Where Do I Start: Learn the Fundamentals

I am very new to Null Byte but I find much of its content and community incredibly interesting. I spent quite a bit of time just chronologically going through the posts and I noticed a common theme in many of the beginner posts. Many people seem to want to know the 'secret' or a paragraph on "How to Hack" and become a hacker in a few minutes. I started off this post as a reply to a question from a beginner but thought it might be beneficial to have for those stumbling across this site.

Hack Like a Pro: Digital Forensics for the Aspiring Hacker, Part 7 (Windows Sysinternals)

Welcome back, my aspiring hackers! In many of my earlier tutorials, I mentioned the complementary nature of hacking and forensics. Both disciplines, hacking and forensics, benefit from a knowledge of the other. In many cases, both disciplines will use the same tool. In this tutorial, we will use another tool that can be used in either discipline—Sysinternals—a suite of tools developed by Mark Russinovich.

Hack Like a Pro: How to Hack Facebook (Same-Origin Policy)

Welcome back, my budding hackers! This is the initial post of a new series on how to hack Facebook. It's important to note here that each hack I'll be covering is very specific. I have said it before, but I feel I need to repeat it again: there is NO SILVER BULLET that works under all circumstances. Obviously, the good folks at Facebook have taken precautions to make certain that their app is not hacked, but if we are creative, persistent, and ingenious, we can still get in.

How To: Unjailbreak Your iPhone & Restore It Back to Factory Settings

Jailbreaking gives you root access to the iOS file system, allowing you to install third-party apps and tweaks on your iPhone that aren't available in the App Store. It opens up a whole new realm for what your device can do, but it can also cause instability across the system and can dissuade you from getting future updates from Apple that have important features, bug fixes, and security enhancements.

How To: Understanding Signature Schemes: How Data Sources Are Authenticated, Secured, & Spoofed

One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams.

How To: Avoid Insane Airline Baggage Fees by Packing Your Luggage Like a Pro Traveler

The airline is not your friend. It will do anything it can to gouge your dignity, time, and most of all, money. One of the biggest scams to get a few extra bucks out of you are those dreaded baggage fees. If the lines, security, "random" screenings, and unwanted fondling aren't bad enough, you have to pay them to check your bags (which, most of the time, is done poorly). Flying truly is the most inconvenient way to travel.

How To: Use iOS 15's Built-in Authenticator as a Secure 2FA Method for All Your Accounts

Most websites and apps support two-factor authentication (2FA), which adds an extra layer of security to your accounts by requesting another form of identification beyond username and password. The second factor can be a recovery code, physical security key, or one-time password (OTP) that only you can access, even if someone else has your password. This process is easier than ever thanks to iOS 15.
