I am an English major physically allergic to all algebraic formulas, so you're unlikely to get any help from me when it comes to solving any expressions. But in the glorious technological age we live in, there are plenty of apps that actually make math and problem solving fun, even a little bit addictive.
I love cryptography. It is like a great gigantic puzzle for me to solve. However, it is more important than that. It is also how we keep secrets safe. Not just sorta safe either, but really safe.
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
The Digispark is a low-cost USB development board that's programmable in Arduino and capable of posing as a keyboard, allowing it to deliver a number of payloads. For only a few dollars, we can use the Digispark to deliver a payload to a macOS computer that will track the Mac every 60 seconds, even bypassing security like a VPN.
There are times when physically interacting with your iPhone is less than ideal, like when you're cooking or driving. Fortunately, iOS 13 has you covered regardless of the circumstance you may find yourself in. With the new Voice Control feature, you can control pretty much everything on your device without even touching it.
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.
Open-source intelligence researchers and hackers alike love social media for reconnaissance. Websites like Twitter offer vast, searchable databases updated in real time by millions of users, but it can be incredibly time-consuming to sift through manually. Thankfully, tools like Twint can crawl through years of Twitter data to dig up any information with a single terminal command.
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.
You may not know it, but the IPv4 address of your computer contains tons of useful information about whatever Wi-Fi network you're on. By knowing what your IPv4 address and subnet mask are telling you, you can easily scan the whole network range, locate the router, and discover other devices on the same network.
It only takes a few commands to manipulate a MacBook's secure HTTPS traffic and pluck login passwords out of the encrypted data. Let's take Facebook and Gmail hacking to the next level by intercepting Safari and Google Chrome web traffic in real time.
It's easy to have your password stolen. Important people like executives, government workers, journalists, and activists face sophisticated phishing attacks to compromise their online accounts, often targeting Google account credentials. To reduce this risk, Google created the Advanced Protection Program, which uses U2F security keys to control account access and make stolen passwords worthless.
Surveying a target's Wi-Fi infrastructure is the first step to understanding the wireless attack surface you have to work with.
Greetings all. Today I intend to append a new series to my mini-collection of posts. This series will consist of informative guides for the purpose of depicting certain aspects of the White Hat profession that I believe are of profound importance. Furthermore, I will keep this series simple for everyone to follow, regardless of your tech level. So without further ado, let's get right into it.
Android comprises an entire ecosystem of apps, games, functions, and features, so it would only make sense that it has its own lexicon. Words, phrases, and acronyms that didn't exist ten years ago are now used in an off-the-cuff style by developers and support technicians across the web.
Running out of storage space on your iPhone is annoying, but trying to free some up is downright aggravating. Until they figure out a way to throw a terabyte of flash memory in there, you're going to have to do some spring cleaning every now and then, especially if you're trying to update to iOS 8.
If you're in the market for a new smartphone, there are some pretty fantastic options for $400 or less. Both Apple and Google have unveiled budget smartphones with high-end specs in 2020, so you no longer have to suffer from subpar quality to save a few bucks. Low prices no longer mean cheap phones.
Android phones finally have a true AirDrop alternative called "Nearby Share." The new feature was added through an update to the Google Play Services app that comes pre-installed on all Android devices in the US, so you don't even have to wait on a firmware upgrade — it's just there.
Smartphones are inherently bad for privacy. You've basically got a tracking device in your pocket, pinging off cell towers and locking onto GPS satellites. All the while, tracking cookies, advertising IDs, and usage stats follow you around the internet.
It's always a big deal when the company that makes Android releases a new phone. Google's Pixel series has made a name for itself in three short years behind its camera prowess, but now it's time to start competing with the major players. That said, Google should like how their Pixel 4 and 4 XL stack up against the iPhones and Galaxies of the world.
A hacker with privileged access to a Windows 10 computer can configure it to act as a web proxy, which allows the attacker to target devices and services on the network through the compromised computer. The probes and attacks appear to originate from the Windows 10 computer, making it difficult to detect the attacker's actual location.
A lot of people still trust their web browsers to remember every online account password for them. If you're one of those users, you need to adopt a more secure way of managing passwords, because browser-stored passwords are hacker gold mines. With a USB Rubber Ducky and physical access to your computer, they can have a screenshot of all your credentials in their inbox in less than 60 seconds.
You don't have to be a frequent flyer to know how indispensable navigation apps have become. Many of us rely on these apps for traveling from state to state and getting around in foreign cities, but even more of us count on these apps to beat rush hour traffic and find the quickest routes to school or work. So naturally, we all have our favorite mapping apps, but which one is truly the best?
The OnePlus 7 Pro is definitely a beast on paper. With a specs page that ticks virtually every box and a price point that undercuts the competition by hundreds of dollars, it's hard to overlook this phone. But before you get too excited, know that OnePlus has repeatedly shown to be misleading with their official specs.
On the surface, AppleCare+ seems like an expensive and gimmicky option to tack onto your already pricey iPhone 11, 11 Pro, or 11 Pro Max. Upon further inspection, however, you'll see that its seemingly expensive price tag is chump change compared to the fees you'll have to pay if you end up having to repair your premium device outside its one-year warranty.
The calendar app is one of the unsung heroes found within your iPhone. It's the ultimate personal assistant that you've come to rely on to keep track of your schedule and ensure you never miss a class or meeting, all while reminding you of upcoming birthdays and deadlines to help maintain good relationships with loved ones and colleagues.
Smartphones are still "phones," which means communicating with others is usually a primary use. Ranging from a simple "hi" to a more personal conversation and even sharing passwords, our messages should remain private so that only the intended recipient sees their content. While many apps tout end-to-end encryption, not all apps prioritize security and privacy.
Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time.
Autism affects 1 in 68 children in the US, and that means it affects at least 1 in every 68 families. More boys than girls are diagnosed as being on the autism spectrum, and it's estimated that almost 60,000 12-year-olds in the US have autism. That is a 37-fold increase from the 1 in 2,500 children diagnosed just 30 years ago.
For all of its many perks — from the best iPhone camera system money can buy, to arguably the best smartphone display on the market — the iPhone 12 Pro Max is undeniably huge. It has the largest iPhone screen to date despite being 0.46 cubic inches smaller than the iPhone 11 Pro Max in overall size. If you're finding it a little too much to handle with one hand, there are ways to make it much easier to use.
Over the past decade, Marvel Studios has been a dominant force at the box office, raking in more than $21 billion dollars. Averaged out over that span of time, the yearly earnings of those movies outweigh the gross domestic product of some countries.
Windows 10 and macOS have poor reputations when it comes to customer privacy and user policies. Our hacking Windows 10 and hacking macOS articles might make it seem like a reasonably secure operating system doesn't exist. But I'm here to tell you that there is a viable alternative that could provide some sense of security and trust.
Privacy and security go hand in hand, especially for smartphones. When it comes to privacy, you decide what personal information about yourself is out there to discover. Security, on the other hand, is all about enforcing those privacy decisions.
No more carrying around heavy laptops and thousands of Linux Live CDs and USBs to always be ready for pentesting on the fly!
Your iPhone is fairly secure by default, but Apple's Lockdown Mode takes it to Fort Knox levels of protection. If you're a high-value target for spyware, phishing attempts, and other sophisticated cyberattacks, it's an essential feature. But for almost everyone else, it's an extreme move. If you simply want to verify someone's identity when chatting, Contact Key Verification is a more practical option.
In less than a month, WWDC, Apple's Worldwide Developers Conference, will reveal the company's plans for the upcoming iOS 18 and iPadOS 18 software updates. But we already know what accessibility features will be hitting iPhones and iPads later this year, and many of them will be helpful to everyone, not just users with accessibility issues.
If you can't curb your TikTok obsession, at least make it more efficient by taking your hands out of the equation. So when you're eating breakfast, working on your computer, or using your hands for another non-TikTok task, you don't even have to touch your iPhone or iPad to scroll through all of those videos in your feed. Instead, you can just tell it what to do, and it'll listen.
There are hidden Wi-Fi networks all around you — networks that will never show up in the list of available unlocked and password-protected hotspots that your phone or computer can see — but are they more secure than regular networks that broadcast their name to any nearby device?
Although the Clock app in iOS has undergone some design changes over the years, you still can't set more than one timer on your iPhone. Oddly enough, Apple's own HomePod speaker added this feature, mimicking the timer on Amazon's popular Echo smart speakers. Fortunately, through Apple's Shortcuts app, there's a clever hack to set multiple timers — without using a third-party timer app.
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.
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.
