As protests surge in the wake of George Floyd's murder by a Minneapolis police officer, powerful photographs and videos from the demonstrations have gripped the world, putting our nation's very real and very justifiable widespread civil unrest out into the digital world. Unfortunately, these pictures could put you or others in danger if precautions aren't taken before uploading them online.
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
In iOS 13.5 and later, developers can create and release contact tracing apps for iPhone, which could help slow the spread of the novel coronavirus in the U.S. With these apps comes COVID-19 exposure notifications, which you may or may not want to receive. If you don't want to get these alerts, you can disable them.
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.
When it comes to sniffing Wi-Fi, Wireshark is cross-platform and capable of capturing vast amounts of data. Making sense of that data is another task entirely. That's where Jupyter Notebook comes in. It can help analyze Wi-Fi packets and determine which networks a particular phone has connected to before, giving us insight into the identity of the owner.
So far, iOS 13's major point updates have all been pretty exciting for iPhone. We've seen iOS 13.1, 13.2, and 13.3 come and go, offering more than 60 new features and changes combined to that very first version of iOS 13. While iOS 13.3.1 was a minor update, its successor, iOS 13.4, is a return to form.
Apple's iOS 13 has been available for beta testing since June, and the stable release pushed out to everyone on Thursday, Sept. 19. To help you make the most out of iOS 13 for iPhone, we've rounded up everything you'll want to know, whether a colossal feature, small settings change, interface update, or hidden improvement.
Phone specs get better and better each year, and multiplayer mobile games are right there with them. Instead of playing solo, jump into some real-time gameplay with co-op and player vs. player modes, and battle friends, family, and strangers from around the world. But which multiplayer games are worth your time on Android or iOS?
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.
Smartphone videos get better and better each year. Seven or eight years ago, who would have thought iPhone and Android phones could support 4K video recording. Some phones can even shoot slow-motion at 960 fps. But no matter the resolution or frame rate, a phone's rolling shutter can make quick movements in front of the camera appear wobbly, distorted, or with artifacts.
You may not know it, but the IPv4 address of your computer contains tons of useful information about whatever Wi-Fi network you're on. By knowing what your IPv4 address and subnet mask are telling you, you can easily scan the whole network range, locate the router, and discover other devices on the same network.
There's a lot of misinformation about VPN services, and it stems from the fact that not all of them are created equal. Some focus on privacy, others on security, and a few VPNs are seemingly even purpose-built for the polar opposite: data collection. We made this guide to help clear the air on some of these issues while objectively ranking the best of the best.
Since iCloud's introduction in 2011, you get only 5 GB of complimentary cloud storage with your Apple account. With iPhone backups, app data, iCloud Drive files, and even emails (if you have a Mac, Me, or iCloud email address), you'll quickly run out of space to back up photos and videos. Fortunately, Google offers 15 GB of free storage, making it easy to upload your Camera Roll for safekeeping.
The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.
MoviePass was once the best subscription service on the market for getting cheap movie tickets. For the price and the number of films you could see and save money on, it was unbeatable, but recent changes to the service have made it less enticing. While it still works well for some users, others may have to rely on other options. Personally, I'm leaning toward the latter.
Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
It only takes a few commands to manipulate a MacBook's secure HTTPS traffic and pluck login passwords out of the encrypted data. Let's take Facebook and Gmail hacking to the next level by intercepting Safari and Google Chrome web traffic in real time.
With all the controversy around the Pixel 3 XL, the regular-sized Pixel 3 might be the phone of choice for most users. Thanks to the huge boost in screen size, the little brother is now an easier pickup for those who like a bigger screen. And once more, the internals are the same, giving you the same experience as the 3 XL without the display notch.
The newest version of macOS has arrived. While everyone's mind is being blown by Mojave's groundbreaking new Dark Mode, we'll be taking advantage of its insecure file permissions to establish a persistent backdoor with a self-destructing payload that leaves little evidence for forensics.
You know your infant is advanced. Maybe you want to give her or him a head start at learning things like writing code to develop the next big Fortnite game. Or maybe you just want to play Fortnite with your infant. But the American Academy of Pediatrics discourages screen time for kids under than 18 months, with just one exception: video chat.
In a surprising twist of expectation management, Magic Leap managed to not only ship but deliver the Magic Leap One I ordered on Wednesday by 4 p.m. PT on the same day.
Just like cash, bitcoin is used for everything from regular day-to-day business to criminal activities. However, unlike physical cash, the blockchain is permanent and immutable, which means anyone from a teen to the US government can follow every single transaction you make without you even knowing about it. However, there are ways to add layers of anonymity to your bitcoin transactions.
You may have heard of a signal jammer before, which usually refers to a device that blasts out a strong enough radio signal to drown out the reception of nearby devices like cell phones. Purpose-built jammer hardware is outright illegal in many countries. Still, Wi-Fi is vulnerable to several different jamming attacks that can be done with Kali Linux and a wireless network adapter.
Russian cyber disinformation campaigns have many missions, but one of particular interest is using technology to monitor, influence, and disrupt online communications surrounding culturally sensitive topics or protests. The ability to watch these events, and even filter positive or negative tweets to amplify, gives rise to the ability to execute a number of disinformation campaigns.
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.
Wi-Fi tools keep getting more and more accessible to beginners, and the LAZY script is a framework of serious penetration tools that can be explored easily from within it. This powerful and simple tool can be used for everything from installing new add-ons to grabbing a WPA handshake in a matter of seconds. Plus, it's easy to install, set up, and utilize.
Right on the heels of the iOS 11.4.1 beta 3 release, Apple pushed out iOS 12 beta 2 to registered developers on Tuesday, June 19. Public beta testers received the same version, labeled as iOS 12 public beta 1, six days later on Monday, June 25. Last year, the iOS 11 public beta opened up just five days after the release of iOS 11 developer beta 2, so iOS 12 is pretty much right on track in that regard.
Its official: On May 8, T-Mobile finally released the Android Oreo update for the LG V30 and V30+. Now, every major US wireless carrier has pushed the update. For me, this update is a big deal. Not only does Android Oreo bring some new tools and features, but LG has also included a few additions as well.
Google Calendar is a cornerstone of the Google Suite, perhaps second only to Gmail itself. Whereas email is constantly plagued by phishing attacks, as of yet, the calendar is a relatively untapped social engineering attack vector. But it's relatively easy for an attacker to inject a meeting or event into a target's Google Calendar and use it to exploit them.
There has been significant debate over law enforcement's right to access our digital devices in recent years. New tools from Grayshift and Cellebrite are popping up faster than ever to help government agencies, as well as traditional hackers, break into iPhones. If you're concerned, you can take steps right now to beef up your passcode and prevent outsiders from gaining access to your device.
Update: Google's new Pixel models have been released! Check out our full guides on the Pixel 3 and Pixel 3 XL to see all the details, but we'll leave the rumor roundup intact below for posterity.
A powered-off Windows 10 laptop can be compromised in less than three minutes. With just a few keystrokes, it's possible for a hacker to remove all antivirus software, create a backdoor, and capture webcam images and passwords, among other highly sensitive personal data.
Design flaws in many routers can allow hackers to steal Wi-Fi credentials, even if WPA or WPA2 encryption is used with a strong password. While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. To do this, a modern wireless attack framework called Airgeddon is used to find vulnerable networks, and then Bully is used to crack them.
One of Android's most glaring weaknesses is its lack of an iMessage equivalent. That is, of course, until now. There's one app that will allow Android users to experience iMessage on their non-Apple phone, complete with end-to-end encryption, message effects, and group messaging.
The internet is constantly under siege by bots searching for vulnerabilities to attack and exploit. While conventional wisdom is to prevent these attacks, there are ways to deliberately lure hackers into a trap in order to spy on them, study their behavior, and capture samples of malware. In this tutorial, we'll be creating a Cowrie honeypot, an alluring target to attract and trap hackers.
Hackers can be notoriously difficult to buy gifts for, so we've curated a list of the top 20 most popular items Null Byte readers are buying during their ethical-hacking studies. Whether you're buying a gift for a friend or have been dying to share this list with someone shopping for you, we've got you covered with our 2017 selection of hacker holiday gifts — just in time for Christmas.
The dark web is an intimidating place for a newbie hacker, but it's a powerful tool once you've learned to navigate it safely. To help you out with that, this guide will cover some need-to-know information for traversing the dark corners of the internet while keeping your identity and data safe. (Hint: Using Tor is not enough.)
If I told you to follow as many users as you could possibly follow, in order to get more Instagram followers, that may seem counterintuitive, right? If I told you I'm trying to brainwash/annoy you with how many times I could possibly say versions of the word "follow" in an opening sentence, that would seem weird, too.
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.
The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.
