Welcome back, my aspiring hackers! Although this article may have been better placed first in this series, I doubt that anyone would have read it when just starting out studying Linux. Now, that you are well into your Linux studies and have some familiarity with how it operates, I'd like to take this moment to explain the philosophy around the Linux operating system.
Welcome back, my greenhorn hackers! As hackers, we often take for granted that nearly all of our hacking tools and operating system are free and open source. I think it's important to examine a bit of background on how we arrived at this intriguing juncture in the history of computer software. After all, we pay for nearly all of our other software (Microsoft, Adobe, etc.) and nearly everything else we use in life, so how is it that Linux and all our hacking tools are free?
Welcome back, my greenhorn hackers!
Welcome back, my hacker novitiates! Every so often, a MAJOR vulnerability appears that makes millions of systems vulnerable to attack. The most recent, named Shellshock, basically leaves every Mac OS X, Linux, and UNIX system on the planet vulnerable. As nearly two-thirds of all web servers on planet Earth run one of these operating systems (primarily Linux), that's a whole lot of systems out there waiting to be harvested.
Welcome back, my tenderfoot hackers! I have written many tutorials on hacking using Metasploit, including leaving no evidence behind and exploring the inner architecture. Also, there are my Metasploit cheat sheets for commands and hacking scripts.
Welcome back, my aspiring hackers! In recent tutorials, I have made reference to the name and location of the Linux devices in the file system, such as sda (first SATA or SCSI drive). Specifically, I have mentioned the way that Linux designates hard drives when making an image of a hard drive for forensic purposes.
Welcome back, my hackers novitiates! As you read my various hacking tutorials, you're probably asking yourself, "What are the chances that this hack will be detected and that I'll land behind bars, disappointing my dear mother who already thinks I'm a loser?"
In my first installment in this series on professional hacking tools, we downloaded and installed Metasploit, the exploitation framework. Now, we will begin to explore the Metasploit Framework and initiate a tried and true hack.
The ESP32-CAM is a convenient little camera module with a lot of built-in power, and you can turn one into an inconspicuous spy camera to hide in any room. There's only one issue: it does omit a USB port. That makes it a little harder to program, but with an ESP32-based board, FTDI programmer, and some jumper wires, you'll have a programmed ESP32 Wi-Fi spy camera in no time.
No longer strictly relegated to the realm of science fiction shows and novels, artificial intelligence can be found behind important technologies that are driving innovation throughout the world. From space exploration and self-driving cars to data science and marketing algorithms, AI is the driving force behind many technologies that are moving humanity forward.
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.
A macOS computer can reveal a lot of information about the owner, including which Wi-Fi network they have permission to access. With an Arduino-based attack, we'll use a five-dollar setup to inject a rogue Wi-Fi network and steal the list of trusted Wi-Fi networks, allowing us to see where the computer has been.
The internet has undoubtedly changed the way we work and communicate. With technological advances, more and more people can collaborate on the web from anywhere in the world. But this remote-friendly environment inherently brings security risks, and hackers are always finding ways to exploit systems for other uses.
Individually addressable LEDs, also commonly called "NeoPixels" after the popular Adafruit product, are a bright and colorful way to get started with basic Python programming. With an inexpensive ESP8266 or ESP32 microcontroller, it's easy to get started programming your own holiday lighting animations on a string of NeoPixels with beginner-friendly MicroPython!
Search engines index websites on the web so you can find them more efficiently, and the same is true for internet-connected devices. Shodan indexes devices like webcams, printers, and even industrial controls into one easy-to-search database, giving hackers access to vulnerable devices online across the globe. And you can search its database via its website or command-line library.
Apple's Gatekeeper security software for macOS (Mac OS X) is vulnerable to remote attacks up to version 10.14.5. An attacker that's anywhere in the world can exploit MacBooks and other Mac computers by sharing a single ZIP file.
MouseJack vulnerabilities were disclosed over three years ago. Some wireless keyboard manufacturers have since issued firmware updates, but millions (if not billions) of keyboards remain unpatched worldwide, either because they can't be updated or because the manufacturer never bothered to issue one.
Smartphones and laptops are constantly sending Wi-Fi radio signals, and many of these signals can be used to track us. In this guide, we'll program a cheap IoT device in Arduino to create hundreds of fake networks with common names; This will cause nearby devices to reveal their real trackable MAC address, and it can even let an attacker take over the phone's data connection with no warning.
Most companies have services like employee login portals, internal-only subdomains, and test servers they would prefer to keep private. Red teams and white hat hackers can find these obscure and often vulnerable services using a tool designed to help protect users from fraudulent certificates.
Kali Linux, by default, probably doesn't have everything you need to get you through day-to-day penetration testing with ease. With a few tips, tricks, and applications, we can quickly get started using Kali like a professional white hat.
Web 2.0 technology has provided a convenient way to post videos online, keep up with old friends on social media, and even bank from the comfort of your web browser. But when applications are poorly designed or incorrectly configured, certain flaws can be exploited. One such flaw, known as CSRF, allows an attacker to use a legitimate user's session to execute unauthorized requests to the server.
Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
Electronic warfare tactics work by jamming, disrupting, or disabling the technology a target uses to perform a critical function, and IoT devices are especially vulnerable to attacks. Wireless security cameras like the Nest Cam are frequently used to secure critical locations, but a hacker can surgically disable a webcam or other Wi-Fi connected device without disturbing the rest of the network.
It's easy to run Kali Linux from a live USB on nearly any available computer, but many publicly accessible laptops and desktops will be locked down to prevent such use. School, work, or library PCs can be secured with a BIOS password, which is often an easily recovered default password. Once you have access, though, you can use a USB flash drive to run Kali live on any PC you find.
With the macOS stager created and the attacker's system hosting the Empire listener, the malicious AppleScript can be designed and disguised to appear as a legitimate PDF using a few Unicode and icon manipulation tricks.
With an ordinary birthday card, we can introduce a physical device which contains malicious files into someone's home and deceive them into inserting the device into a computer.
Configuring onion services for the first time can be tricky. A surprising number of system administrators make seemingly trivial mistakes that ultimately lead to catastrophic cases of de-anonymizing supposedly anonymous sites on the dark web. OnionScan is a tool designed to identify common misconfigurations in onion services and aid us in understanding how to fix them.
Internet Relay Chat, or IRC, is one of the most popular chat protocols on the internet. The technology can be connected to the Tor network to create an anonymous and secure chatroom — without the use of public IP addresses.
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 flash drive, to deploy ransomware on a victim's computer within seconds. With an attack that only takes a moment, you'll need to know how to defend yourself.
Barrow's article on Pupy made me wish for a RAT that could target an OS frequently used by gatekeepers at startups, tech companies, and creative firms: macOS. Once run, a RAT can do severe damage by dumping a user's stored credentials for many accounts. The best loot lives in the Chrome Password cache, and EvilOSX, an OS X RAT, infiltrates macOS and dumps these credentials.
Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time.
While the USB Rubber Ducky is well known by hackers as a tool for quick in-person keystroke injection attacks, one of the original uses for it was automation. In this guide, I'll be going the latter, explaining how we can use it to automate Wi-Fi handshake harvesting on the Raspberry Pi without using a screen or any other input.
As pentesters and hackers, we're going to be working with text frequently — wordlists, configuration files, etc. A lot of this we'll be doing on our machine, where we have access to whatever editor we prefer. The rest of it will be on remote machines, where the tools for editing will be limited. If nano is installed, we have an easy-to-use terminal text editor, but it isn't very powerful.
Gaining access to a system is always exciting, but where do you go from there? Root or bust. Sure, a compromised host is a great way to run a botnet, or do some other boring, nefarious thing—but as hackers, we want root. We also want to take the easiest path possible, search out low-hanging fruit, and exploit them. SUID programs are the lowest of the low-hanging fruit.
Welcome back my networking geeks. In this part we are going to keep discussing about IP Addressing and I hope after you finish reading it you will become an IP wizzard.
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...
Welcome back, my aspiring hackers! In many of my earlier tutorials, I mentioned the complementary nature of hacking and forensics. Both disciplines, hacking and forensics, benefit from a knowledge of the other. In many cases, both disciplines will use the same tool. In this tutorial, we will use another tool that can be used in either discipline—Sysinternals—a suite of tools developed by Mark Russinovich.
Welcome back, my tenderfoot hackers! This is the third installment of my series on basic Linux skills that every hacker should know. Although some hacking tools are available for Windows and Mac, every real hacker uses Linux—for good reason.
