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.
Despite some early and optimistic predictions that the world would have returned to normal by now, the surprisingly stubborn and resilient coronavirus continues to upend and alter how we live our lives when it comes to working from home instead of the office.
In a world that's becoming increasingly dependent on a variety of AI and machine learning applications, Big Data reigns supreme. As the primary forces behind everything from self-driving cars and surgical robots to home automation systems and even space exploration, Big Data and AI stand at the heart of today's most important innovations.
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.
The only thing better than programming MicroPython is programming MicroPython over Wi-Fi. So once you set up MicroPython on a microcontroller and have it on its own power source, you won't need to use a data cable to connect to it whenever you need to interact with it, program it, upload files, or grab data.
Not all 5G is equal. Even if you dropped the cash on a true 5G phone and you see it's connected to 5G in the status bar, that doesn't mean you're surfing the web, streaming Spotify, and binging Netflix faster than your friends with LTE phones.
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.
Life is too chaotic to be organized all the time, but little steps in the right direction make things easier overall. File folders keep paperwork from spiraling out of control. Spice jars take the clutter out of cabinets. Storage totes keep basements neat and tidy. But to find what you're looking for faster, you need a label maker.
We've been so worried about volumetric scans possibly robbing celebrities and performers of their agency and right to control their image that, somewhere along the way, we forgot that scans may not always be necessary to produce passable holographic performances.
A lot of time can be wasted performing trivial tasks over and over again, and it's especially true when it comes to hacking and penetration testing. Trying different shells to own a target, and testing out privilege escalation commands afterward, can eat up a lot of time. Fortunately, there is a tool called One-Lin3r that can quickly generate shells, privesc commands, and more.
Phishing is the easiest way to get your password stolen, as it only takes one mistake to log in to the wrong website. A convincing phishing site is key to a successful attempt, and tools to create them have become intuitive and more sophisticated. SocialFish allows a hacker to create a persuasive phishing page for nearly any website, offering a web interface with an Android app for remote control.
Life's pretty good for iOS public testers — we get to check out new iPhone features months before the general public even knows they exist. That said, we aren't first to the party. Developers get priority during beta testing, as evidenced by yesterday's iOS 13 dev beta 6 release. It's not all bad though since Apple just released the public version of that software, public beta 5, this afternoon.
If tradition holds, we're roughly one month away from Apple's big iPhone announcement. While we're excited to see what will mainly be a significant camera upgrade, it's not all about the hardware. Apple will also release the official version of iOS 13 to coincide with the iPhone XI. Before then, however, iOS 13 needs beta testing, and developer beta 6 just hit on August 7.
When it comes to shooting games, battle royale titles like PUBG and Fortnite have come to dominate the scene, leaving other sub-genres like top-down and third-person shooters living in the shadows. They're far from irrelevant, though, as evidenced by all the great games released just in 2019 alone.
Every summer for the last 26 years, hoards of hackers have descended on the Las Vegas Strip for DEFCON, the biggest hacker conference in the US. There's a wealth of talks every season (DEFCON 27 has at least 95 scheduled), and there have been some essential topics to learn from in past discussions. We've dug through the last ten years and found the 15 most popular talks you should watch.
When you're gaming on your Android phone, does it sometimes feel "slow" and you can't figure out why? That means a drop in performance, which is when the frame rate dips, causing some noticeable stutters and lag. There's not really a way to know what's wrong unless you made the game yourself. But on the bright side, you can check any game's FPS with a simple tool.
Firewall solutions for macOS aren't impervious to attacks. By taking advantage of web browser dependencies already whitelisted by the firewall, an attacker can exfiltrate data or remotely control a MacBook, iMac, Mac mini, or another computer running macOS (previously known as Mac OS X).
An incredible amount of devices use Bluetooth or Bluetooth Low Energy to communicate. These devices rarely have their radios switched off, and in some cases, are deliberately used as trackers for lost items. While Bluetooth devices support MAC address randomization, many manufacturers do not use it, allowing us to use tools like Bettercap to scan for and track Bluetooth devices.
Smartphone videos get better and better each year. Seven or eight years ago, who would have thought iPhone and Android phones could support 4K video recording. Some phones can even shoot slow-motion at 960 fps. But no matter the resolution or frame rate, a phone's rolling shutter can make quick movements in front of the camera appear wobbly, distorted, or with artifacts.
By far the most significant development for AR in the coming months and years — the development that will drive AR adoption — will be our reliance upon the AR cloud.
Whether it's a short road trip or an 18-hour flight, our phones are now essential travel companions. No longer do we need a GPS unit, maps, cameras, camcorders, or even boarding passes. However, not all phones are created equal in this regard. Some are more suited for traveling, no matter the duration.
Among the younger generation, Roblox rivals major titles like Minecraft as one of the most popular online games out there. In fact, it's common to hear children tell new playmates to "friend me in Roblox!" so they can play together online. There's nothing inherently sinister here, but with all the online interaction, kids' safety becomes a factor.
A relay is an electrical component that works like a light switch, where it's turned on or off with an electrical signal. By connecting a relay to a Wi-Fi connected microcontroller like an ESP8266, you can build a connected switch that can be controlled from the web browser of any device connected to the same Wi-Fi network — all for just a couple of dollars.
These days, using Reddit on your iPhone is just as good, if not better, than Redditing on a desktop browser. While there's an official Reddit app for iOS, there are plenty of third-party clients that have similar features as well as custom perks to enhance the experience. But figuring out which Reddit client is best for your daily use can be a lot of work — work that we can make easier on you.
Almost every phone comes with biometric security of some sort these days, but the same can't be said of Windows computers. While fingerprint scanners are becoming increasingly common with laptops and desktops, they're nowhere near ubiquitous. Thankfully, your phone's scanner can be used as a sort-of remote authentication point for your PC.
One of the ultimate goals in hacking is the ability to obtain shells in order to run system commands and own a target or network. SQL injection is typically only associated with databases and their data, but it can actually be used as a vector to gain a command shell. As a lesson, we'll be exploiting a simple SQL injection flaw to execute commands and ultimately get a reverse shell on the server.
Waking up your Apple Watch to see "your heart has shown signs of an irregular rhythm suggestive of atrial fibrillation" might come as a shock. While your watch can send you warnings if it detects a fast or low heart rate, those messages are pretty vague, while the abnormal arrhythmia alert can downright scary. So what should you do if you receive one of these AFib notifications?
Computers all over the world rely on a program called "libssh" to use the SSH communications protocol, which allows trusted users to log in and administer computers remotely. Due to a flaw in libssh, fooling a computer into granting SSH access is as easy as telling it you already have permission. The vulnerability can lead to an attacker gaining complete control over a device.
Your Apple Watch sends you notifications from friends, family, and the apps that are important to you. Occasionally, however, the watch may scare the heck out of you with a notification warning of an abnormal, elevated heart rate. If you have no history of heart conditions, this alert might come as a shock. Why do you have a high heart rate, and what are you to do with the information?
There is no shortage of defenses against cross-site scripting (XSS) since it is so prevalent on the web today. Filters are one of the most common implementations used to prevent this type of attack, usually configured as a blacklist of known bad expressions or based on regex evaluation. But there is hope with a wide variety of techniques that can be used to defeat these filters.
One of the best ways to improve your skills as a hacker is to learn to combine different avenues of attack to achieve success. What if it were possible to get a victim to connect to our machine and execute a chosen payload on our behalf? This is indeed possible with the almighty Metasploit and the aid of a technique known as command injection.
So, you rooted your Pixel 2 or 2 XL and everything seems to be working quite well. However, a month passes, and you get a notification to install the monthly security update. Like clockwork, Google has been pushing out OTA security patches every single month for a while, but there is a new problem for you at this point — as a rooted user, you are unable to apply the update correctly.
Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
With all the controversy around the Pixel 3 XL, the regular-sized Pixel 3 might be the phone of choice for most users. Thanks to the huge boost in screen size, the little brother is now an easier pickup for those who like a bigger screen. And once more, the internals are the same, giving you the same experience as the 3 XL without the display notch.
The "controversial" Pixel. No phone in the history of Google's Pixel lineup deserves this title more than the Pixel 3 XL. For some (including myself), the design is a welcome change that embodies the modern design of 2018 flagship phones. For others, it has an ugly huge display notch that destroys symmetry.
All phones (yes, iPhones too) slow down over time. As your device gets bogged down by various apps and you begin to run out of storage, it's just an inevitability. That doesn't make it any less frustrating ... I mean, is there anything more annoying than a slow phone? My answer: No. Of course not. It's the single most annoying thing ever.
Gmail conversations, Facebook private messages, and personal photos can all be viewed by a hacker who has backdoor access to a target's Mac. By livestreaming the desktop or exfiltrating screenshots, this information can be used for blackmail and targeted social engineering attacks to further compromise the mark.
Web 2.0 technology has provided a convenient way to post videos online, keep up with old friends on social media, and even bank from the comfort of your web browser. But when applications are poorly designed or incorrectly configured, certain flaws can be exploited. One such flaw, known as CSRF, allows an attacker to use a legitimate user's session to execute unauthorized requests to the server.
In most macOS hacks, a non-root terminal is used to create a backdoor into the device. A lot of damage can be done as a low-privileged user, but it has its limitations. Think twice before granting a file permission to execute — an attacker might be able to convert your harmless scripts into persistent root backdoors.
One of the most critical bugs to come out in the last five years was Shellshock, a vulnerability which allows attackers to execute arbitrary code via the Unix Bash shell remotely. This vulnerability has been around for a while now, but due to the ubiquity of Unix machines connected to the web, Shellshock is still a very real threat, especially for unpatched systems.
