In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
Hello and welcome to my article. I have made this article for anyone who wants to become a hacker, and wants to know how to get started.
Telemarketers can be as terrifying as a villain from a horror film. Your phone rings with an unknown 800 number, and you immediately fill with a sense of dread. There's no way to get them to stop calling; you imagine the number appearing on your phone at all hours of the day and night, haunting you.
It may sound irrational, but I bet a lot of you actually avoid doing any work at work—but not on purpose. You might be simply struggling with motivation, or you might just be overdosing on the caffeine. Whatever the issue, getting focused takes lots of time and effort.
The launch of Android 4.1 Jelly Bean was also the launch of Google Now, a service that was supposed to one-up Siri, the resident personal assistant for iOS devices. Google Now offered enticing features, but its launch went unnoticed by a great many Android users.
If you've been to a convention of any sort before, you know that there are good and bad panels, and that their inherent goodness or badness often has little to do with the actual content being discussed. That's because giving a panel is a skill that not everyone has. However, it is a skill that everyone could have! In this article, I'll tell you how to give a good panel on practically any subject.

I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but when you're a kid, these can be important issues to you. So I slept with my glasses on every night, just in case. Photo from George Pal's The Time Machine.
Some websites require you to perform a verification task so they know you're human and not a bot. It helps websites curb spam, abuse, unauthorized access, and cyberattacks but also adds an obstacle for anyone trying to visit their content. If you find it more of a nuisance than a necessary evil, there's an easy way to reduce the number of human verification prompts you receive on your iPhone, iPad, and/or Mac.
Your iPhone's Mail app has a lot of fantastic productivity features, such as unsending emails, follow-up reminders, opening drafts from almost any view, the snooze option, bulk-selecting messages, and the formatting toolbar, but one of the most helpful ones might just be the one you're not using.
If you use Goals in Google Calendar, you've probably already received the notification that Google, in typical executioner fashion, has marked the feature for death. As of November 2022, you can't create new goals, and your current goals won't repeat anymore. Google suggests switching to repeating events or tasks, but there's a better option to use on your Android and iOS device.
If you're like me, you're not too keen on being tracked. So when an app asks you if it can track your iPhone activity across other programs and websites for ads or data brokers, the answer is pretty much always "no." If you're tired of choosing "Ask App Not to Track" over and over again, there is a way to stop apps from even being able to ask in the first place.
Users on Android could customize their app icons for some time, but it's a relatively new addition to the iPhone. You could change icons since iOS 12, but it really took off in iOS 14 and got even better in iOS 14.3. Still, it's not as easy as on Android, and you'll see a notification every time you open an app with your custom icon. However, there is a workaround to stop those annoying notifications.
Apple has an excellent reputation for its privacy and security policies. That said, it isn't a perfect reputation. Take Siri, for example. The helpful iOS assistant isn't just communicating with you — Apple saves and listens to a history of your Siri interactions. If you don't want Apple storing your Siri history forever, there's something you can do about it.
Aside from home screen widgets, one of the most exciting updates to the iPhone with iOS 14 is Picture in Picture mode. With it, you can watch minimized versions of videos on top of other apps so you can multitask like a pro. However, not every service is on board with Apple's new features. YouTube is the primary culprit, but there is a workaround.
Have you ever watched a video on your iPhone but wanted to look at something else real quick? Before iOS 14, you had to choose between pausing the video or waiting until it's over — not exactly ideal for a device that's supposed to help you multitask. But with iOS 14 or later, we can use picture-in-picture mode to watch and perform other on-screen tasks at the same time.
Apple's AirPods are convenient because you can easily switch which Apple device is connected to your AirPods with just a few taps. But unless you're using Shortcuts to make the connection, you aren't using the fastest method possible.
I've covered augmented reality apps for about three years now and the most useful mobile app I've encountered over that time is Google Lens.
The original iPhone SE was, for some, the perfect iPhone. It brought back the popular one-handed form factor of the iPhone 5 but packed in the internals of the then-new iPhone 6S. Now, the second-generation iPhone SE is here for 2020, but can it live up to what made the first-generation iPhone SE so popular?
While hackers know and love the Raspberry Pi, many don't know of its cheaper cousin, the microcontroller. Unlike a Pi, which can be used more or less like a regular computer, microcontrollers like the Wi-Fi connected ESP8266 require some necessary programming skill to master. In this guide, we'll build an Arduino program from scratch and explain the code structure in a way anyone can understand.
One of the best things about Android is the ability to customize every aspect of your device to make it your own. However, unless you have prior knowledge or experience with every single setting available to you, you might have missed a few critical features without even knowing it. Some settings are easy to find, while others might be tucked away in another menu of their own.
Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
Hackers often rely on lazy system admins and unpatched vulnerabilities to get access to a host. Keeping intruders off of our machines requires us to update daily, only run the services we need, and read the code, among other things, but we can still make mistakes. Luckily for us, we can limit the damage caused by those mistakes by running SELinux.
During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value. While that's all well and good, arbitrary values are boring. We want to gain full control over the values we write, and today we are going to learn how to do just that.
Coinbase is the primary go-to for many users when it comes to investing in Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Ripple (XRP), and more, due to its user-friendly interface. But before you join them, know that the ease of use comes with a price. Coinbase charges fees for each transaction, and your bank might even add charges on top of that. Plus, there is some fine print to be aware of.
It always looks different when it's not about you. The Internet is our world's Alterego. Those many bits don't really make sense unless we want them to be valuable, to mean something.
Welcome back Hackers\Newbies!
First of all, I would like you all to meet my good friend Iggy. There he is, in all his scaly reptilian glory. As you can see, he spends a lot more time on top of his cage than inside of it. You see, Iggy here doesn't deal well AT ALL with confinement. I don't know if it's possible for a lizard to be claustrophobic, but if it is possible, then Iggy definitely is. When his previous owner gave him to me, I tried to keep him in the cage, but I quickly realized that it was a bad idea. When confin...
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...
Android 12 comes with new features and upgrades that any mobile gamer can appreciate, including Instant Play, which lets you play games instantly without downloading them first. Even better, there's Game Dashboard, which adds shortcuts for screenshots, screen recordings, and more in whatever game you play. The only problems are that it's not enabled by default, and it's a little hard to find.
If your Safari browser is lagging when opening new tabs or windows on your Mac, there's an easy fix that will speed things back up to how they're supposed to be.
Among the various components of the emerging augmented reality space, the most lucrative is the advertising market. The prospect of turning every object, every location, ever signpost in the real world into a discount code or virtual transaction interface is why AR will ultimately be more profitable than VR.
You have an assignment due, whether it's homework for school or a project for work, but you've only got a few hours left. There's no way you're going to finish in time and do a good job, and you don't want to turn in anything incomplete or half-assed. While it may seem you're out of luck, there's a simple way to buy yourself more time.
3D printers allow hackers and makers alike to create something from nothing. They're an incredible technology that lets you build protective cases and covers for gear such as a wardriving phone and Raspberry Pi-Hole. 3D printers can even help you out in a bind when something breaks, and it's impossible to get the part, since you can just print one out yourself.
Phone specs get better and better each year, and multiplayer mobile games are right there with them. Instead of playing solo, jump into some real-time gameplay with co-op and player vs. player modes, and battle friends, family, and strangers from around the world. But which multiplayer games are worth your time on Android or iOS?
Well before Magisk was in our lives, the Xposed framework was where all the mods and magic happened. Magisk was built on a similar concept with the ability to customize your system via modules. We can thank Xposed for where we are today in terms of root-related mods, but it's not done just yet — it's still very much alive and kicking after all these years.
With the list of available mobile apps for moviegoers constantly expanding and improving, seeing a film at your local theater has never been better. With the right apps for your iPhone or Android phone, you can research movies, find out if showings are sold out, reserve seats, save money on tickets and concessions, preorder popcorn and soda, and even find dull bathroom-worthy scenes.
While our time with the Protostar VM from Exploit Exercises was lovely, we must move on to bigger things and harder challenges. Exploit Exercises' Fusion VM offers some more challenging binary exploitation levels for us to tackle. The biggest change is that these levels are all network services, which means we'll write our first remote exploits.
No more carrying around heavy laptops and thousands of Linux Live CDs and USBs to always be ready for pentesting on the fly!
Did you know Kali 1.0.8? You probably did, and you probably know about the EFI boot option that has been added.
Apple AirTags are super helpful for keeping track of your keys, backpack, and other frequently misplaced items, but there are some pretty clever things you can do with them beyond finding regularly used stuff.
