How To: Program a $6 NodeMCU to Detect Wi-Fi Jamming Attacks in the Arduino IDE

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.

Mac for Hackers: How to Set Up a MacOS System for Wi-Fi Packet Capturing

MacOS isn't known as an ideal operating system for hacking without customization, but it includes native tools that allow easy control of the Wi-Fi radio for packet sniffing. Changing channels, scanning for access points, and even capturing packets all can be done from the command line. We'll use aliasing to set some simple commands for easy native packet capture on a macOS system.

How To: Stream Games from Your Windows PC to Your iPhone

The greatest pain in owning a high-powered gaming PC is the simple fact that you can't play it all the time. Sometimes you have work or school, and other times, you may just want to go mobile. When something like this impedes your ability to play PC games, you may end up settling for mobile games. What if, instead of doing that, you were able to play your PC games from your iPhone?

News: 5 Major Problems Magic Leap One Faces on Day One

The mysterious technology product teased via an eccentric TED Talk nearly five years ago has finally been revealed, and it's called the Magic Leap One: Creator Edition. After all of the non-disclosure agreements, furtive comments from CEOs and insiders given early access to the device, and a seemingly never-ending string of hints dropped by the company's CEO, Rony Abovitz, on Twitter, we finally have a real look at the product.

How To: Log into Your Raspberry Pi Using a USB-to-TTL Serial Cable

Connecting to your headless Raspberry Pi on the go typically requires a network connection or carrying around bulky peripheral hardware like a screen and keyboard. With the help of an old-school connecting standard, though, you can log into your Pi from any computer using a simple cable. If you don't have a power source, you can also power your Linux distro over the cable at the same time.

How To: Change These Settings Now to Protect Your Data in Case Your Phone Is Stolen

As smartphone users, we live in dangerous times. The value of phones continues to rise, making them prime targets for thieves. In 2015, the FCC estimated that one million phones are stolen each year, and with several devices starting to hit the $1,000 mark now, these numbers are sure to rise. But what do you do if you fall victim to phone theft?

How To: 8 Ways to Increase Battery Life on Your LG V30

The LG V30 has solid battery life. With its QHD P-OLED screen and 4 GB RAM, it's able to maintain all-day performance with average use. Heavier users might find that its 3,300 mAh battery isn't quite enough for a full day of work, though, but with a few software tweaks, you can squeeze out even more battery life.

How To: The 5 Best Phones for Video Chat

Video chatting has become an important factor in the overall smartphone experience. Even just a few years ago, 37% of teens were making video calls on a regular basis, and that number has surely grown. 85% of households with infants have used video chat apps to call relatives in other cities, and it's been shown that toddlers can create bonds and learn from visual cues in video calls.

How To: Your One-Stop Guide to Secure, Encrypted Messaging

Now that smartphones have ensured that we're connected to the internet 24/7, online privacy has become more important than ever. With data-mining apps hoping to sell your information for targeted ads, and government agencies only one subpoena away from knowing every detail of your private life, encryption has become our last line of defense.

How To: Detect & Classify Wi-Fi Jamming Packets with the NodeMCU

The most common Wi-Fi jamming attacks leverage deauthentication and disassociation packets to attack networks. This allows a low-cost ESP8266-based device programmed in Arduino to detect and classify Wi-Fi denial-of-service attacks by lighting a different color LED for each type of packet. The pattern of these colors can also allow us to fingerprint the tool being used to attack the network.
