There are nearly 100,000 unique onion service addresses online with over two million people using Tor every single day. Join me as I explore a small fraction of what the Tor network has to offer.
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.
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.
In the previous section of this series on dynamic user interfaces for HoloLens, we learned about delegates and events. At the same time we used those delegates and events to not only attach our menu system to the users gaze, but also to enable and disable the menu based on certain conditions. Now let's take that knowledge and build on it to make our menu system a bit more comfortable.
Tony Parisi, the global head of VR/AR at Unity Technologies, has been passionately working with virtual and immersive spaces for a long time. And while the internet world we live in now is very different than when Parisi was co-authoring VRML (Virtual Reality Modeling Language) — an early attempt at creating 3D environments that would work in a web browser — some of the questions that were assumed answered are being asked again.
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.
Hello null_byters, after some time out here we are again with another tutorial, continuing our beautiful series, today we will write our first real world bash script.
I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but when you're a kid, these can be important issues to you. So I slept with my glasses on every night, just in case. Photo from George Pal's The Time Machine.
A few weeks ago, Facebook published a blog post called "Proposed Updates to our Governing Documents," which outlines a few changes in their policies and user voting system. These changes would essentially take away users' right to vote on future changes to Facebook's data use policy while also taking away Facebook's responsibility to alert users of those changes. If the new policy is enacted, the vote will be replaced with "a system that leads to more meaningful feedback and engagement," what...
Apple Card has generated quite the buzz since its March 2019 announcement. The iPhone maker's new credit card pairs with Apple Wallet on your device, is simple to sign up for, includes enhanced security over other cards, has zero fees, and provides daily rewards right to your Apple Cash account. And as good as that sounds, the fine print can complicate things real quick.
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.
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.
The moment arrives when you finally pop a shell on the web server you've been working on, only you find yourself in a strange environment with limited functionality. Restricted shells are often used as an additional line of defense and can be frustrating for an attacker to stumble upon. But with enough patience and persistence, it is possible to escape these restricted environments.
Surprising? No. Exciting? Absolutely. After a grand introduction by at the Apple event on September 10, 2019, the iPhone 11 is finally here. We may have known nearly everything about this new iOS device ahead of time, thanks to the usual surge of reliable leaks and rumors.
So the new iPhones have arrived. Like last year, Apple released three iPhones in three different sizes that vary in price and specs. There's the base model iPhone 11, and then there are the real deal, premium models, the iPhone 11 Pro and Pro Max.
Every summer for the last 26 years, hoards of hackers have descended on the Las Vegas Strip for DEFCON, the biggest hacker conference in the US. There's a wealth of talks every season (DEFCON 27 has at least 95 scheduled), and there have been some essential topics to learn from in past discussions. We've dug through the last ten years and found the 15 most popular talks you should watch.
The macOS 10.14 security update tried to make parts of the operating system difficult for hackers to access. Let's take a closer look at how its new feature works and what we can do to spoof the origin of an application attempting to access protected data.
There's actually more to the dialer screen on your OnePlus than meets the eye. Besides its obvious purpose of calling people, there's a vast array of secret codes that you can input to troubleshoot your device, in addition to revealing important information, making anonymous phone calls, and so much more.
Coinhive, a JavaScript cryptocurrency miner, was reportedly discovered on the BlackBerry Mobile website. It was placed there by hackers who exploited a vulnerability in the site's e-commerce software that allowed them to anonymously mine cryptocurrency every time the website was viewed. There's no doubt Coinhive, an innovative mining method, is being abused and exploited by hackers in the wild.
While iOS 11.3 doesn't have as many new features as iOS 11.2, there's still a lot to love about Apple's latest update for iPad, iPhone, and iPod touch, even if some of the best features we were expecting didn't make the cut.
Shodan calls itself "the search engine for internet-connected devices." With so many devices connected to the internet featuring varying levels of security, the special capabilities of this search engine mean it can provide a list of devices to test and attack. In this tutorial, we'll use Python to target specific software vulnerabilities and extract vulnerable target IP addresses from Shodan.
Every time you make a call or send a text, you're giving the recipient your phone number. This can be quite the security vulnerability, opening yourself up to scammers, spammers, and the feds. In this how-to, we'll look at what a burner phone is, why you might want one, and how to get started using a free second phone number on your regular smartphone.
In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
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...
Cryptography is the science of keeping secrets, or more specifically, the science of disguising them. As a point of fact, cryptography has progressed quite a bit farther and now encompasses file and message integrity, sender authentication, and pseudo-random number generators.
Apple has completely redesigned its Calculator app for iPhone, and it's now powerful and practical enough to replace any third-party calculator you've been using.
If you have an iPhone running iOS 15 that's connected to Google Fi or another mobile virtual network operator, you may not be getting any photos or videos in Messages. That may be because you recently installed a software update, and you'll have to restore your cellular data network settings to get MMS working again.
The original iPhone SE was, for some, the perfect iPhone. It brought back the popular one-handed form factor of the iPhone 5 but packed in the internals of the then-new iPhone 6S. Now, the second-generation iPhone SE is here for 2020, but can it live up to what made the first-generation iPhone SE so popular?
Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal. Due to the way hashes work, not all are created equal. Some are more vulnerable than others, and a little Python could be used to brute-force any weak hashes to get the passwords they were created from.
Step 1: What Exploit Development Is and Why Should I Be Interested on About This Topic
Visual Voicemail revolutionized phone calls and the voicemail system when Apple introduced it with the original iPhone. Now, thanks to iOS 17, Apple has done it again with its newest calling feature, Live Voicemail. This feature uses speech-to-text technology to show you voicemail transcriptions on the incoming call screen in real time, helping you decide if it's important enough to answer the call.
There are two types of people in this world: those who recognize Wordle grids of yellow, green, and gray/black blocks and those who do not. No matter which category you fall in, there's a Wordle-inspired game that's perfect for you.
There are many things your iPhone or iPad can do, and Apple does an excellent job of documenting everything on its website. But there are some features that won't show up in any Apple manuals or help pages.
While our smartphones are many things, one of their primary functions is to make calls. Many of us try to avoid ever having to make calls, but there are situations when it's a must, such as wishing your grandma happy Birthday or calling 911 — and in those times you want stellar call quality.
After a long hiatus, we shall once again emerge from the shadowy depths of the internet to build an exploit. This time, we'll be looking at how to defeat a non-executable stack by using the ret2libc technique — a lean, mean, and brilliant way of exploiting a stack overflow vulnerability.
Things just got a lot better in your iPhone's Messages app, and the most significant change lets you text Android users with iMessage-like features such as typing indicators, read receipts, large file sharing, high-quality photos and videos, and even emoji reactions.
You may think your iPhone has all the features you could ever need or want, but that may change once you discover the features and services you're missing out on by residing in the United States.
When you enable Low Power Mode on your iPhone, it's not always clear what measures it's taking to reduce battery drain and conserve power. Changes to energy-hungry features you use daily may be immediately noticeable, but some things you frequently use may be disabled or reduced without any apparent indicators.
There is no iPad version of Apple's Calculator app (at least, not yet), so you won't find it on your Home Screen, in your App Library, or as a shortcut in the Control Center. But that doesn't mean your iPad doesn't have an official calculator.
Automatic phone menus are the worst. You call the number, listen to prerecorded prompts, press button, listen, press button, listen, press button, listen, until you're routed or connected to the right extension, directory, menu, person, or whatever. But you can bypass these automated attendants to get right to where you need to go by setting up a simple shortcut on your iPhone.
