Welcome back, my tenderfoot hackers! As you know, DNS, or Domain Name System, is critical to the operation of the Internet. It provides us with the ability to type in domain names such as www.wonderhowto.com rather than the IP address. This simple service saves us from having to memorize thousands of our favorite website IP addresses. Instead, we simply type in a domain name to retrieve the website.
Fish is delicious, and as the Harvard School of Public Health points out, incredibly good for you. There are many studies that show regularly consuming a couple of servings of fish per week can help prevent heart disease and may well reduce your chances of stroke, depression, and getting Alzheimer's. After all, there's a reason why fish is called "brain food."
Welcome back, my greenhorn hackers! My preference for Linux as a hacking platform is well documented, and I have even created a series of tutorials to train new hackers. Without being proficient in Linux, you can't really call yourself a hacker.
When life gets boring, you change it up. A little tweak in your schedule goes a long way in making your existence fresh again, and it could be anything from putting on deodorant to seeing a movie with someone you don't know. The more flexible you are in life, the more dynamic it should be.
Halloween is only a few short weeks away, and most people are scrambling to get their costumes together before the big night. The secret to a great getup is all in the details, and including your pet in the fun can be exactly what you need to take your costume to the next level.
With over a million apps available in the App Store, you'd think that Apple would have come up with a better way to organize them on your iPhone.
Welcome back, my fledgling hackers! Nearly every commercial enterprise worth hacking has an intrusion detection system (IDS). These network intrusion detection systems are designed to detect any malicious activity on the network. That means you!
When I left off on our last hack, we had hacked into the ubiquitous Windows Server 2003 server by adding ourselves as a user to that system so that we can return undetected at any time. The problem with this approach is that a sysadmin who is on their toes will note that a new user has been added and will begin to take preventative action.
Your closet is an area that holds important things such as keys, glasses, clothes and shoes. However, for some reason, it's always messy. Why is this? I know my closet is messy because I don’t have a lot of time to sit down and organize every little thing in there. I have never really even given much thought into organizing it.
Organizing a convention or conference requires many moving parts and tireless effort by passionate planners and volunteers. Get help planning a convention in this free business organization video series.
If the importance of augmented reality and VR hardware to Facebook's future wasn't already clear enough, a shake-up in the executive ranks at the company has made it as clear as smartglasses lenses.
Linux is a diverse and powerful operating system that virtually every IT professional must learn and know well. Whether you realize it or not, you have likely already used a Linux device, and learning to design things for it is a key step in any Data Science career path.
While there are completely legitimate reasons to use Bitcoin, it's also used by terrorists, drug dealers, and other shady people that need to be investigated. That's where SpiderFoot comes in, which has a command-line interface to search for Bitcoin wallet addresses on a website and query the balances associated with them.
The amount of information we see on a daily basis is overwhelming. Then there's all the data we never even see. If your career depends on making sense of all of this information, you need to understand the programs that do the heavy lifting.
No longer strictly relegated to the realm of science fiction shows and novels, artificial intelligence can be found behind important technologies that are driving innovation throughout the world. From space exploration and self-driving cars to data science and marketing algorithms, AI is the driving force behind many technologies that are moving humanity forward.
It is well documented that what you say and do online is tracked. Yes, private organizations do their best to protect your data from hackers, but those protections don't extend to themselves, advertisers, and law enforcement.
Wi-Fi networks come in two flavors: the more common 2.4 GHz used by most routers and IoT devices, and the 5 GHz one offered as an alternative by newer routers. While it can be frustrating to attack a device that moves out of reach to a 5 GHz Wi-Fi network, we can use an Alfa dual-band adapter to hack Wi-Fi devices on either type of network.
MIT artificial intelligence researcher Lex Fridman recently asked SpaceX and Tesla founder Elon Musk possibly the best question he's ever been asked: What would he ask a hypothetical AGI system (an AI system with human-level intelligence and understanding) if he only had one question?
It's been said time and time again: reconnaissance is perhaps the most critical phase of an attack. It's especially important when preparing an attack against a database since one wrong move can destroy every last bit of data, which usually isn't the desired outcome. Metasploit contains a variety of modules that can be used to enumerate MySQL databases, making it easy to gather valuable information.
The words of three of tech's most important executives in the last 48 hours are providing some valuable insight into the near term future of augmented reality and the cloud infrastructures that support it.
Although the Health app mostly focuses on fitness, Apple has slowly added features to help with other aspects of well-being, including hearing. In iOS 13, there's now a headphones volume tracker in Health that monitors audio levels and lets you know when your music, podcast, movie, or whatever else is too loud.
Businesses leave paper trails for nearly every activity they do, making it easy for a hacker or researcher to dig up everything from business licenses to a CEO's signature if they know where to look. To do this, we'll dig into the databases of government organizations and private companies to learn everything we can about businesses and the people behind them.
Reconnaissance is one of the most important and often the most time consuming, part of planning an attack against a target.
Things are a bit more organized in Apple Reminders, so the cluttered mess that it once was is no more in iOS 13. The slapped-together feel in older iOS versions was the main reason I never used it that much, but the updated version for iPhone has finally got me hooked.
Particular vulnerabilities and exploits come along and make headlines with their catchy names and impressive potential for damage. EternalBlue is one of those exploits. Originally tied to the NSA, this zero-day exploited a flaw in the SMB protocol, affecting many Windows machines and wreaking havoc everywhere. Here, we will use EternalBlue to exploit SMB via Metasploit.
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?
Microsoft Office files can be password-protected in order to prevent tampering and ensure data integrity. But password-protected documents from earlier versions of Office are susceptible to having their hashes extracted with a simple program called office2john. Those extracted hashes can then be cracked using John the Ripper and Hashcat.
Influencers of augmented reality demonstrate expertise in their fields and outline a strong vision for the future that they evangelize to others. They help define the direction of the industry and identify others who foster and create innovation in the field.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Using the Mentalist, we can generate millions of likely passwords based on details about the target.
Starting your morning right is an essential first step to a productive day. Whether you're running late, rushing to catch up on the day's news, or lagging behind with early emails, little hiccups like these can have a trickle-down effect and ultimately ruin your day. Like with many problems, though, your smartphone can help.
Mobile phones are not only essential for work and communication, they're quickly becoming an integral asset to our health. Your iPhone can store valuable data about fitness, nutrition, heart health, and so much more. And since iOS 11.3, your iPhone can even import a list of allergies, medications, immunizations, hospital visits, and other health information from your doctor or hospital.
So much information exists online that it's easy to get lost in data while researching. Understanding the bigger picture can take a lot of time and energy, but narrowing the question to one that's easy to answer is the first step of any investigation. That's why analysts use open-source intelligence (OSINT) tools like Maltego — to help refine raw data into a complete understanding of a situation.
Some of us woke up at the KRACK of dawn to begin reading about the latest serious vulnerability that impacts the vast majority of users on Wi-Fi. If you weren't one of those early readers, I'm talking about the Key Reinstallation Attack, which affects nearly all Wi-Fi devices.
On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
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.
Young girls, especially those who live in areas where HIV is epidemic, like sub-Saharan Africa, are particularly vulnerable to becoming infected with HIV. A vaginal ring containing the antiviral agent dapivirine has been shown to decrease the chance of developing HIV-1 in adult women over 21 and now in the first step for use in adolescents, the ring has been shown to be safe and well-tolerated in that younger age group.
DownToDash, an app from an NYC-based startup, connects students to other students who want to hang out the same way they do. The social networking app has gained increasing popularity since its launch in October 2016 and looks ready to become even more available. The app was founded by Sama Jashnani and Anuja Shah, both recent students themselves.
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.
The office of your physician, or your local hospital, is where you go when you need medical care. But it could also be where you could pick up a life-threatening infection.
