As penetration testers, we sometimes need to securely store customer data for prolonged periods. Bruteforce-resistant, vault-like containers can be created with just a few commands to protect ourselves from physical attacks and unintended data disclosures.
Due to weaknesses in the way Wi-Fi works, it's extremely easy to disrupt most Wi-Fi networks using tools that forge deauthentication packets. The ease with which these common tools can jam networks is only matched by how simple they are to detect for anyone listening for them. We'll use Wireshark to discover a Wi-Fi attack in progress and determine which tool the attacker is using.
Most users don't realize how much valuable data is in their network traffic. With a few simple tools, an attacker can quickly pick out cookies, passwords, and DNS queries from a macOS device as it covertly streams the victim's network traffic to the attacker's system. Here, we will cover two methods for analyzing packets flowing from a Mac.
Web application vulnerabilities are one of the most crucial points of consideration in any penetration test or security evaluation. While some security areas require a home network or computer for testing, creating a test website to learn web app security requires a slightly different approach. For a safe environment to learn about web app hacking, the OWASP Juice Shop can help.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
While there are a variety of privacy-focused search engines available like StartPage and DuckDuckGo, nothing can offer the complete trust offered by creating one's own search engine. For complete trust and security, Searx can be used as free metasearch engine which can be hosted locally and index results from over 70 different search engines.
While the security behind WEP networks was broken in 2005, modern tools have made cracking them incredibly simple. In densely populated areas, WEP networks can be found in surprising and important places to this day, and they can be cracked in a matter of minutes. We'll show you how a hacker would do so and explain why they should be careful to avoid hacking into a honeypot.
Local port forwarding is good when you want to use SSH to pivot into a non-routable network. But if you want to access services on a network when you can't configure port-forwarding on a router and don't have VPN access to the network, remote port forwarding is the way to go.
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.
The threat of an evil access point has been around for a long time, and with the rise of open public Wi-Fi, that threat is often overshadowed by how comfortable we are using third-party Wi-Fi hotspots at coffee shops and public spaces. While we've shown an evil twin attack using the Aircrack-ng suite of tools, MitmAP is a Python tool to configure custom APs for many types of wireless attacks.
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.
Despite concerns with SafetyNet, Google actually cares about root. Every phone they sell has an unlockable bootloader, so you can toggle a setting and send a Fastboot command, then start flashing custom firmware right away. The Pixel 2 and Pixel 2 XL continue this tradition, and now they have an official root method.
There are more than 2 billion Android devices active each month, any of which can be hacked with the use of a remote administration tool, more commonly known as a RAT. AhMyth, one of these powerful tools, can help outsiders monitor a device's location, see SMS messages, take camera snapshots, and even record with the microphone without the user knowing.
Some of us woke up at the KRACK of dawn to begin reading about the latest serious vulnerability that impacts the vast majority of users on Wi-Fi. If you weren't one of those early readers, I'm talking about the Key Reinstallation Attack, which affects nearly all Wi-Fi devices.
Tor is an excellent obfuscation network for web traffic, and while instant messaging over the network is very useful, it can be relatively difficult to configure. In this guide, we'll look at two synchronous communications platforms (instant messengers) which can be routed over the Tor network, Ricochet and XMPP.
Recently, I ran across SecGen, a project which allows a user to create random vulnerable machines. I absolutely love vulnerable machines, since a vulnerable VM is a safe and legal way to practice hacking tactics, test out new tools, and exercise your puzzle-solving skills.
In my previous article, I discussed installing and configuring OpenVAS on Kali Linux. Now it's time to start using OpenVAS with the Greenbone Security Assistant to audit networks for security issues. This can be extremely helpful when you are looking for vulnerabilities or misconfigurations in a large number of hosts.
A router is the core of anyone's internet experience, but most people don't spend much time setting up this critical piece of hardware. Old firmware, default passwords, and other configuration issues continue to haunt many organizations. Exploiting the poor, neglected computer inside these routers has become so popular and easy that automated tools have been created to make the process a breeze.
It's no secret that devices leak data, but sometimes they do so in ways you may not expect. Your phone, laptop, printer, and IOT devices leak Wi-Fi information that can (and is) used to track you.
Google's Pixel phones claimed the top spot in our ranking of the best phones for rooting, but they do have one drawback from a modder's perspective: Because of their A/B partition layout for seamless updates, the devices don't have official support for Magisk. Thankfully, though, developer goodwin has stepped in with a fix, so we can now get Magisk working on the Pixel and Pixel XL.
The OnePlus 3 and 3T are two of the most modder-friendly devices to be released in 2016. Not only that, but they're both extremely solid phones which happen to sport a very reasonable price tag. Among the things that make these devices such a joy for tinkerers is the fact that they have an unlockable bootloader, receive timely kernel source releases, and are actually quite easy to root.
Welcome back, my hacker novitiates! If you have been following this new Snort series, you know that Snort is the world's most widely used intrusion detection/protection system. Now a part of the world's largest network equipment company, Cisco, it is likely to be found everywhere in one form or another. This makes a compelling argument for learning how to use it, as it will likely be a necessity in any security-related position.
Welcome back, my tenderfoot hackers! As you should know from before, Snort is the most widely deployed intrusion detection system (IDS) in the world, and every hacker and IT security professional should be familiar with it. Hackers need to understand it for evasion, and IT security professionals to prevent intrusions. So a basic understanding of this ubiquitous IDS is crucial.
Welcome back, my neophyte hackers! In the world of information security, the most common intrusion detection system (IDS) you will ever encounter is Snort. As you probably already know, an IDS works similarly to antivirus (AV) software on your desktop; It attempts to identify malicious software on your network and warns you of its presence.
In my last tutorial, I talked about creating a virus inside of a Word Document in the scenario of a mass-mailer attack. In this post, however, I'm going to be covering creating a fake image or screenshot with a meterpreter backdoor hidden inside to be used in a similar scenario. Step 1: Creating the Virus
Welcome back, my novice hackers! In this series, we have been exploring how a forensic investigator can find evidence of illegal or illicit activity. Among other things, we have examined the registry and prefetch files for artifacts and have done some rudimentary forensic analysis. For those of you who are seeking career as a forensic investigator or security engineer, this can be invaluable training. For hackers, it might be life-saving.
Greetings my fellow hackers.
When performing something such as a mass mailer attack on a company, sending executables usually isn't the best option. That's why, in this tutorial, I'll be teaching you how to code a VBA script macro into a Word document in order to compromise a system. Combined with a little social engineering, this can be a very effective technique.
Many of our members here at Null Byte are aspiring hackers looking to gain skills and credentials to enter the most-valued profession of the 21st century. Hackers are being hired by IT security firms, antivirus developers, national military and espionage organizations, private detectives, and many other organizations.
Social engineering is a pretty important item in a hacker's toolkit. In Mr robot there was a time, we saw Elliot using social engineering to gain access to his therapist's boyfriend's email and bank accounts by calling him and pretending to be someone from his bank, then Elliot asked him for some info that were really useful to gain access to his account, the target believed to be someone from the bank and gave him the info Elliot was looking for. But How Is It in the Real World?
As one of the most powerful Android apps for connecting your phone or tablet to your other devices in various ways, Pushbullet had always been a fan—and Gadget Hacks—favorite.
Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on OS X (it has several more commands/options), but I think it is still worth noting how to do it. I've even seen some people mistakenly say that Meterpreter can only be run on Windows, which is not true. Meterpreter can ea...
Welcome back, my tenderfoot hackers! Well, the first season of Mr. Robot just ended and Elliot and fsociety successfully took down Evil Corp! They have effectively destroyed over 70% of the world's consumer and student debt! Free at last! Free at last! Of course, global financial markets crashed as well, but that's another story.
Firstly let me start by giving credit to Lucid for their guide on Evilzone which inspired this idea, as well as the recent talk of anonymity on here.
Welcome back, my novice hackers! In this third installment of my Hacking Web Apps series, we will look at the authentication of web applications. Remember, there are many ways to hack web applications (as I pointed out in my first article), and cracking authentication is just one method.
Welcome back, my tenderfoot hackers! As hackers, we often are required to get past antivirus (AV) software or other security measures. To do so effectively, we need to have some understanding of how AV software works. In this tutorial, we will take a cursory view of how AV software works so that you can better strategize on how to evade detection by it.
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...
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.
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.
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.
