How To: Inflate Any Ball Without a Pump or Needle

What happens when you find your ball deflated and there's no pump or needle in sight? You could always cancel your plans of kicking around the soccer ball or starting that pickup football game in the park. Better yet, you could be terribly clever and find another way to get air into the ball. From a pen to a balloon to a gas station, there are ways to inflate it.

How To: A Hitchhiker's Guide to the Internet: Today and Now, How It All Connects

In the first part of this series, we took a factual and technical look at the history of the Internet. I explained how all of these wires and servers got here in the first place. Obviously, a firm did not just create and build the Internet around 1995! Now that we know how the Internet came to be, we can get into the really fun stuff—what the Internet looks like now! Well, that's not quite the network design I was talking about, but it does show what the Internet looked like back in 2007 befo...

Spice Rack Explosives: How to Make Gunpowder with Salt & Sugar

The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder! Being able to make homemade gunpowder without a trip to the store can be a lifesaver, no matter if it's just for testing out a Civil War-era musket, blowing up stubborn tree stumps, or preparing for battle when imperialists overrun your country.

How To: Use Mitaka to Perform In-Browser OSINT to Identify Malware, Sketchy Sites, Shady Emails & More

Web browser extensions are one of the simplest ways to get starting using open-source intelligence tools because they're cross-platform. So anyone using Chrome on Linux, macOS, and Windows can use them all the same. The same goes for Firefox. One desktop browser add-on, in particular, makes OSINT as easy as right-clicking to search for hashes, email addresses, and URLs.

How To: Remove Unnecessary Profiles & Certificates on Your iPhone to Protect Your Privacy & Security

When you want to install a new tool or game on your iPhone, you go straight to the App Store to do so — but it's not the only place you can get apps from. Some developers use back alleys to get their apps to you, while others can trick you into installing them without giving it much thought. This can lead to malicious software running on your iPhone, software you'll want to get rid of asap.

How To: Hack SAML Single Sign-on with Burp Suite

Single sign-on (SSO) lets users login across different sites without having to manage multiple accounts. I'm sure most of us appreciate the convenience of seeing "Sign in with …" buttons that let us login with a single username. Hackers, however, see a possible avenue for exploitation, and you'll soon learn how an attacker can exploit a SAML vulnerability to assume another user's identity.

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.

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: Hide DDE-Based Attacks in MS Word

In a previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when a Microsoft Word document is opened. The biggest challenge of this attack is that it requires getting the user to agree to a pop-up prompt. Fortunately, since I posted that article, many new obfuscation techniques have been discovered to make this easier. Today, we explore and combine some of them to make the ultimate hidden DDE attack.

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.

News: 11 iPhone AR Demos That Will Change How We Use Our Phones

Apple demonstrated their continued interest and investment into the awesome world of augmented reality during their Sept. 12 event, highlighting a few new AR games that will appear on iPhones thanks to ARKit. But that's not all you can expect — as long as you have an iPhone with an A9 chip or later, there will be a ton of cool new AR tools, games, and other apps to play around from the App Store.

News: 10 Terrifying Diseases You're Going to Be Hearing a Lot More About

You may not have heard of visceral leishmaniasis, onchocerciasis, or lymphatic filariasis, and there is a reason for that. These diseases, part of a group of infections called neglected tropical diseases (NTDs), impact more than a billion people on the planet in countries other than ours. Despite the consolation that these often grotesque illnesses are "out of sight, out of mind," some of these infections are quietly taking their toll in some southern communities of the US.

How To: Become a Hacker

Many of our members here at Null Byte are aspiring hackers looking to gain skills and credentials to enter the most-valued profession of the 21st century. Hackers are being hired by IT security firms, antivirus developers, national military and espionage organizations, private detectives, and many other organizations.

Hack Like a Pro: How to Build Your Own Exploits, Part 3 (Fuzzing with Spike to Find Overflows)

Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see whether we can make it crash or overflow. This process is known as fuzzing. It is often the first step to developing an exploit, as we need to find some variable that is susceptible to overflowing.

How To: What You Need to Know Before Voting on Facebook's Proposed Policy Changes This Week

A few weeks ago, Facebook published a blog post called "Proposed Updates to our Governing Documents," which outlines a few changes in their policies and user voting system. These changes would essentially take away users' right to vote on future changes to Facebook's data use policy while also taking away Facebook's responsibility to alert users of those changes. If the new policy is enacted, the vote will be replaced with "a system that leads to more meaningful feedback and engagement," what...

How To: Research Your Family Tree Online

Are you interested in beginning research of your family's history? I began this journey about 3 or 4 years ago and here is what I found. I've done almost ALL of my research online, and gotten farther, faster and more comprehensively than anyone else who has researched my family the old fashioned ways. This is the kind of thing that technology is made for. Here's how to use it.

How To: When You Can't Sleep, Eat This

Being able to sleep deeply and fully is one of the foundations for real health. When you go without it, you feel subhuman and incapable of dealing with the world—just ask a student who's had to pull an all-nighter or the parents of a newborn. In fact, many studies have shown that lack of sleep or irregular sleep is linked to acne, weight gain, and depression.

How To: Use Your iPhone's Mail App to Send and Receive End-to-End Encrypted Emails in Gmail

Gmail uses TLS, or Transport Layer Security, by default for all email communications, so all of your emails will use the standard encryption as long as the recipients also support TLS. But there's a way to add even more security to your Gmail emails, and you can use your iPhone's Mail app to do it.

How To: 3 Reasons Why You Need iOS 14.5's New Privacy Features on Your iPhone

Many of us choose to use an iPhone — as well as other devices in the Apple ecosystem — because of the company's dedication to user privacy and security. If you need more proof of that commitment, look no further than iOS 14.5, released April 26, which adds new tools to protect our data while browsing the web and more control over the data installed apps collect on us.

News: 27 Best Productivity Apps to Make Working from Home Less Stressful

In the last decade, the number of people working remotely in the US has increased dramatically, and so has their need for technology and software to supplement that remote work. Whether you work from home or a coworking office space, the requirement for highly compatible and helpful productivity apps is a must if you want to get things done successfully.

News: 22 New Features in iOS 13.1 for iPhone You Won't Want to Miss

Apple released iOS 13.0 on Sept. 19 and announced on the same day the release of iOS 13.1 on Sept. 30. But that deadline was pushed up to Sept. 24, and that's why we have 13.1 just five days after 13.0. But that's good news since we don't have to wait any longer for some of the features promised in iOS 13 that didn't make the first cut.

How To: Get the Most Value from Your iPhone Trade-In

Phones these days are expensive. The iPhone 11 Pro is presumed to start at $999, following the iPhone XS and iPhone X's leads. One way to bring down that cost is to trade in your old iPhone, but there isn't one clear-cut way to do that. You could trade your iPhone into a participating website or put yourself out there and sell the iPhone on your own. It's all about what's best for you.
