When joining a new network, computers use the Address Resolution Protocol to discover the MAC address of other devices on the same network. A hacker can take advantage of ARP messages to silently discover the MAC and IP address of network devices or actively scan the network with spoofed ARP requests.
Traveling abroad can be a hassle. Between the flight, hotels, food, and the languages barriers, it can be a lot to manage. There's one tool you have that can help with all of this — your smartphone. Fortunately, nowadays, you don't have to change your carrier to continue using your phone.
Slack recently released a dark mode for its Android and iOS apps, and for the most part, it works great. Super dark gray backgrounds and light gray fonts, which is much easier on the eyes than blinding white backgrounds and black text. But there's one thing that is not affected by the new night mode setting — your sidebar.
Your Instagram feed is jam-packed with interesting and lively photos, videos, and stories that largely offset the iOS app's comparatively bland user interface. If the interface's dull colors have always bothered you, you can splash on some much-needed color to better reflect your personality and tastes.
ARP spoofing is an attack against an Ethernet or Wi-Fi network to get between the router and the target user. In an ARP-spoofing attack, messages meant for the target are sent to the attacker instead, allowing the attacker to spy on, deny service to, or man-in-the-middle a target. One of the most popular tools for performing this attack is Ettercap, which comes preinstalled on Kali Linux.
Two-factor authentication (also known as 2FA) adds a necessary additional layer of security to your username and password in many important apps. On Instagram, 2FA requires you to confirm it's you attempting to log in, with a special code sent to you via text message. Enter the code and you're in ... but what happens when you need to log in and don't have access to your phone?
Expressing yourself during chats is much easier these days thanks to the steady rise of emoji. Now, products like emoji Minis for Gboard are taking the craft to an interesting yet familiar new level. With emoji Minis, you can automatically create stickers based off your own face. From there, you can further customize the stickers by adding key features such as glasses, earrings, and facial hair.
Overall, iOS is more impressive than ever with its stability enhancements, security tools, suite of apps and services, and intuitive user interface. With each passing update, things just get better and better for iPhone users. But don't think for a second that this is all because of Apple's genius — many of these features were at least partly inspired by tweaks made by the jailbreak community.
Apple's iOS 12 has finally landed. The big update appeared for everyone on Monday, Sept. 17, and hiding within are some pretty amazing augmented reality upgrades for iPhones, iPads, and iPod touches. We've been playing with them ever since the iOS 12 beta launched in June, and here are the things we learned that you'll want to know about.
The iPhone XR offers a discounted experience compared to the expensive iPhone XS and XS Max. However, that lower price tag comes with some caveats, such as "Haptic Touch" in lieu of 3D Touch. If you think these two "touch" features are the same, think again. Before you get an iPhone XR, you'll want to know all the excellent features 3D Touch you might miss. Can you go without them?
If you've been getting that "Please update from the iOS 12 beta" alert continuously in iOS 12 public beta 9, Apple just issued a fix for it Friday, Aug. 31, with iOS 12 public beta 10 — just in time for Labor Day weekend. This marks the second update this week as dev beta 11 and public beta 9 were released on Monday. It's also just one day after Apple announced its Sept. 12 event.
In a surprise twist, Apple released iOS 12 public beta 8 to software testers on Thursday, Aug. 23, right alongside iOS 12 dev beta 10. The release comes as a bit of a shock, as the company released iOS 12 public beta 7 just three days earlier. The official build of iOS 12 now feels closer every day.
We're nearly there — Apple released the seventh iOS 12 beta to developers Monday, August 13. While not totally unexpected, beta testers understand the struggle of predicting the next update, as Apple has switched haphazardly between two-week, one-week, and irregular release schedules for both the developer and public betas.
For the second time in a row, Apple pushed out a new iOS 12 developer beta on a Monday, and for the first time this round, they've done it only one week after the last one. While the August 6 release of iOS 12 developer beta 6 doesn't contain a wealth of updates, there are still a few things you'll want to know about.
As the official release of iOS 12 nears closer each day, Apple continues to update its betas. The company released the fourth beta of the upcoming software to developers Tuesday, July 17, exactly two weeks after the release of the third developer beta which came out just a few days before the second public beta.
Sometimes we need to share screenshots, but don't want to reveal the entire screen. This usually requires some editing that isn't typically easy to do on a smartphone. BlackBerry recognized this issue and created a tool called Redactor that makes it easy to hide your data before sharing.
Apple released the third beta of iOS 12 for developers on Tuesday, July 3. The update comes exactly two weeks after the release of the second developer beta, which introduced a variety of fixes as well as new issues, and just one week after the release of the public beta. Public beta testers received this iOS 12 update on Thursday, July 5, labeled as public beta 2.
Right on the heels of the iOS 11.4.1 beta 3 release, Apple pushed out iOS 12 beta 2 to registered developers on Tuesday, June 19. Public beta testers received the same version, labeled as iOS 12 public beta 1, six days later on Monday, June 25. Last year, the iOS 11 public beta opened up just five days after the release of iOS 11 developer beta 2, so iOS 12 is pretty much right on track in that regard.
Apple's doubling down on AR features in iOS 12 and iOS 13. The iPhone's augmented reality framework got a major overhaul with ARKit 2 and ARKit 3, and that's just the tip of the iceberg. While the updated API tools will help developers make better interactive apps, there's another new AR feature that regular users will enjoy: Animoji in FaceTime.
Apple's next big developer event happened on June 4, and it was the first glimpse of iOS 12 that anyone's seen. While there were lots of rumored features to be unveiled at WWDC 2018, Apple concentrated mostly on squashing bugs and making iOS work as seamless as it did years ago. Still, we had hoped that Apple would have added these features in iOS 12, but only a few made the cut.
While there are at least five cool things coming in iOS 11.4, they may not be enough to get you to install the iOS 11.4 beta on your iPhone. Since its initial beta release at the start of April, there have been plenty of known issues and user-reported bugs to deal with. While bugs are to be expected with a beta, you may want to read these before installing this one on your iPhone.
The iOS App Store is a big place, offering over two million applications in total. However, there are actually some apps you can and should install on your iPhone that the iOS App Store doesn't include. And no, these apps do not require any difficult jailbreaking or complicated sideloading techniques — they are really simple to install.
It is finally happening. After not having a major update since August of 2016, HoloLens owners everywhere will soon get a number of new features added to their devices. At least if they are members of the Windows Insider program.
Every dollar that comes your way is a blessing, especially when it comes to trading in the volatile world of bitcoins. Thankfully, Coinbase rewards you for sending much valued customers their way, giving you more money to feed your cryptocurrency trading needs.
While iOS 11.3 doesn't have as many new features as iOS 11.2, there's still a lot to love about Apple's latest update for iPad, iPhone, and iPod touch, even if some of the best features we were expecting didn't make the cut.
Apple just pushed out iOS 11.2.5 beta 7 today for iPad, iPhone, and iPod touch to both developers and public beta testers. On Wednesday, Jan. 17, beta 6 was released, and there were two betas the previous week. With Apple promising a patch for "ChaiOS" next week for everyone, it's like iOS 11.2.5 will be that update.
If you used Touch ID on an iPhone before, all you had to do to install apps and games from the App Store was rest your fingertip on the Home button. On the iPhone X, there's Face ID instead, and Apple has included on-screen instructions to help everyone adjust to the lack of Home button. Still, those instructions may not be working for you, but the solution is as simple as a misinterpretation.
Any internet user will need to download files eventually, and most simply have faith that what they are downloading is trustworthy. This doesn't give much clarity into the contents of the file, but if the file's author published the original checksum, comparing it to the SHA-256 hash of the downloaded file can ensure nothing was tampered with.
Instagram is a great platform to share photos and videos with the world, but sharing with smaller groups is near impossible. You can directly message pictures, stories, or post links to friends, but that only works for one person at a time or in group chats you create. To share your content with a small group of people you care about the most, you'll want to use the "Close Friends" list.
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.
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.
Apple's iOS 11 is finally here, and while they showed off several of the new features it brings to your iPhone, iPad, and iPod touch back at WWDC 2017, they've only just touched the surface of what iOS 11 has to offer. There are a lot of cool new (and sometimes secret) features to explore, so we've collected them all here for you.
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.
Despite a rocky start with plenty of feature disparity, the Google Assistant now provides a pretty consistent experience regardless of what device you're using it on. Be it Android, iPhone, or Google Home, the AI behind the Assistant is virtually identical — including its quirky commands and funny responses.
If the all the fingerlike projections in our gut were flattened out, its surface area would be 100 times bigger than our skin's. It's so large that the actions of just a small part of it can impact our health. A new research study has found that enterochromaffin cells in the intestinal lining alert the nervous system to signs of trouble in the gut — trouble that ranges from bacterial products to inflammatory food molecules.
Social media is kind of depressing. On one hand, we love knowing what's happening in the lives of others. On the other hand, everyone seems happier, better looking, and more successful than you. We're putting on a facade by posting statuses and writing comments that present the person we want others to think we are, rather than truly expressing ourselves. Yes, social media has facilitated movements and miraculous events, but let's be real. For the most part, none of it matters.
Those of us who are actively developing for the HoloLens, and for the other augmented and mixed reality devices and platforms that currently exist, are constantly looking for the next bit of news or press conference about the space. Our one hope is to find any information about the road ahead, to know that the hours we spend slaving away above our keyboards, with the weight of a head-mounted display on our neck, will lead to something as amazing as we picture it.
The keynote at this week's Vision Summit 2017, a two-day event put together by the Unity team in beautiful Hollywood, California, revealed a few new features coming to the Unity platform. They also previewed some of the beta features that are currently available for those less scared of the occasional hiccup.
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.
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.
