Steganography is the art of hiding information in plain sight, and in this tutorial, I'll show you how to use Steghide — a very simple command line tool to do just that. In addition, I'll go over a bit of conceptual background to help you understand what's going on behind the scenes. This is a tool that's simple, configurable, and only takes a few seconds to hide information in many file types.
The Pixel 2 debuted a really cool feature that identifies any songs playing nearby and automatically displays the track's name on your lock screen. It's honestly one of the most inventive smartphone features we've seen in a while, especially considering how Google did it — but strangely, it's not enabled by default.
Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
Apple's iPhone 8 and iPhone X announcement went about exactly as the rumors predicted. Really, there was only one surprise — the fact that all of the new models will support the Qi wireless charging standard.
In the case of rotting food, microbes are not our friends. Now, scientists have developed a new food wrap coated with tiny clay tubes packed with an antibacterial essential oil that can extend the shelf life of perishable food, so we can waste less and eat more.
People infected with HIV take many different types of pills every day to decrease the amount of virus in their body, live a longer and healthier life, and to help prevent them from infecting others. That could all be in the past as new clinical trials testing the safety and effectiveness of a new type of treatment — injections given every four or eight weeks — look to be equally effective at keeping the virus at bay.
Telegram routinely boasts about its secure messaging for truly private conversations between two parties. However, default cloud chats in Telegram are only encrypted between client and server, not client and client, which means you have to be a little proactive in making sure your private conversations on Telegram are really private.
Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.
Bed bugs are parasites not yet known to spread disease — but they cause plenty of irritation. As scientists and landlords search for new ways to deal with the pests, a new study examines how we can deter bed bugs without so many chemicals.
Most people are familiar with the decline of honeybee colonies around the world. Among other threats, Colony Collapse Disorder (CCD) is eroding the capability of honeybees to maintain their hives and provide their services to human farmers.
The only official way to record your iPhone's screen before iOS 11 was to hook it up to a Mac and use QuickTime Player to do the recording for you. If you wanted to record your iPhone's screen without an external device, there were unofficial apps you could use, like AirShou, but they required complicated installations. Now, in iOS 11, iOS 12, and iOS 13, Apple has an official, native screen recording tool.
Put yourself in Google's shoes: You know that business is becoming increasingly mobile, but the mobile operating system you maintain is wide open by design, and it's garnered legions of loyal fans that love to explore and exploit every aspect of it. There's a clear conflict of interest developing.
A robust appetite for imported foods is leading to increased disease outbreak in the US. Despite the locovore and slow food movements, America's demand for foreign foods is picking up. According to a study published in the journal of Emerging Infectious Diseases, demand for imported fresh fruits, vegetables, and seafoods has jumped in recent years.
Marijuana is legal to use for medical purposes in 28 states and the District of Columbia, but the quick development of this new industry could have left some regulation issues in the lurch.
Exposed to hormones, pharmaceuticals, and other chemicals, the beautiful wild fish in Canada's Grand River have taken on some pretty odd characteristics—they're turning into females. A long-term study suggests using bacteria to manage polluted water could turn the tide for feminized fish.
The search for the causative agent of colony collapse—the mass die off of honey bees throughout the US and Europe—has escalated with increasing confusion lately. Everything from pesticides and stress to viruses and mites have been implicated, and some researchers think that many of these environmental factors work together to take down hives.
The presence of certain bacteria can indicate whether the vaginal tract is healthy or not. It could also impact the likelihood of acquiring certain sexually transmitted diseases, like HIV, a new study suggests.
Bacteriotherapy sounds a lot more amenable of a term than "fecal transplant," yet they're both treatments that use bacteria itself to cure or treat infections. Fecal transplants, specifically, are an up-and-coming treatment option for a potentially deadly and difficult-to-treat diarrheal infection called Clostridium difficile.
One of the big hurdles when equipping vehicles with sensors for autonomous driving is the cost. For example, the Light Detection and Ranging (LiDAR) sensors that power many versions of self-driving car technology are pricey, currently ranging from around several thousand dollars up to $85,000 per sensor—and vehicles often need multiple sensors to see enough of what is going on around them to drive safely.
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.
Last week it was announced that Waymo, the former Google Self-Driving Car project, had graduated from Alphabet's X innovation center. This graduation had been in the cards for many months with senior members of the project team and X hinting that it would be soon.
I've seen my fair share of heartbreaks when it comes to used phones. As a repair tech, I often had to try and help out customers who bought used handsets which turned out to be useless, either because it was stolen or not working on their carrier's network. More often than not, there was very little I could do. To help you from being stuck in the same situation, here are some tips to prevent you from getting scammed out of your hard earned money when buying a used handset.
The new Samsung Galaxy S8 and Galaxy S8+ phones were announced on March 29 at the Samsung UNPACKED 2017 event. Preorders start on March 30 for the Korean tech giant's latest flagships, and sales officially begin in the US on April 21. Samsung will need a smooth release to win back consumer trust after the Note7 mess, and it's already looking like the S8 won't disappoint.
When a new version of iOS comes out, everybody gets caught up in the craze of finding features and playing around with new functionality. But this generally leads to a lack of coverage on the finer aspects of the update—things like bugs, minor tweaks, and pain points that users discover along the way.
Pokémon GO, the global augmented reality game that's brought fans out of their homes to catch Pokémon across the planet, has brought about plenty of real-world positives. Unfortunately, when players get power hungry and start taking game hacks too far, we all get a little screwed—both digitally and in real life.
Several technologies seek to change the way we perceive our reality, whether that involves entering a virtual world, augmenting an existing one in a realistic and interactive way, or somewhere in-between.
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.
Welcome back, my hacker novitiates! If you have been following this new Snort series, you know that Snort is the world's most widely used intrusion detection/protection system. Now a part of the world's largest network equipment company, Cisco, it is likely to be found everywhere in one form or another. This makes a compelling argument for learning how to use it, as it will likely be a necessity in any security-related position.
Running out of any shower necessity is just a temporary annoyance, but it always seems worse when it's an empty can of shaving cream or gel. Sure, you could dry shave or use whatever liquid toiletry item is in hands reach, but if you want a truly smooth shave without irritation, you'll want to try one of the following alternatives. Some of them might even work better than your can of Barbasol or Skintimate.
As Android's official app provider, the Google Play Store is packed with thousands of useful programs. But Google's terms of service is extremely restrictive, which means that countless apps simply don't qualify to be hosted on the Google Play Store.
I'm starting to wonder if the people at Boston Dynamics have ever watched a Terminator movie. Not just because the robotics company with the oxymoronic name develops machines that are able to move around environments with animal- and human-like agility, but because the people testing them seem to take such joy in openly antagonizing their creations. It's one thing to tempt fate by creating superhuman robots that could potentially end mankind. You've reached a whole new level of hubris when yo...
There was lots of new tech to check out at CES 2016, but you could argue that the majority of the big-ticket items weren't the most unique things in the world. Thankfully, there were a few innovative, unconventional ideas on display, and here are some of our favorites.
Chestnuts are roasting on an open fire, which can only mean one thing: Christmas is nearly here. It's the time of year we're supposed to spend with family and friends, but usually we spend it stressing out over what to buy everyone on our list without going over budget, or shopping for decorations or holiday-friendly food items.
Making sure you have the best gallery app available for your Android device used to be as easy as just installing QuickPic. But late last year, Android's top photo-viewing app was sold to a company who is notorious for permission spamming, so QuickPic quickly lost everyone's approval.
As many of you know, processor's clock frequency improvement got stuck in about 2003, causing the origin of multicore CPU (and other technologies). In this article I'll introduce you on how to run code simultaneously in various processors (I suppose that all of you have a multicore CPU). When you write code without any parallel directive, it only executes in one CPU at the same time (see it below). OpenMP make simple to work with various cores (if not with all of them) , without so much heada...
Mostly all hackers like to have a laugh. We like to have fun! We like to troll. And maybe, even cause some havoc once in a while. But, while we do this, we must always stay in the line of the law.
Welcome back, my fledgling hackers! In this series, I am trying to develop your knowledge of digital forensics, which is valuable whether you're choosing a career in it or just want to know how your hacker activity can be traced. Few professional digital forensic investigators have a hacking background, but the best ones do.
Whether you're just getting your first Android, or are already on your fifth annual cycle of picking up the latest flagship, there is always the question of what to do after booting up your device for the first time.
Microsoft's new voice-enabled virtual assistant, Cortana, is a lot like a blend of Siri's personality and Google Now's predictive capabilities—but the best part is it's baked right into the taskbar in Windows 10.
Welcome back, my rookie hackers! So many readers come to Null Byte to learn how to hack Wi-Fi networks (this is the most popular hacking area on Null Byte) that I thought I should write a "how-to" on selecting a good Wi-Fi hacking strategy.
