How To: Use SELinux Targeted Policy to Secure Your Hosts

Hackers often rely on lazy system admins and unpatched vulnerabilities to get access to a host. Keeping intruders off of our machines requires us to update daily, only run the services we need, and read the code, among other things, but we can still make mistakes. Luckily for us, we can limit the damage caused by those mistakes by running SELinux.

Hack Like a Pro: Python Scripting for the Aspiring Hacker, Part 2

Welcome back, my fledgling hackers! In an earlier tutorial, I introduced you to probably the most popular scripting language for hackers, Python. To become a professional hacker, you need to have some scripting skills and Python is a good choice if you want to master just one. In this latest guide, I will expand your background in Python and offer you a tidbit of Python code to whet your appetite for all of the hacking to come.

Exploit Development: How to Read & Write to a Program's Memory Using a Format String Vulnerability

Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.

Hacking macOS: How to Perform Situational Awareness Attacks, Part 1 (Using System Profiler & ARP)

The first few minutes after gaining access to a MacBook are critical — but where do we begin? Using tools built into macOS, we can develop an in-depth understanding of running background processes, detect antivirus software, locate sensitive files, and fingerprint other devices on the network. All of this can be done without installing additional software or modifying any files.

How To: Use Pupy, a Linux Remote Access Tool

In one of my previous articles, I discussed ShinoBot, a remote administration tool that makes itself obvious. The goal is to see if the user could detect a remote administration tool or RAT on their system. In this article, I'll be demonstrating the use of Pupy, an actual RAT, on a target Ubuntu 16.04 server.

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 Train Your Python: Part 3, Basic String Manipulation

Last time in how to train you python, we covered the basics of variables and output. While we were covering variables, we talked briefly about strings. "String" is just a fancier way of saying "Word". A string is simply a set of characters encased in quotations, this lets python know that it is a word. Sometimes when we do things with strings we'll need to change them in order to do something. Python is case sensitive, for example "Null-Byte" is not the same as "null-byte". This is where mani...

How To: Write Your Own Bash Script to Automate Recon

Automation has been a buzz word for quite some time now, but the principles behind it are as strong as ever. For a hacker or pentester, Bash scripting is one form of automation that cannot be ignored. Virtually any command that can be run from the terminal can be scripted — and should be, in many cases — to save valuable time and effort. And a Bash script just happens to be great for recon.

How to Hack Wi-Fi: Automating Wi-Fi Hacking with Besside-ng

Besside-ng is the hidden gem of the Aircrack-ng suite of Wi-Fi hacking tools. When run with a wireless network adapter capable of packet injection, Besside-ng can harvest WPA handshakes from any network with an active user — and crack WEP passwords outright. Unlike many tools, it requires no special dependencies and can be run via SSH, making it easy to deploy remotely.

How To: Writing 64-Bit Shellcode - Part 1 (Beginner Assembly)

In this simple tutorial you will be shown step-by-step how to write local shellcode for use on 64-Bit Linux systems. Shellcode is simple code, usually written in assembly that is used as payload in exploits such as buffer overflow attacks. Payloads are the arrow head of an exploit: though the rest of the arrow is important for the delivery of the attack, the arrow head deals the killing blow. In reality, payloads are slightly less exciting yet far more interesting and intelligent than medieva...

News: Apple's iOS 13.1 Public Beta 4 Available for iPhone

It's a strange time for us iOS beta testers. While Apple prepares for the general release of iOS 13 on Thursday, it's also beta testing that software's successor, iOS 13.1. An iPhone updated to iOS 13 on Sept. 19 will only have 11 days before seeing 13.1 in its Software Update page on Sept. 30. To prepare for this release, Apple released the fourth iOS 13.1 public beta, just about the same time as its developer counterpart.

News: Apple Just Released iOS 13.1 Developer Beta 4 for iPhone

Apple's iOS 13 is nearly here. After four months of beta testing, the latest iPhone software update promises over 200 brand new features, like system-wide dark mode and an overhauled Reminders app. That said, it'll be shortlived, as Apple plans to release iOS 13.1 as a supplemental update just 11 days later. In fact, the company just seeded developers the fourth beta for iOS 13.1 today, Sept. 18.

It's a big day for Apple. First, the company announced its new suite of phones: iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. Then, we get the iOS 13 Golden Master, the beta version of iOS 13 that will eventually release to the general public on Sept. 19. Now, it seems the company has dropped the third developer beta for iOS 13.1, set to release to all compatible iPhones on Sept. 30.

Steganography: How to Hide Secret Data Inside an Image or Audio File in Seconds

Steganography is the art of hiding information in plain sight, and in this tutorial, I'll show you how to use Steghide — a very simple command line tool to do just that. In addition, I'll go over a bit of conceptual background to help you understand what's going on behind the scenes. This is a tool that's simple, configurable, and only takes a few seconds to hide information in many file types.
