How to Hack Wi-Fi: Cracking WPA2 Passwords Using the New PMKID Hashcat Attack

Cracking the password for WPA2 networks has been roughly the same for many years, but a newer attack requires less interaction and info than previous techniques and has the added advantage of being able to target access points with no one connected. The latest attack against the PMKID uses Hashcat to crack WPA passwords and allows hackers to find networks with weak passwords more easily.

How To: Calibrate the Colors of Your Pixel 2's Display with ElementalX

No matter how good a display is, the idea of perfect color calibration is subjective — some prefer warmer more saturated colors, while others prefer the calmer cooler side of the color spectrum. It is almost impossible to create a single color calibration that everyone can agree on out of the box. The display on the Pixel 2 XL was specifically calibrated with a more realistic color profile in mind.

But a leaked version of the beta has already hit the internet.

How to Hack Wi-Fi: Disabling Security Cameras on Any Wireless Network with Aireplay-Ng

Electronic warfare tactics work by jamming, disrupting, or disabling the technology a target uses to perform a critical function, and IoT devices are especially vulnerable to attacks. Wireless security cameras like the Nest Cam are frequently used to secure critical locations, but a hacker can surgically disable a webcam or other Wi-Fi connected device without disturbing the rest of the network.

How To: Unroot & Revert Your OnePlus 5 or 5T to 100% Stock

To please those of us who love to mod and root our Androids, OnePlus has made both the OnePlus 5 and 5T relatively easy to customize — so much so that the 5T topped our list for the best phones for rooting. Unfortunately, unlocking the bootloader and using root to modify the firmware on your OnePlus 5 or 5T makes it hard to update to a new firmware such as Oreo when compared to stock.

How To: Use the Chrome Browser Secure Shell App to SSH into Remote Devices

Many guides on Null Byte require using the Secure Shell (SSH) to connect to a remote server. Unfortunately for beginners, learning to use SSH can become a confusing mix of third-party programs and native OS support. For Chrome OS users, using SSH is even more difficult. We'll fix this by using the Chrome Secure Shell to establish an SSH connection from any device that can run a Chrome browser.

Compared: The Best Antivirus & Security Suite Apps for Android

The Play Store hasn't been the most secure place for apps lately. A quick Google search for "Play Store malware" will give you a taste of some of the malicious apps that snuck their way onto Android's official app store. Google is aware of the problem and they're tying to fix it, but their new Play Protect program doesn't have a great track record, so you might want to look elsewhere.

How To: Create a Native SSH Server on Your Windows 10 System

With the addition of the OpenSSH client and server in the Windows 10 Fall Creators Update, you no longer have to rely on third-party programs to open an SSH server and connect to a Windows machine. While still a beta feature, this represents a long-overdue update fulfilling a promise made back in 2015.

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.

Hacking Pranks: How to Flip Photos, Change Images & Inject Messages into Friends' Browsers on Your Wi-Fi Network

Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing us to intercept and modify network data. This can be dangerous for private data, but also be fun for pranking your friends.

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: Exploit DDE in Microsoft Office & Defend Against DDE-Based Attacks

In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.

How To: Generate Private Encryption Keys with the Diffie-Hellman Key Exchange

When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.

How To: Your Phone's Biggest Security Weakness Is Its Data Connection — Here's How to Lock It Down

After numerous scandals like the Equifax data breach and the 2016 US election, cybersecurity has become a significant issue for Americans. Unfortunately, anytime we use our devices, we're open to a cyber attack — especially when we browse the web. However, there are ways that we can make it harder for hackers and data miners.

How To: Use Private Encrypted Messaging Over Tor

Tor is an excellent obfuscation network for web traffic, and while instant messaging over the network is very useful, it can be relatively difficult to configure. In this guide, we'll look at two synchronous communications platforms (instant messengers) which can be routed over the Tor network, Ricochet and XMPP.

How To: Hack Forum Accounts with Password-Stealing Pictures

The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data. Profile pictures, avatars, and image galleries are used all over the internet. While all images carry digital picture data — and many also carry metadata regarding camera or photo edits — it's far less expected that an image might actually be hiding malicious code.

How To: Install Magisk on Your Pixel or Pixel XL

Google's Pixel phones claimed the top spot in our ranking of the best phones for rooting, but they do have one drawback from a modder's perspective: Because of their A/B partition layout for seamless updates, the devices don't have official support for Magisk. Thankfully, though, developer goodwin has stepped in with a fix, so we can now get Magisk working on the Pixel and Pixel XL.

How to Hack Wi-Fi: Capturing WPA Passwords by Targeting Users with a Fluxion Attack

With tools such as Reaver becoming less viable options for pen-testers as ISPs replace vulnerable routers, there become fewer certainties about which tools will work against a particular target. If you don't have time to crack the WPA password or it's unusually strong, it can be hard to figure out your next step. Luckily, nearly all systems have one common vulnerability you can count on — users!

How To: 10 Things Google Assistant Can Do to Make Your Life Easier

By combining years of web search advancements, natural language processing, and even DeepMind's artificial intelligence, Google Assistant hopes to change the way you interact with your devices. If you're familiar with Google's previous services, Google Assistant is like Google Now, Voice Search, and Now on Tap rolled into one service, with an extra layer of personality added on top. The end result is one central location for all of your Google needs, be it web search, screen search, playing m...
