire a forensically sound, bit-by-bit image of a storage device such as a hard drive or flash drive, but now let's dive into live memory.
It's no secret that exercise is good for you, but you may be surprised to know that a good workout can actually boost your memory, too. They key to giving your body and your brain muscles a good workout is by adding more weight and pushing hard for an extra 20 minutes.
Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
Android version 5.0 Lollipop introduced a ton of changes to the OS—and of course with new features, there's always a new set of bugs. One of the biggest bugs of all was a massive memory leak caused by the new screen-off animation, which loaded its assets into memory but never cleared them away.
Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...
The Memories feature in Photos is meant to help you rediscover old or forgotten experiences by creating a short slideshow of photos and videos based on locations, dates, and events. It's a fun feature to relive exciting times, but it isn't always perfect because it's generated automatically. It might include incorrect content, but in iOS 14, you can now create your own Memory Movies.
When you're trapped at your desk before a jumble of data just waiting to be categorized, or zoning out during an important meeting, your mind wanders and, chances are, you feel a little guilty because of it. Yet you shouldn't try to reign in that distracted thinking. Instead, let your brain get distracted, and you'll unconsciously strengthen your memory.
Having thousands of photos and videos in your Photos gallery can make it difficult to find the best ones, but your iPhone does make it a bit easier. Memories, which have been around since iOS 10, automatically group your photos and videos into mini-movies by location, date, or person. It's a fun feature that does the work for you, and it's getting better with the release of iOS 15.
Welcome back, my budding hackers! Digital forensics is one of IT's most rapid-growing disciplines. All hackers should be familiar with digital forensics if for no other reason than to protect themselves. More than one hacker has been apprehended because they were unaware of the evidence trail they left behind.
Every 5G model of the Galaxy S20 comes with 12 GB of memory. This amount of RAM is overkill, but Samsung's been putting similar amounts in its flagships for years. Since you have it, why not put it to use? With One UI 2, you can.
In the last tutorial, we learned how to make functions and how they work on the high level. This time, we will take a peek under the hood again, stare deep into its soul and see its ugliness face to face to see how it works in the lower level.
From day to day, it can be difficult to remember everything that's required of you. I tend to forget exactly where it is I'm supposed to be during my busiest moments, and it's even easier to delete each day's events out of your brain when there's so much else that dominates your mind. Yet taking the time to remember exactly what it is that happens during each of our days can be a vital part of our memory—and with nothing more than 15 minutes, we can strengthen our brains and remember more tha...
There's a lot going for the Samsung Galaxy Note 2—smart screen rotation, huge HD display, great rear camera—which makes it an awesome device for reading, watching videos, and taking pics. But all of those luxuries will end up hogging up your internal memory, which is one of the few things the Note 2 could use some help in. The device comes with 16 to 64 GB of internal storage, depending on your model, with the option of adding a microSD card for more space. Only problem is, everything automat...
Modern smartphones can easily handle anything you throw at them, but it's always good to keep a tight grasp of what your phone is actually doing and how well it's doing it. System information can be viewed by looking through your Application Manager, but this process makes it difficult to keep an eye on usage in real time.
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.
Hey guys, so today I am sharing a very special video in the memory of Talia Joy, as a mint mani for Talia as suggested by nail polish wars. Hundreds have already participated, and here is my version:
On mobile devices, the Notification Center received a huge facelift when iOS 8 was released, but it wasn't until Yosemite that its Mac OS X counterpart received the same amount of love—especially the much needed ability to add custom widgets, like a FaceTime dialer.
There are phones nowadays with 12 gigs of RAM, but they'll cost you well over a grand. The majority of Android devices have much less memory — I'd wager most have less than 4 GB. And with the system taking up around 2 GB, that leaves user-installed apps little room to breathe.
Hello, this is my first post on Null-Byte. This is made for those who have an interest in writing into another processes memory. Why would you want to do this? Who knows, personally I just wanted to mess around with games on my computer(have unlimited health).
Last week, Magic Leap gave us an additional peek at its Lumin OS and more tutorials that show how its device works with virtual content. But details about the hardware wasn't included in the array of new information.
While the increasing superiority of smartphone cameras is great, they can be a double-edged sword. Sure, we get great images that are crystal clear, but at what price? Storage space on your devices ends up paying the price for this luxury, filling up quickly due to the high-quality images and their grotesquely large size. Not only that, but most photo editing applications only make it worse. Adding a few filters, changing the hue/saturation, or adding some text across the picture can all incr...
They say a picture is worth a thousand words, but augmented reality is giving the United States Holocaust Memorial Museum the ability to add a few more poignant real words to its exhibits.
Perhaps the biggest new feature within Apple's iOS 17.2 update for iPhone is Journal, a new journaling app designed to help you take a moment to reflect each day using reflection prompts, recommendations via on-device intelligence, and suggestions for recent activities and events.
