How To: Install Gitrob on Kali Linux to Mine GitHub for Credentials

GitHub is an extremely popular site that allows developers to store source code and interact with other users about their projects. Anyone can download public, open-source files on GitHub manually or with Git, and anyone can fork off someone's project to expand or improve it into its own project. It's a really great site for programmers, developers, and even inspiring hackers.

How To: An Intro to Vim, the Unix Text Editor Every Hacker Should Be Familiar With

As pentesters and hackers, we're going to be working with text frequently — wordlists, configuration files, etc. A lot of this we'll be doing on our machine, where we have access to whatever editor we prefer. The rest of it will be on remote machines, where the tools for editing will be limited. If nano is installed, we have an easy-to-use terminal text editor, but it isn't very powerful.

Mac for Hackers: How to Install the Metasploit Framework

Metasploit is an extremely popular pentesting tool capable of enumeration, exploitation, and injecting shell code, and is a part of almost every hacking toolkit. So there's no way I could leave this out of our series on getting your Mac set up for hacking.

Mac for Hackers: How to Set Up Homebrew to Install & Update Open-Source Tools

After enabling disk encryption, creating encrypted disk images, installing KeePassX and iTerm2, and using Git with local repositories, the next step to getting your Mac computer ready for hacking is setting up a package manager that can install and update open-source hacking tools. There are multiple options to choose from, but Homebrew has a slight advantage.

Mac for Hackers: How to Use Git to Clone, Compile & Refine Open-Source Hacking Tools

With some of the groundwork out of the way in getting a Mac set up for hacking, it's time to start looking at toolboxes. Our first toolbox is Git, which will be used throughout future tutorials.

How To: Use UFONet

With the release of the Mirai source code, botnets are back in a big way. In the early days of botnets, zombies (infected hosts) would report to IRC (Internet Relay Chat) channels for CNC (command and control) instructions. Modern botnets have evolved, but they continue to use the same concepts as their predecessors.

Mac for Hackers: How to Create an Encrypted Disk Image

Before we dive any further into getting your Mac ready for hacking, I wanted to continue on with the concept of encryption. In the last part, we talked about full disk encryption on your Mac, but now I want to quickly cover the encryption of disk images before we dive into managing passwords, terminal emulators, etc.

How To: Use a Misconfigured SUID Bit to Escalate Privileges & Get Root

Gaining access to a system is always exciting, but where do you go from there? Root or bust. Sure, a compromised host is a great way to run a botnet, or do some other boring, nefarious thing—but as hackers, we want root. We also want to take the easiest path possible, search out low-hanging fruit, and exploit them. SUID programs are the lowest of the low-hanging fruit.

How To: Diceware Gives You Truly Random Yet Easy-to-Memorize Passwords

Passwords are everywhere. We use them to unlock phones, computers, websites, encrypted disks, encrypted files... the list just goes on and on. Savvy users will already have a password manager of some sort that can generate a very strong password on a per site basis. However, these password managers also require a password. Not only that, it has to be something memorable.

Mac for Hackers: How to Enable Full Disk Encryption to Protect Your Data

This is the very first article in my series on setting up a Mac for hacking. In this series, I will be operating under the assumption that you have a clean install of macOS (previously OS X). If you aren't starting with a clean installation, there may be a few differences, but nothing we can't help you out with.

Mac for Hackers: How to Get Your Mac Ready for Hacking

When it comes to hacking guides, most are written from the perspective of a Linux user. There are a few outliers, but it's mainly Linux, which leads to the idea that Linux is the only OS that's viable for hacking. This couldn't be further from the truth. A properly set up Apple machine can do quite a bit of heavy lifting.

How To: Disable WPAD on Your PC So Your HTTPS Traffic Won't Be Vulnerable to the Latest SSL Attack

You may not know what HTTP is exactly, but you definitely know that every single website you visit starts with it. Without the Hypertext Transfer Protocol, there'd be no easy way to view all the text, media, and data that you're able to see online. However, all communication between your browser and a website are unencrypted, which means it can be eavesdropped on.

How To: Brute-Force WPA/WPA2 via GPU

Most of you lot would be aware what WPA/WPA2 is so I won't bang on about the encryption or protocols a great deal. In short WPA and WPA2 both have a maximum of 256bit encrypted with a maximum of 64 characters in the password. The encryption is really only 64bit but x 4 because of the way the authentication functions as a 4 way handshake.

Hack Like a Pro: How to Get Facebook Credentials Without Hacking Facebook
