After installing Ubuntu as your primary OS, you should have protected against USB Rubber Ducky payloads, defended against hard drive forensics, and reduced the overall attack surface against physical strikes. When defending against network-based attacks, you'll want to minimize hardware disclosures, prevent packet sniffers, harden firewall rules, and much more.
It's a myth that regular users only need the protection of a virtual private network when on a public Wi-Fi connection. First, almost all network connections can be accessed without the proper permissions. Second, ethical hackers also need to think about using a VPN as one step to encrypting and protecting their activity and identity during pentests, phishing, and other actions.
Penetration testing, or pentesting, is the process of probing a network or system by simulating an attack, which is used to find vulnerabilities that could be exploited by a malicious actor. The main goal of a pentest is to identify security holes and weaknesses so that the organization being tested can fix any potential issues. In a professional penetration test, there are six phases you should know.
File permissions can get tricky on Linux and can be a valuable avenue of attack during privilege escalation if things aren't configured correctly. SUID binaries can often be an easy path to root, but sifting through all of the defaults can be a massive waste of time. Luckily, there's a simple script that can sort things out for us.
An attacker can repurpose public MyBB forums to act as command-and-control servers. It only takes a few lines of code to configure a MacBook to fetch commands and send responses to any website the attacker desires.
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.
UnrealIRCd is an open-source IRC server that has been around since 1999 and is perhaps the most widely used one today. Version 3.2.8.1 was vulnerable to remote code execution due to a backdoor in the software. Today, we will be exploiting the vulnerability with Metasploit, examining the underlying code to understand it, and creating our own version of the exploit in Python.
While SSH is a powerful tool for controlling a computer remotely, not all applications can be run over the command line. Some apps (like Firefox) and hacking tools (like Airgeddon) require opening multiple X windows to function, which can be accomplished by taking advantage of built-in graphical X forwarding for SSH.
Social media accounts are a favorite target for hackers, and the most effective tactics for attacking accounts on websites like Facebook, Instagram, and Twitter are often based on phishing. These password-stealing attacks rely on tricking users into entering their passwords into a convincing fake webpage, and they have become increasingly easy to make thanks to tools like BlackEye.
Particular vulnerabilities and exploits come along and make headlines with their catchy names and impressive potential for damage. EternalBlue is one of those exploits. Originally tied to the NSA, this zero-day exploited a flaw in the SMB protocol, affecting many Windows machines and wreaking havoc everywhere. Here, we will use EternalBlue to exploit SMB via Metasploit.
When joining a new network, computers use the Address Resolution Protocol to discover the MAC address of other devices on the same network. A hacker can take advantage of ARP messages to silently discover the MAC and IP address of network devices or actively scan the network with spoofed ARP requests.
Canary tokens are customizable tracking links useful for learning about who is clicking on a link and where it's being shared. Thanks to the way many apps fetch a URL preview for links shared in private chats, canary tokens can even phone home when someone checks a private chat without clicking the link. Canary tokens come in several useful types and can be used even through URL shorteners.
The ability to stay organized and be resourceful with data gathered from recon is one of the things that separates the true hackers from the script kiddies. Metasploit contains a built-in database that allows for efficient storage of information and the ability to utilize that information to better understand the target, which ultimately leads to more successful exploitation.
Conducting phishing campaigns and hosting Metasploit sessions from a trusted VPS is important to any professional security researcher, pentester, or white hat hacker. However, the options are quite limited since most providers have zero-tolerance policies for any kind of hacking, good or bad. After researching dozens of products, we came out with 5 potentials that are ideal for Null Byte readers.
Whether you're white hat, black hat, or some shade in-between, navigating through a network is a core part of hacking. To do that, we need to be able to explore a network to discover the addresses of gateways, interfaces, and other attached devices. When ifconfig just isn't enough, you can steer your way around a network with a convenient tool called Ship, the script for everything IP.
So much information exists online that it's easy to get lost in data while researching. Understanding the bigger picture can take a lot of time and energy, but narrowing the question to one that's easy to answer is the first step of any investigation. That's why analysts use open-source intelligence (OSINT) tools like Maltego — to help refine raw data into a complete understanding of a situation.
Hak5's products get a lot of attention. Popping up in popular shows like Mr. Robot, their hacking tools are bold proof of concepts with space built into the design for the community to add their own tweaks and modifications. On Friday, Oct. 27, Null Byte attended the Hak5 release event in San Francisco to check out their latest devices, including the new Packet Squirrel.
Equifax reported on Sept. 7 that it discovered a breach on July 29 which affects roughly half of Americans, many of whom don't realize they have dealings with the company. Hackers got away with social security numbers, addresses, and driver's license numbers, foreshadowing a "nuclear explosion of identity theft." Let's explore what really happened and what you and those around you can do to protect yourselves.
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 them stay current and speedy, and they can work on pretty much any computer, virtual machine, and cloud.
Have you ever used an open wifi, which after you connect displays a website to enter your credentials to get internet? That website is called captive portal and widely used in airports, hotels, universities etc. Have you ever wondered what would happen if someone would set up an open wifi with the same name displaying a very similar web page asking for credentials? Usually if there are multiple wifi networks with the same name and encryption, devices only display the one with the highest sign...
INTRODUCTION Hello dear null_byters here we go again with our third part of this serie.
Recently, I've been experimenting with BeEF (Browser Exploitation Framework), and to say the least, I'm hooked. When using BeEF, you must "hook" the victims browser. This means that you must run the script provided by BeEF, which is titled "hook.js", in the victims browser. Once you've done that, you can run commands against the victims browser and cause all kinds of mayhem. Among these commands, there is an option to use the victims webcam. This is what we'll be doing here today, so, let's g...
hello my dear colleagues, I made a visit to nullbyte and found that there is not a complete tutorial about the google dorks, so I felt the need for this tutorial, and seeing that there are many newbies around, so here's a tutorial that will teach you how to use google to hack.
NOTICE: Ciuffy will be answering questions related to my articles on my behalf as I am very busy. Hope You Have Fun !!!
Today I am going to teach the various ways that you can use social engineering to hack a system. For those of you that have followed my past tutorials, you know that social engineering can unlock a world of possibilities. This is because no matter how many firewalls, no matter how many patches there are on a server, the password is kept in the minds of people...and people, are not as smart as computers.
Welcome back, my future hackers! After my first tutorial about doxing, I decided I would dive a little bit deeper into the world of social engineering. In this tutorial we will learn some basic social engineering techniques to get into a company building, find out more information about the company's security, and maybe even exploit the company's computers if you get the chance.
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 hacker novitiates! When we are trying to find vulnerabilities in a website to attack, we need a solid web server vulnerability scanner. Internet-facing web apps can open enormous opportunities for us as they are often riven with vulnerabilities and can often offer an entire point to the internal network and resources.
Welcome back, my rookie hackers! Most often, the professional hacker is seeking protected information from the target system or network. This might be credit card numbers, personally identifiable information, or intellectual property (formulas, plans, blueprints, designs, etc.). Most of my Null Byte guides have been focused on getting into the system, but this only begs the question—"what do I do when I get there?"
Welcome back, my aspiring hackers! Those of you who've been reading my tutorials for some time now know that I am adamant regarding the necessity of learning and using Linux to hack. There is no substitute, period.
Welcome back, my fledgling hackers! A short while ago, I did a tutorial on conducting passive OS fingerprinting with p0f. As you remember, p0f is different from other operating system fingerprinting tools as it does not send any packets to the target, instead it simply takes packets off the wire and examines them to determine the operating system that sent them.
Despite the security concerns that have plagued Facebook for years, most people are sticking around and new members keep on joining. This has led Facebook to break records numbers with over 1.94 billion monthly active users, as of March 2017 — and around 1.28 billion daily active users.
In the first part of this series, we took a factual and technical look at the history of the Internet. I explained how all of these wires and servers got here in the first place. Obviously, a firm did not just create and build the Internet around 1995! Now that we know how the Internet came to be, we can get into the really fun stuff—what the Internet looks like now! Well, that's not quite the network design I was talking about, but it does show what the Internet looked like back in 2007 befo...
Web applications are ubiquitous in the modern online world, and knowing how to attack them is an increasingly valuable skill. But the key to a successful attack is good recon since it's easier to be focused and efficient with the more information you have. There are many fingerprinting tools available, such as httprint and WebTech, but there are even more that can aid us in reconnaissance.
There are countless tutorials online that show how to use Netstat and Tasklist to find an intruder on your computer. But with a few PowerShell functions, it's possible for a hacker to evade detection from the almighty command line.
Hackers often find fascinating files in the most ordinary of places, one of those being FTP servers. Sometimes, luck will prevail, and anonymous logins will be enabled, meaning anyone can just log in. But more often than not, a valid username and password will be required. But there are several methods to brute-force FTP credentials and gain server access.
Your social security number, credit card information, and medical history can fall into the wrong hands if you're not careful about how and where you share your data online. If you really care about your data, there are tools and techniques you can utilize to protect yourself from cyberstalkers, advertisers, and hackers in a time when digital lives are a high commodity.
If you've wanted to get into Wi-Fi hacking, you might have noticed that it can be pretty challenging to find a safe and legal target to hack. But you can easily create your own test network using a single ESP8266-based microcontroller like the D1 Mini.
