Many operators use elevators to control access to particular floors, whether it be the penthouse at a hotel or a server room in an office building. However, the law requires them all to have a fire service mode, which gives emergency access to restricted floors, and a hacker can use that to bypass security altogether.
As you're surely aware, your phone can be used against you. Thanks to our cameras and microphones, a clever hacker can obtain access to your device and invade your privacy. But spying isn't limited to just these two sensors — gyroscopes, proximity sensors, QR codes, and even ads can be used to paint a very clear picture about who you are and what you're currently doing.
Certain contacts on my iPhone have special ringtones so that I know exactly who's calling or texting without looking at my screen (like Adele's "Hello" for all my exes). But when my phone is silenced and tucked away in my pocket, these contact-specific ringtones can't really help me out. Luckily, there's something else that can—custom vibration patterns.
Learning Chinese is hard, but it can be a lot easier with the help of a few great apps. As a native English speaker who's currently living in China, this is a process I've recently gone through. After playing the field, here are the three apps I personally think will help you the most with your Chinese learning adventure.
Ports allow network and internet-connected devices to interact using specified channels. While servers with dedicated IP addresses can connect directly to the internet and make ports publicly available, a system behind a router on a local network may not be open to the rest of the web. To overcome the issue, port forwarding can be used to make these devices publicly accessible.
Developing an imperceptible lie is difficult, especially when you're lying right to someone's face. Thanks to smartphones, getting people to trust you is now easier than ever. You can craft a lie in seconds and hit send, all without ever seeing their untrusting faces.
Every year, Black Friday gets a little more insane. People get up at ungodly hours, wait in lines forever, and get into some of the most ridiculous fights you've ever seen. All in the name of saving some cash. Everyone loves saving money, but without a game plan, you could end up missing all the good deals and going home with nothing. Luckily, the Internet is here to take some of the stress out of holiday shopping. With these sites and apps, you can find out about all the best deals before yo...
Google is an incredibly useful database of indexed websites, but querying Google doesn't search for what you type literally. The algorithms behind Google's searches can lead to a lot of irrelevant results. Still, with the right operators, we can be more exact while searching for information that's time-sensitive or difficult to find.
Welcome back, my tenderfoot hackers! I have written many tutorials on hacking using Metasploit, including leaving no evidence behind and exploring the inner architecture. Also, there are my Metasploit cheat sheets for commands and hacking scripts.
YouTube is the third most popular website in the world, after Google and Facebook. Millions of subscriptions happen each day on YouTube, with over 800 million unique users visiting each month. In that timespan, roughly 4 billion hours of video are watched, with 72 hours of video uploaded every single minute.
For many of us, our work phone and our personal phone are one and the same. Just any old phone isn't going to cut it when you need to meet a deadline — a phone with built-in features that make it easier to get things done is almost a must.
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.
While iOS 11 is ready to take over your iPad, iPhone, and iPod touch, let's take a step back and check out all of the new features that iOS 10 brought to the public when it was released to everyone in Sept. 2016.
This daring docu-drama explores the esoteric underground of hard-cider brewing. This fast paced thriller is sure to captivate the mind, and leave you on the edge of your seat. OK, it's just a video shot with a 3mp Cannon digital camera on video mode and edited with some lousy free software. There are two different methods used to make this hard cider. 5 gallons of fresh cider with a starting specific gravity of 12 were pitched with White Labs liquid English Cider Yeast. This should yield arou...
If you use the Notes app on your iPhone and haven't updated to the newest software yet, you're missing out on some pretty valuable upgrades that improve smart folders, note security, collaboration, and more. So what are you waiting for?
One of WhatsApp's best features is being able to change the default wallpaper for all chats. There's no reason to stick to the default WhatsApp backgrounds when you can be texting over an image of literally anything. In a newer WhatsApp update, you can go a step beyond that by setting custom wallpapers for individual chats, personalizing every text thread you have.
Messages is arguably the most important app on your iPhone, which is why it's always exciting when Apple pushes out new features for it. With the iOS 14 update, there a few critical changes as well as interface improvements and customization options that make the experience even more personalized than it already was.
Sometimes you may need to send a message out at a specific time. Say a thought strikes you late at night, but you don't want to wake anyone up. You could do this by waiting to sending it at your desired time — or, you could schedule your message at a precise time.
It's finally out. After months of testing, iOS 13 is available to install on your iPhone, which means over 200+ new features you can use right now. The update, released on Sept. 19, can be installed over the air or from a restore image using iTunes in macOS Mojave and older or Finder in macOS Catalina. Ditto for the 13.1 update issued on Sept. 24.
The art of privilege escalation is a skill that any competent hacker should possess. It's an entire field unto itself, and while it's good to know how to perform the techniques involved manually, it's often more efficient to have a script automate the process. LinEnum is one such script that can be incredibly useful for privilege escalation on Linux systems.
The most essential part of a healthy lifestyle is managing your diet — after all, what would be the point of a daily workout regimen if you were eating junk food? Thankfully, Samsung Health makes it easy to record your calorie and nutrient intake to get a clear picture of your dietary habits and how you can make them better.
Nmap is more powerful than you know. With a few scripts, we can extend its functionality beyond a simple port scanner and start to identify details about target servers sysadmins don't want us to know.
When BlackBerry made the move to Android OS, they were aware of the limitations it presented. Unlike with BB10, they didn't create the operating system and would have to deal with the vulnerabilities already included. As a result, they added numerous security enhancements, and at the heart of this is DTEK.
Ransomware is software that encrypts a victim's entire hard drive, blocking access to their files unless they pay a ransom to the attacker to get the decryption key. In this tutorial, you'll learn how easy it is to use the USB Rubber Ducky, which is disguised as an ordinary flash drive, to deploy ransomware on a victim's computer within seconds. With an attack that only takes a moment, you'll need to know how to defend yourself.
In the "Do Not Disturb" menu in your iPhone's settings, you can choose to allow phone calls from everyone, your favorites, or specific groups. However, this does not apply to text messages, only phone calls, so there's no way to get vibration or sound alert for messages from select contacts — but that doesn't mean there isn't a way.
We are totally buggin' about Pinterest's update to their Lens. I know, I had to.
Snapchat has already found a compelling way to create advertisements in augmented reality with their branded filters, but they continue to experiment with new ways to monetize the bridging of the real and digital worlds. Their latest idea, which requires users to "snap" an image to unlock content, could succeed where QR codes haven't.
In Pokémon GO, having an in-depth understanding of your Pokémon's stats and abilities is crucially important to becoming a better player. Not all Pokémon are created equal; as such, it's critical that you look at each of your Pokémon—even duplicates—with a keen eye.
Welcome back everyone! It's been quite a while hasn't it? Today we're going to kick off the second part of the Python training series by introducing modules. We'll start off by explaining what a module is and we'll give an example. So, let's get started!
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.
An app called Launcher was released for iOS 8 last September that let users open any installed app directly from a widget in the Notification Center pull-down. For some reason, Apple didn't take too kindly to this and banned Launcher from the iOS App Store just a few days after its release.
If you've ever owned an HTC device or anything in the Nexus line, odds are, you have typed the word "fastboot" into your command line at one time or another. That said, odds are, you have only just barely scratched the surface of what this handy little Android tool can do. Let's take a deeper look.
Welcome back, my hacker noviates! In a recent post, I introduced you to Shodan, the world's most dangerous search engine. Shodan crawls the globe from IP to IP address, attempting to pull the banners of each web-enabled device and server it finds.
Apps that have no business accessing the internet can share your location, device ID, and other personal information with potentially malicious data snatchers. If you're connected to the internet on your Nexus 7 tablet, you're a potential target for cyber threats.
For my money, one of the greatest improvements brought about from the smartphone revolution is the advent of visual voicemail. No longer do we have to slog through dial menus or trudge through every single message to get to the next. We can just look at our messages, right there on our screens, organized neatly like emails or text messages.
You can add a timestamp to any YouTube video in just a few clicks from the desktop website on your computer but not from YouTube's iOS or Android app. Until YouTube adds a "start time" when sharing videos from the mobile app, you'll have to use one of these workarounds on your phone or tablet.
Whether you've celebrated multiple cake days or you're just now getting your feet wet with Reddit, it's a rite of passage to choose your preferred smartphone client. Quick spoiler: Your best option most certainly is not the official Reddit app.
If you're on the hunt for a profitable side-gig, or even a completely new way to to make money, you'll want to take a look at Upwork, a leading freelancing platform that connects skilled freelancers with clients from all over the world.
There's actually more to the dialer screen on your OnePlus than meets the eye. Besides its obvious purpose of calling people, there's a vast array of secret codes that you can input to troubleshoot your device, in addition to revealing important information, making anonymous phone calls, and so much more.
Analysis of photographs and social connections can be a huge component of social engineering. Understanding who a person is, as well as who they know, can establish links within a company. This information could be used by hackers to execute elaborate social engineering attacks.
