Welcome back, my novice hackers! In my series on cracking passwords, I began by showing off some basic password-cracking principles; developed an efficient password-cracking strategy; demonstrated how to use Hashcat, one of the most powerful password-cracking programs; and showed how to create a custom wordlist using Crunch. In this tutorial, I will show you how to create a custom wordlist based upon the industry or business of the targets using CeWL.
Greetings all. Before I get into the tutorial, I would like to mention that I am fairly new to Null Byte (been lurking for some time though), and what really appeals to me about this place is its tight, family-like community where everyone is always willing to help each other and the constant search for knowledge that inhabits this subdomain is a driving motivator for me to join in. I'm glad I arrived at the right time. Anyway, wipes tears (not really)...
Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Using the Mentalist, we can generate millions of likely passwords based on details about the target.
Password cracking is a specialty of some hackers, and it's often thought that raw computing power trumps everything else. That is true in some cases, but sometimes it's more about the wordlist. Making a custom, targeted wordlist can cut down cracking time considerably, and Wordlister can help with that.
Welcome back, my apprentice hackers! In this series on password cracking, I have been attempting to develop your skills in the age-old art of password cracking. Although it might seem like a simple and straightforward exercise, those of you who have attempted password cracking know that there are many subtleties to this art.
To name just a few companies, VK, µTorrent, and ClixSense all suffered significant data breaches at some point in the past. The leaked password databases from those and other online sites can be used to understand better how human-passwords are created and increase a hacker's success when performing brute-force attacks.
Greetings fellow hackers. This tutorial is about creating "safe" passwords. This is different from strong passwords. Safe passwords is just creating a password that is not used by someone else or colleague, my definition. But how do you prevent something like this from happening? Of course you won't ask your friend if s|he is using the password you are about to create. Before I show you some of my tele-psychic powers like Professor Xavier, you might want to read this for advice on creating "s...
hey everyone ,im a newbie here at null byte and i want to say thanks for all the tutorials and information people give me here.
Router gateways are responsible for protecting every aspect of a network's configuration. With unfettered access to these privileged configurations, an attacker on a compromised Wi-Fi network can perform a wide variety of advanced attacks.
Using Hydra, Ncrack, and other brute-forcing tools to crack passwords for the first time can be frustrating and confusing. To ease into the process, let's discuss automating and optimizing brute-force attacks for potentially vulnerable services such as SMTP, SSH, IMAP, and FTP discovered by Nmap, a popular network scanning utility.
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.
Hi, my name is Alan, and I am not a script kiddy brat from Xbox Live asking you how to boot someone offline for being mean to me. I am an amateur white hat hacker hoping to learn and teach and this is my first tutorial.
Welcome back, my greenhorn hackers! Continuing with my series on how to crack passwords, I now want to introduce you to one of the newest and best designed password crackers out there—hashcat. The beauty of hashcat is in its design, which focuses on speed and versatility. It enables us to crack multiple types of hashes, in multiple ways, very fast.
Welcome back, my tenderfoot hackers! As you know, DNS, or Domain Name System, is critical to the operation of the Internet. It provides us with the ability to type in domain names such as www.wonderhowto.com rather than the IP address. This simple service saves us from having to memorize thousands of our favorite website IP addresses. Instead, we simply type in a domain name to retrieve the website.
Welcome back, my hacker novitiates! Often, to hack a website, we need to connect to and exploit a particular object within said website. It might be an admin panel or a subdirectory that is vulnerable to attack. The key, of course, is to find these objects, as they may be hidden.
Welcome back, my hacker novitiates! In an earlier tutorial, I had introduced you to two essential tools for cracking online passwords—Tamper Data and THC-Hydra. In that guide, I promised to follow up with another tutorial on how to use THC-Hydra against web forms, so here we go. Although you can use Tamper Data for this purpose, I want to introduce you to another tool that is built into Kali, Burp Suite.
Word games can expand your vocabulary skills in all sorts of exciting and creative ways. Because of this, both the iOS App Store and the Google Play Store are awash with word games, making it hard to differentiate between good and bad titles. This is especially troublesome if you're looking to purchase a game, as everyone hates to waste hard-earned cash.
A powered-off MacBook can be compromised in less than three minutes. With just a few commands, it's possible for a hacker to extract a target's password hash and crack it without their knowledge.
Don't think because your MacBook is using FileVault disk encryption your device is secure or immune to hackers. Here's how to find out if that FileVault password is strong enough to withstand an attack from a motivated attacker.
Everybody knows not to store sensitive information in unencrypted files, right? PDFs and ZIP files can often contain a treasure trove of information, such as network diagrams, IP addresses, and login credentials. Sometimes, even certain files that are encrypted aren't safe from attackers. That's where Zydra comes in — a tool for cracking RAR files, ZIP files, PDF files, and Linux shadow files.
Cross-site scripting is one of the most common vulnerabilities found on the web today, with repercussions of this type of flaw ranging from harmless defacement to sensitive data exposure. Probing for XSS can be tedious and time-consuming for an attacker, but luckily there are tools available to make things a little easier, including Burp Suite, Wfuzz, and XSStrike.
Compromised uTorrent clients can be abused to download a malicious torrent file. The malicious file is designed to embed a persistent backdoor and execute when Windows 10 reboots, granting the attacker remote access to the operating system at will.
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.
Greetings all. I'm back with another informational review of the diversity of utilities for use in the sphere of hacking at your disposal. Today we are going to cover the insides of CUPP (Common User Passwords Profiler) in its entirety. The tool is very basic in nature, as there is little to no configuration needed to get cracking (worst pun ever). So let's get started, shall we?
Welcome back, my novice hackers! Before we try to attack a website, it's worthwhile understanding the structure, directories, and files that the website uses. In this way, we can begin to map an attack strategy that will be most effective.
After gaining access to a root account, the next order of business is using that power to do something more significant. If the user passwords on the system can be obtained and cracked, an attacker can use them to pivot to other machines if the login is the same across systems. There are two tried-and-true password cracking tools that can accomplish this: John the Ripper and Hashcat.
Hi there again, aspiring hackers (and veterans as well)! I'm going to explain how to perform a dictionary attack on a WPA/WPA2 protected network with Wifite. Please note that this doesn't work with WPA Enterprise For that end, you'd have to use an Evil Twin to get the "Enterprise" auth attempt, and then crack it.
Welcome back, my novice hackers! In a recent tutorial, I showed how the SNMP protocol can be a gold mine of information for reconnaissance on a potential target. If you haven't already, I strongly suggest that you read it before progressing here, as little of this will make much sense without that background.
Hashes containing login passwords are transmitted between Windows computers on local Wi-Fi networks. By intercepting and decrypting these hashes using Responder and John the Ripper, respectively, we can learn a target's login credentials which can be later used to gain physical access to their computer.
Hacking web applications can sometimes be challenging due to the sheer amount of moving parts they possess. At the core of these apps are HTTP requests and parameters, but these things are often concealed from the user, due to security reasons, convenience, or both. However, a tool called Arjun can be used to discover hidden HTTP parameters in web apps.
One of the first steps in attacking a web application is enumerating hidden directories and files. Doing so can often yield valuable information that makes it easier to execute a precise attack, leaving less room for errors and wasted time. There are many tools available to do this, but not all of them are created equally. Gobuster, a directory scanner written in Go, is definitely worth exploring.
Welcome, my hacker novitiates! As part of my series on hacking Wi-Fi, I want to demonstrate another excellent piece of hacking software for cracking WPA2-PSK passwords. In my last post, we cracked WPA2 using aircrack-ng. In this tutorial, we'll use a piece of software developed by wireless security researcher Joshua Wright called cowpatty (often stylized as coWPAtty). This app simplifies and speeds up the dictionary/hybrid attack against WPA2 passwords, so let's get to it!
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 tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.
One of the first steps when pentesting a website should be scanning for hidden directories. It is essential for finding valuable information or potential attack vectors that might otherwise be unseen on the public-facing site. There are many tools out there that will perform the brute-forcing process, but not all are created equally.
In the second part of this tutorial, we are going to crack the hashes that we've captured previously. I'm going to explain how to do it with the powerful John the Ripper. It comes with Kali by default, so no need to install!
Welcome back, my tenderfoot hackers! In this series, we are exploring the myriad of ways to hack web applications. As you know, web applications are those apps that run the websites of everything from your next door neighbor, to the all-powerful financial institutions that run the world. Each of these applications is vulnerable to attack, but not all in the same way.
Welcome back, my hacker apprentices! Last week, I started off my password cracking series with an introduction on the principles and technologies involved in the art of cracking passwords. In past guides, I showed some specific tools and techniques for cracking Windows, online, Wi-Fi, Linux, and even SNMP passwords. This series is intended to help you hone your skills in each of these areas and expand into some, as yet, untouched areas.
The art of fuzzing is a vital skill for any penetration tester or hacker to possess. The faster you fuzz, and the more efficiently you are at doing it, the closer you come to achieving your goal, whether that means finding a valid bug or discovering an initial attack vector. A tool called ffuf comes in handy to help speed things along and fuzz for parameters, directors, and more.
There are many password-cracking tools out there, but one of the mainstays has always been John the Ripper. It's a powerful piece of software that can be configured and used in many different ways. Metasploit actually contains a little-known module version of JTR that can be used to quickly crack weak passwords, so let's explore it in an attempt to save precious time and effort.
