If you're going to build yourself a water gun to cool down this summer, or maybe just a useful water pump, you'll need some check valves. However, the most expensive parts of a water pump or DIY super soaker are usually the check valves. So, let's make some from scratch for as little as $0.35 each.
At one point in the '90s, about fifty percent of the CDs produced worldwide had an AOL logo. About fifty percent of the CDs in my home still have that AOL promise of 500 free hours on them. Though they never got me to join their internet service, I did get a lifetime supply of coasters. Thanks to the rise of high-speed internet access and bigger and better hard drives, there's no reason for companies to snail mail any more of those obnoxious plastic discs.
Last time, I showed how to start putting together an AC arc welder from scavenged microwave parts, focusing on the transformer modifications. Now, I'll show you how to finish up your DIY stick welding machine by fixing up the electrical system and performing the finishing touches.
Back in 2010, iOS developer Daniel Amitay developed a camera security app for iPhones that used an unlock screen almost identical to that of the iPhone.
People are always looking for ways to save money, and for the most part, saving money and cheating the system are synonymous when it comes to things like free internet access. Practically every new gadget is capable of connecting to the web, which means more and more people are looking for ways around those hefty internet bills.
If you bought an iPhone or iPad equipped with USB-C but didn't max out the local storage, there are some great external storage solutions beyond iCloud and other cloud storage services. And now that the iPhone lineup comes with USB-C ports, you have better-performing external drives available to you than anything you could ever get for a Lightning-based model.
Apple released the second beta for iOS 15 on Thursday, June 24. The update includes FaceTime's "SharePlay" feature for the first time, a new Maps icon, updates to Focus mode, in addition to many other changes and bug fixes.
Apple has four iPhone models for the remaining months of 2020, but the most impressive ones are the iPhone 12 Pro and iPhone 12 Pro Max. While the iPhone 12 and iPhone 12 mini are great smartphones, the "Pro" models offer more advanced features, especially for photographers and augmented reality enthusiasts.
Not all Kickstarters are created equal. Some take forever to get their products to supporters, and when the product does arrive (usually much later than promised) it's often very rough around the edges.
The Chicago Bulls may not be very relevant in the current NBA standings, but they do lead the league in one other area.
Bud Light being the official beer sponsor of the NFL just makes sense for American football. But what about the NHL, with hockey being the official winter sport of Canada by decree?
While iOS 14.3 is available to everyone right now, Apple is currently working on iOS 14.4 in its beta programs, and the second iOS 14.4 beta just came out for developers. The public beta version of iOS 14.4 beta 2 was released soon after. But what's in these new betas?
You won't have to ask Santa for holiday-themed augmented reality experiences, because practically any social and shopping app that offers AR effects has them available now.
No doubt, you've heard a lot about 5G lately. This might have you looking at your current 4G phone and lamenting your inability to connect to the faster network. But is 5G worth buying a new phone over, and should you buy one right now?
For a hacker, there are a lot of advantages to creating a fake network. One advantage forces nearby devices to use their real MAC address if you happen upon a network that's stored in their preferred network list.
If your new 2020 iPhone SE is frozen, unresponsive, or won't load the system, and a standard power down and up procedure didn't work, there are few more things you can try. Force-restarting the device may do the trick, recovery mode is a last-ditch option, and DFU mode is your fail-safe.
Anything from work or a missed flight to a worldwide pandemic (COVID-19, anyone?) can make it difficult or nearly impossible to see your loved ones. You can make phone calls or send iMessage, text, or email messages, but nothing compares to seeing family and friends right in front of you. That's where FaceTime comes in.
Arduino is a language that's easy to learn and supported on many incredibly low-cost devices, two of which are the $2 Digispark and a $3 ESP8266-based board. We can program these devices in Arduino to hijack the Wi-Fi data connection of any unlocked macOS computer in seconds, and we can even have it send data from the target device to our low-cost evil access point.
For anyone interested in using cheap, Wi-Fi-connected microcontrollers like the ESP8266, the Arduino programming language can be a barrier to entry. Based on C++, Arduino requires knowledge of more computer science than languages like Python. Fortunately for beginners, setting up MicroPython on an ESP8266 allows anyone to write Python on affordable microcontrollers in a matter of minutes.
Pyrit is one of the most powerful WPA/WPA2 cracking tools in a hacker's arsenal, with the ability to benchmark a computer's CPU speeds, analyze capture files for crackable handshakes, and even tap into GPU password-cracking power. To demonstrate how quickly it can hack a WPA/WPA2 password, we'll use it to play a Wi-Fi hacking CTF game anyone can practice for less than $10.
The USB Rubber Ducky is a famous attack tool that looks like a USB flash drive but acts like a keyboard when plugged into any unlocked device. The Ducky Script language used to control it is simple and powerful, and it works with Arduino and can run on boards like the ultra-cheap Digispark board.
When Apple acquired the popular Workflow app in 2017, many were worried that it would either get replaced with something much worse, or just disappear entirely. Thankfully, Apple put these concerns to rest with the launch of Shortcuts. In iOS 13, Shortcuts is becoming more powerful than ever, providing functionality on the iPhone that the original Workflow team could only dream of.
While MacOS computers have been spared from some of the most famous malware attacks, there is no shortage of malicious programs written for them. To keep your computer safe from some of the most common types of malware, we'll check out two free tools. These tools can automatically detect ransomware encrypting your files and watch for unauthorized access to your microphone and camera.
Starting Sept. 13, you can preorder the iPhone 11, 11 Pro, or 11 Pro Max from Apple, wireless carriers, and various e-commerce websites. However, unlike with Android smartphones, there is only one set of iOS phones that come out each year, so they're pretty hot items. That means being the first to get your hands on one could be a challenge, but we're here to help you out.
QR codes are everywhere, from product packaging to airline boarding passes, making the scanners that read them a juicy target for hackers. Thanks to flaws in many of these proprietary scanning devices, it's possible to exploit common vulnerabilities using exploits packed into custom QR codes.
You may have recently seen a plethora of Instagram users, including celebrities and politicians, sharing a screenshot declaring that the platform will implement a new "rule" where it would own and could use your photos and videos however it wishes. The screenshots are part of an internet hoax, one that's been around in one way or another since 2012, but what can Instagram actually do with your media?
Search engines index websites on the web so you can find them more efficiently, and the same is true for internet-connected devices. Shodan indexes devices like webcams, printers, and even industrial controls into one easy-to-search database, giving hackers access to vulnerable devices online across the globe. And you can search its database via its website or command-line library.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
If you're worried about the security of your Mac, there are easy measures to prevent the most dangerous attacks. Named after the tactic of accessing an unattended computer in a hotel room, we can thwart "evil maid" attacks with Do Not Disturb and LuLu, free macOS tools by Objective-See that keep an eye on unattended computers and flag suspicious network connections that indicate a malware infection.
Music streaming services make it difficult to transfer your favorite songs and artists from one service to another and for a valid reason: they don't want you to leave. But when it comes to switching, playlists are a big concern, because who wants to do it all over again? Luckily, if you're moving from Spotify to Apple Music, you can use a third-party app to take playlists with you.
You're in constant communication with your friends and family. The only issue? Nobody uses the same app. Messenger, Instagram, WhatsApp — you have contacts spanning all three, and the resulting balancing-act to keep in touch can be overwhelming. That's why Facebook — who owns all three apps — is coming out with a way to call and message friends across all three platforms from one place.
EternalBlue was a devastating exploit that targeted Microsoft's implementation of the SMB protocol. Metasploit contains a useful module that will automatically exploit a target, as long as it's vulnerable. But what if we wanted to exploit this vulnerability without Metasploit holding our hand? It can be done using a Python file to exploit EternalBlue manually.
Many of our online accounts now come with an added two-factor authentication (2FA) functionality to help keep our data safe. This essentially means no one would be able to access the account until a specific set of requirements were met. It could be a combination of a password with a security key or even a passcode with some form of biometrics, like a fingerprint or face scan.
Back in 2015, Amazon Prime Video was the first subscription-based streaming service to introduce the ability to download movies and TV shows for offline viewing on mobile devices. For travelers and users with limited data plans that like to watch films and episodes on the go, this was a godsend. Amazon has updated its apps many times since then, but the process remains relatively the same.
With just a few taps, an Android phone can be weaponized into a covert hacking device capable of running tools such as Nmap, Nikto, and Netcat — all without rooting the device.
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.
For anyone wanting to keep information private, plain text is a format of the past. Instead, cheap, powerful encryption is widely available, but often not easy enough to use to attract widespread adoption. An exception to this rule is EncryptPad, an easy to use application that lets you encrypt text, photos, or archives with strong encryption using a password, keyfile, or both.
The Raspberry Pi Zero W and Pi 3 Model B+ include integrated Wi-Fi, Bluetooth Low Energy, and more than enough power to run Kali Linux. They sound like perfect all-in-one penetration testing devices, but the lack of support for monitor mode and packet injection usually meant buying a supported Wi-Fi adapter. Now, it's possible to use monitor mode on the built-in Wi-Fi chip with Nexmon.
Everyone from first responders to hotel cleaning staff use radios operating in the sub-megahertz range to communicate, often without even encoding the transmission. While encoding and encryption are increasingly used in radio communication, an RTL-SDR adapter and smartphone are all it takes to start listening in on radio conversations happening around you.
Apple's new iPhone XR, XS, and XS Max are sure to be hits this year. Of course, that means plenty of hungry customers are looking to sign up for a model once preorders begin on Friday, Sept. 14, for the XS models, and Oct. 19 for the XR. Luckily, there are preemptive actions you can take right now to avoid waiting outside an Apple Store overnight or getting kicked out of the preorder queue online.
