Many operators use elevators to control access to particular floors, whether it be the penthouse at a hotel or a server room in an office building. However, the law requires them all to have a fire service mode, which gives emergency access to restricted floors, and a hacker can use that to bypass security altogether.
Developed by Open Whisper Systems, Signal is a free, open-source encrypted communications app for both mobile and desktop devices that allows users to make voice calls, send instant messages, and even make video calls securely. However, a vulnerability was recently discovered for the desktop version that can be turned into a USB Rubber Ducky payload to steal signal messages with a single click.
Thanks to its intuitive interface that makes sending and receiving money a breeze, Venmo has become the go-to app for millions in the US. In fact, you've probably heard the term "Venmo you" being tossed around between friends. But before you take the plunge and sign up, it's always a good idea to read the fine print and know what you're getting into. Money is involved, after all.
The conversation of which operating system is most secure, macOS vs. Windows, is an ongoing debate. Most will say macOS is more secure, but I'd like to weigh in by showing how to backdoor a MacBook in less than two minutes and maintain a persistent shell using tools already built into macOS.
Between the Cambridge Analytica scandal and the revelation that Facebook logs your calls and text history on Android, many are considering joining the #DeleteFacebook movement. But it can be difficult to leave the site, because so much of its content is only available to active users. If you want to keep in the loop without sacrificing your privacy, you'll want to follow the steps below.
Before you go ahead and delete your Facebook — don't lie, you've been thinking about it — consider this. Facebook offers users a wide variety of privacy options to mess with, which can help you find a little control over your information. We're not saying this solves Facebook's privacy crisis, but it might be a more reasonable option than throwing in the towel entirely.
After a hacker has configured Metasploit on a remote private server, created a resource script for automation, and created a simple payload, he or she can begin the process of remotely controlling someone's Windows 10 computer with just a few moments of physical access — even if the computer is off.
Now that we have our payload hosted on our VPS, as well as Metasploit installed, we can begin developing the webpage which will trick our "John Smith" target into opening our malicious file. Once he has, we can take over his computer.
Many guides on Null Byte require using the Secure Shell (SSH) to connect to a remote server. Unfortunately for beginners, learning to use SSH can become a confusing mix of third-party programs and native OS support. For Chrome OS users, using SSH is even more difficult. We'll fix this by using the Chrome Secure Shell to establish an SSH connection from any device that can run a Chrome browser.
With the addition of the OpenSSH client and server in the Windows 10 Fall Creators Update, you no longer have to rely on third-party programs to open an SSH server and connect to a Windows machine. While still a beta feature, this represents a long-overdue update fulfilling a promise made back in 2015.
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.
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.
In one of my previous articles, I discussed ShinoBot, a remote administration tool that makes itself obvious. The goal is to see if the user could detect a remote administration tool or RAT on their system. In this article, I'll be demonstrating the use of Pupy, an actual RAT, on a target Ubuntu 16.04 server.
Bluetooth Low Energy (BLE) is the de facto wireless protocol choice by many wearables developers, and much of the emerging internet of things (IoT) market. Thanks to it's near ubiquity in modern smartphones, tablets, and computers, BLE represents a large and frequently insecure attack surface. This surface can now be mapped with the use of Blue Hydra.
Hacking from a host machine without any form of proxying is reckless for a hacker, and in a penetration test, could lead to an important IP address becoming quickly blacklisted by the target. By routing all traffic over Tor and reducing the threat of malicious entrance and exit nodes with a VPN, we can configure Kali to become thoroughly private and anonymous.
In 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied together with the Gnome desktop environment. However, Kali Linux isn't the only penetration-testing distribution available.
The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data. Profile pictures, avatars, and image galleries are used all over the internet. While all images carry digital picture data — and many also carry metadata regarding camera or photo edits — it's far less expected that an image might actually be hiding malicious code.
The new iPhone X will be released on Friday, Nov. 3, in Apple Stores located in over 55 countries and territories. For those of you who would rather skip the in-stores lines that will start building well before the 8 a.m. local time openings, you can preorder the iPhone X on Friday, Oct. 27, starting at 12:01 a.m. PDT.
Are you interested in video editing, but have no background in it? Are you looking to put together a short from some clips you've shot, but don't know where to start? You could use iMovie, an application that comes free with every iPhone, but then what would you do on Android? There must be a universal solution that works across both iOS and Android to let you work however and wherever you like.
Tossing an old Android smartphone with a decent battery into your hacking kit can let you quickly map hundreds of vulnerable networks in your area just by walking or driving by them. The practice of wardriving uses a Wi-Fi network card and GPS receiver to stealthily discover and record the location and settings of any nearby routers, and your phone allows you to easily discover those with security issues.
Microsoft recently released "Seeing AI," an app aimed to help the blind understand their surroundings. As Microsoft puts it, "the app narrates the world around you by turning the visual world into an audible experience."
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.
Social engineering makes headlines because human behavior is often the weakest link of even well-defended targets. Automated social engineering tools can help reclusive hackers touch these techniques, but the study of how to hack human interactions in person is often ignored. Today, we will examine how to use subtle, hard to detect persuasion techniques to compromise a human target.
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.
One major component of Level 4 and Level 5 driverless cars is in very short supply. Venture capitalists and engineers from around the world are racing to fill the LiDAR production, price, and performance void.
In the music world, it's safe to say electric instruments are more versatile, but they lack the portability of their acoustic counterparts. However, with the aid of your smartphone plus an audio interface, you can play your electric instrument anywhere — with all the pedal effects you please — and even record your efforts.
The Galaxy S8 has finally touched down, and it's an absolutely gorgeous device. Samsung's brand new flagship comes jam-packed with new features — some refined, and some that aren't. Luckily, we've compiled some major features to help you get started as quickly as possible so you can go about the rest of your day and show off your shiny new S8 to friends and coworkers.
Beginners luck is a phrase I have always hated. But really, beginners luck comes down to not letting your experience in something get in the way of the idea.
All day I dream of eggs: scrambled, poached, over easy, hard-boiled, fried, baked, raw... Okay, the last one is a joke (unless you're Gaston, which means that you eat five dozen of them and you're roughly the size of a barge). But eggs are freaking good in just about any cooking prep, and more often than not are the foundation of your favorite baked goods.
Now that we've got all of our software installed, we're going to proceed with the next step in our HoloLens Dev 101 series—starting a fresh project and building it into a Holographic application. Then we will output the application to the HoloLens Emulator so we can see it in action.
After enabling disk encryption, creating encrypted disk images, installing KeePassX and iTerm2, and using Git with local repositories, the next step to getting your Mac computer ready for hacking is setting up a package manager that can install and update open-source hacking tools. There are multiple options to choose from, but Homebrew has a slight advantage.
With some of the groundwork out of the way in getting a Mac set up for hacking, it's time to start looking at toolboxes. Our first toolbox is Git, which will be used throughout future tutorials.
For years, smartphone makers have been caught up in a megapixel spec race to prove that their camera is better than the next guy's. But we've finally come to a point where even the lower-end camera phones are packing more megapixels than they need, so it's getting harder to differentiate camera hardware.
So you're finally ready to head out on that big trip you've been planning for months, huh? It's an exciting time, but there are plenty of things you'll need to prepare before you head out. For instance, it's hard to imagine life without a smartphone these days, and with useful traveling apps like Google Translate and maps, you'll almost have to make sure that you have a working smartphone when you arrive at your destination.
Greetings my fellow hackers, In the previous article, I discussed briefly about ransomwares and their devastating capabilities. Devastating in a way that ransomwares are not only known to encrypt files but to also lockout some specific functions of the system and hold it up for a ransom.
Welcome back, everybody. In the previous article, we covered the ideas and concepts of well-known ports and trust exploitation in order to evade a firewall. Today, we'll be building the shell, the part that receives commands, executes them, and sends the output back to the attacker.
Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...
Hello fellow Nullbytiens, today we will be talking about IRC again (if you haven't read OTW's post about head over there now)and more specifically about using 1 nickname with multiple devices or IRC clients.
Since Android is an open source operating system, that means anyone with a little know-how can download, view, and even alter its underlying code base. Manufacturers do it all the time, which is how we end up with skins like TouchWiz and Sense. But when Android's awesome third-party development community gets their hands on this code, we end up with custom ROMs like LineageOS and MIUI.
Greetings my fellow aspiring hackers, It's still Christmas and we have a lot of things and hugs and kisses and ... to share ( you know the things that you do ). I have never done this before but I just felt to encourage you on the quest for knowledge, security and defence, skills and a whole lot more that comes out as a result of pursuing hacking. What we mean by hacking on this forum is White hat Hacking and OTW has great articles on it and I don't need to explain myself on that one.
