When you get a new phone, the last thing you want to deal with is a ton of preinstalled programs staring back at you. They not only clutter your home screen with apps you'll probably never use, but they're also wasting space on your internal storage and potentially draining ba ...more
Welcome back, my rookie hackers! When Wi-Fi was first developed and popularized in the late '90s, security was not a major concern. Unlike wired connections, anyone could simply connect to a Wi-Fi access point (AP) and steal bandwidth, or worse—sniff the traffic. The first a ...more
In 2019, the Raspberry Pi 4 was released with specs including either 1 GB, 2 GB, or 4 GB of memory, a Broadcom BCM2711B0 quad-core A72 SoC, a USB Type-C power supply, and dual Micro-HDMI outputs. Performance and hardware changes aside, the Pi 4 Model B runs Kali Linux just as ...more
During a penetration test, one of the most important aspects of engaging a target is information gathering. The more information you have coming into an attack, the more likely the attack is to succeed. In this article, I'll be looking at SpiderFoot, a modular cross-platform O ...more
A long time ago, we recommended the Hover Zoom extension for Chrome as an easy way to blow up small image thumbnails without actually have to "click" on the images themselves. Over the past year, there have been reports that Hover Zoom now collects and sells your browsing data ...more

Windows 10 passwords stored as NTLM hashes can be dumped and exfiltrated to an attacker's system in seconds. The hashes can be very easily brute-forced and cracked to reveal the passwords in plaintext using a combination of tools, including Mimikatz, ProcDump, John the Ripper, ...more
A man-in-the-middle attack, or MitM attack, is when a hacker gets on a network and forces all nearby devices to connect to their machine directly. This lets them spy on traffic and even modify certain things. Bettercap is one tool that can be used for these types of MitM attac ...more
A lot of time can be wasted performing trivial tasks over and over again, and it's especially true when it comes to hacking and penetration testing. Trying different shells to own a target, and testing out privilege escalation commands afterward, can eat up a lot of time. Fort ...more
Hello there Nullbyte users! This will be my first article here. Feel free to give feedback in the comments! Today I'll be introducing the UNIX text editor VIM. VIM is a text editor that is completely controlled from the keyboard. An experienced VIM user is A LOT faster than ...more

SSH is a powerful tool with more uses than simply logging into a server. This protocol, which stands for Secure Shell, provides X11 forwarding, port forwarding, secure file transfer, and more. Using SSH port forwarding on a compromised host with access to a restricted network ...more
Web applications are a prime target for hackers, but sometimes it's not just the web apps themselves that are vulnerable. Web management interfaces should be scrutinized just as hard as the apps they manage, especially when they contain some sort of upload functionality. By ex ...more
Containers are isolated software instances representing applications, servers, and even operating systems—complete with all of their dependencies, libraries configuration files, etc.—and they're taking over the corporate world. The ephemeral, portable nature of containers help ...more
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 — an ...more
Ports allow network and internet-connected devices to interact using specified channels. While servers with dedicated IP addresses can connect directly to the internet and make ports publicly available, a system behind a router on a local network may not be open to the rest of ...more
Ransomware is software that encrypts a victim's entire hard drive, blocking access to their files unless they pay a ransom to the attacker to get the decryption key. In this tutorial, you'll learn how easy it is to use the USB Rubber Ducky, which is disguised as an ordinary fl ...more
SSH, or the secure shell, is a way of controlling a computer remotely from a command-line interface. While the information exchanged in the SSH session is encrypted, it's easy to spy on an SSH session if you have access to the computer that's being logged in to. Using a tool c ...more
File inclusion can allow an attacker to view files on a remote host they shouldn't be able to see, and it can even allow the attacker to run code on a target. To demonstrate these vulnerabilities, we'll be practicing PHP file inclusion using the Damn Vulnerable Web App. We'll ...more
The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python to ...more
