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.
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.
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.
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.
Six people have died from fungal infections in Pittsburgh hospitals since 2014—that fact is indisputable. The rest of the situation is much vaguer. A lawsuit has been filed against the hospitals on behalf of some of the deceased patients, alleging that moldy hospital linens are to blame. While the lawyers argue over who's at fault, let's look at how this could have happened.
Jostled in the airport, someone is coughing in line. The air looks empty but it is loaded with microbes that make their way into your body. You get sick. You give it to your family, and that's pretty much it. But what if you were so contagious that you spread it to your entire community and beyond?
Ask anyone that works on the development of driverless vehicle technology and there is a very good chance that AutonomouStuff will have supplied something to their project.
When Kaci Hickox, a Doctors Without Borders nurse, returned to New Jersey from working with Ebola patients in West Africa in 2014, she was surprised by her reception. Instead of a quiet return to her home in Maine after four weeks on the front line of Ebola treatment, she was quarantined by the State of New Jersey in Newark. She later filed a lawsuit in U.S. District Court for violation of her civil rights, false imprisonment, and invasion of privacy.
With all of the bare-bones setup out of the way in our Mac for Hackers series, your Apple machine should be ready to run a significant amount of pentesting tools. We can pull tools from GitHub and compile them, we can pull dependencies or tools from Homebrew, we have both Python and Ruby. Everything is ready to go and now it's time to start building a toolbox on our local host.
Google is on a mission to bring a better messaging experience to Android users. We've seen them try and fail over the years with various messenger apps, but this time, they're taking a different approach by working with industry leaders to create a new messaging standard. The result is RCS Universal Profile, or simply Chat, and it's finally catching on.
If you've ever played the game of Would You Rather, you've probably been given the ultimatum between eating insects or doing something else that sounds absurd, like licking a cactus. I'm advising you to always choose the insects, and here's why:
Pokémon GO made waves as the first augmented reality game to gain popular adoption. In fact, it was so popular that it only took a few days to uncover some the benefits and serious issues with combining physical and digital worlds.
These days, there are Android apps for every budget—forgive me if that sounds like a car commercial, but that's just the way things are in the age of the smartphone and tablet. You've got apps that require monthly subscriptions, paid apps that will run you a $30 one-time installation fee, and even games that start at 99 cents, but quickly skyrocket in price with in-app purchases.
Welcome back, my tenderfoot hackers! Generally, you will want to perform a vulnerability scan before doing a penetration test. Vulnerability scanners contain a database of all known vulnerabilities and will scan your machine or network to see whether those vulnerabilities appear to exist. If they do, it is your job to test whether they are real and can be exploited.
Welcome back, my neophyte hackers! In the world of information security, the most common intrusion detection system (IDS) you will ever encounter is Snort. As you probably already know, an IDS works similarly to antivirus (AV) software on your desktop; It attempts to identify malicious software on your network and warns you of its presence.
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...
Sooner or later, you're going to come across a person at work that you don't like—or someone that doesn't like you. This can result in uncomfortable tension, insulting gossip, and a disrespectful attitude, to name just a few of the negatives. But it doesn't have to be that way. The next time you're having a workplace conflict with a particularly challenging coworker, the best thing you can do is keep your mouth shut, and here's how to do it.
Welcome back, my hacker apprentices! A you know, Mr. Robot is my favorite TV show this year, and not just for the realistic hacking. Rami Malek, the actor who plays Elliot, is incomparable in his depiction of a young man with social anxiety who is alienated from a superficial, materialistic society and wants to make a better world. I believe we will see a lot more of this actor in coming years.
