The public leaks of NSA tools and information have led to the release of previously secret zero-day exploits such as EternalBlue, which was used in the notorious WannaCry ransomware attack. Despite multiple patches being released, many users have failed to update their systems, so many devices are still vulnerable to these now-public attacks.
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.
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.
As the fish farming industry struggles to become more environmentally friendly, it just gained another problem. Fish food loaded with antibiotic-resistant genes.
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.
The bacteria in our gut — a community called the gut microbiome — have been in the spotlight a lot lately. What we're learning about how our intestinal bacteria adapt and grow with our bodies could help athletes perform better, according to researchers starting a company focused on creating probiotics that mimic athletes' microbiomes.
Blowing dust and fungal spores are creating a public health problem that could be just a slice of what's to come with climate change.
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...
So cute, so furry, and so chock full of parasites. While raccoons are fun to watch, they are neither friendly nor clean — and they can make you sick in more ways than one.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
When you have an infection, a doctor prescribes antibiotics to make the bacteria that causes it disappear. Sounds like a good idea, but the disappearance of microorganisms that have inhabited humans for millennia could be driving rising numbers of serious illness and debilitating conditions.
Sharing your Wi-Fi password is like giving an unlimited pass to snoop around your network, allowing direct access even to LAN-connected devices like printers, routers, and security cameras. Most networks allow users to scan and attempt to log in to these connected devices. And if you haven't changed the default password on these devices, an attacker can simply try plugging them in.
The next time you suffer a cut or abrasion, think twice before you reach for the Neosporin. It's time, and mom, tested — you get a cut, you wash it carefully, then apply some triple-threat antimicrobial ointment. You may or may not slap on a band-aid. We won't cover it here, but so that you know, covering the wound with a sterile dressing or band-aid is a good idea.
When you first set up an iPhone, you'll be prompted to create a six-digit passcode to unlock your screen and access certain system settings. If you skip this step, you can always go back and create one, which we highly recommend. Without a passcode, everything on your iPhone is accessible by anyone who gets their hands on it — nosey friends, hackers, thieves, local law enforcement, the FBI — and you don't want that, do you?
Killing more than 29,000 people each year, infection with Clostridium difficile (C. diff or CDI) is the most common healthcare-associated infection in the US. In a disturbing development, new research reveals recurring cases of the infection are soaring.
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.
Tell the truth. The bat picture creeps you out. You are not alone. But in reality, bats truly are some of our best friends. They gobble thousands of disease-spreading bugs a night. But they also carry viruses that can be deadly to humans. So, bats — friend or foe?
As a part of the already crowded field of diseases transmitted by ticks, you may not know the disease babesiosis, a dangerous infection caused by a parasite that infiltrates blood cells.
Like humans, cats can suffer infections caused by ticks, and too often, the disease is fatal. Learn about tickborne diseases that affect cats and what you can do to protect Fluffy from an untimely demise.
Apple's been hard at work adding new features and finishing touches to iOS 11, and there's evidence of it everywhere. But there's one place where these changes are more noticeable than perhaps anywhere else — Safari.
In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
One thing that I got more and more excited about as we got closer and closer to the Microsoft Build 2017 developers conference was finally learning about the new Acer Windows Mixed Reality head-mounted displays (HMD). Brandon Bray, Principal Group Program Manager at Microsoft, had teased us a few weeks earlier at the Vision Summit event in Los Angeles, California, and said there would be a lot more information at Build. Fortunately for us, he was right.
Microbial cells can improve the functionality of clothes in creative and useful ways, including cooling us down during a workout or making clothing glow for better visibility.
While it is easy to create and maintain your compost pile, you can enjoy it more knowing a few basic tips.
Think of the coolest, most unique way to create art that you can. Got it? Now think about creating that art out of living things.
While no longer native to the United States, hospitalization from malaria occurs in this country more than most would believe. Why is that, and what can you do to protect yourself when you travel abroad to regions where malaria is active?
In the tech world, when you're a small startup going up against the Goliaths and their massive marketing budgets, you're forced to find and produce something almost magical to help your product stand apart from the rest. And that's exactly what Occipital Inc. has done with their Bridge headset.
When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.
The beauty of southern Europe won't protect it from invasions of disease-carrying ticks and mosquitoes—in fact, the Mediterranean climate and landscape may be part of the reason the bloodsuckers are expanding there, bringing unique and terrifying diseases in their wake.
It won't come as a surprise to hear that your cell phone, tablet, and laptop are loaded with bacteria and other organic material. While most of these bacteria are harmless, there are good reasons to reduce the capability of your mobile devices to infect you—or other people.
If the rumors are right, Microsoft has decided to cancel the second version of the HoloLens, and they will instead move onto version three of their mixed reality headset. In the latest report, Thurrott's Brad Sams states that the expected release date of this new Windows Holographic device wouldn't be until 2019, a long two years away for those of us putting full effort into HoloLens app development.
Prion diseases are a group of infectious brain diseases that causes extensive tissue damage, resulting in sponge-like spaces in brain tissue. Prions include Creutzfeldt-Jakob disease in humans, bovine spongiform encephalopathy (often called mad cow disease), and chronic wasting disease in hoofed ruminant mammals.
What's in a sneeze? Quite a lot—dirt, mucus, and infectious germs—it seems. And sneezing the right way can reduce the germs you share with neighbors.
General Motors acquired Cruise Automation in March 2016 for a reported $1 billion (well, at least $581 million). GM President Dan Ammann made a point of being in the press release photograph with Cruise founders Kyle Vogt and Daniel Kan (see photo below). On January 19, 2017, Vogt posted on Twitter: "Took GM Pres. Dan Ammann for a ride in a Cruise AV."
To shine light on the future of the relationship between humans and viruses, a team of researchers from the University of Oxford looked into the dim and distant past.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
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.
Even when no one is in your kitchen, it is crowded. The refrigerator, sink, and counters are all covered with microbes that are just hanging around. They are inadvertent remnants from the raw chicken you used in that recipe last night, brewing a bacterial cocktail in your Nespresso machine, or just growing their merry little colonies on your leftovers.
If your phone has an unlocked bootloader, you can use Fastboot commands to flash factory images. That may sound like a bunch of technical jargon, but when it comes down to it, this is the best method for updating a rooted device, fixing a bricked phone, reverting to stock, or even getting new Android updates before everyone else.
We're nearly done getting our Mac set up for hacking. If you haven't checked out previous tutorials, I'd recommend you do so first before diving right into this one.
