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.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
Apple's next big developer event happened on June 4, and it was the first glimpse of iOS 12 that anyone's seen. While there were lots of rumored features to be unveiled at WWDC 2018, Apple concentrated mostly on squashing bugs and making iOS work as seamless as it did years ago. Still, we had hoped that Apple would have added these features in iOS 12, but only a few made the cut.
The easiest way around a security policy is to find users who don't follow it. The Have I Been Pwned database identifies accounts with information breached by major third parties like Yahoo and LinkedIn. With Maltego, hackers can locate breached accounts created using company email addresses, potentially giving attackers access to a company account if the employee reuses a compromised password.
While our time with the Protostar VM from Exploit Exercises was lovely, we must move on to bigger things and harder challenges. Exploit Exercises' Fusion VM offers some more challenging binary exploitation levels for us to tackle. The biggest change is that these levels are all network services, which means we'll write our first remote exploits.
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.
After finding and monitoring nearby wireless access points and devices connected to them, hackers can use this information to bypass some types of security, like the kind used for Wi-Fi hotspots in coffee shops, hotels, and in flights high above the ground. By swapping their MAC address for that of someone already connected, a hacker can bypass the MAC filter and connect freely.
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.
Even though most phones don't have Oreo yet, Google has released Android 9.0 Pie. It's available on Google's own Pixel devices, and updates should soon be available to partnered devices from Essential, Nokia, Oppo, Sony, Vivo, and Xiaomi. We're already digging into it to highlight all of the features and changes.
The headphone jack is becoming outdated technology in smartphones — that's what many manufacturers would have you believe. For the convenience of the audiophiles out there, we recently published our list of all phones that have removed the 3.5 mm jack. But what did each company gain inside their flagship phones by removing this supposedly antiquated port?
The public leaks of NSA tools and information have led to the release of previously secret zero-day exploits such as EternalBlue, which was used in the notorious WannaCry ransomware attack. Despite multiple patches being released, many users have failed to update their systems, so many devices are still vulnerable to these now-public attacks.
The Watch Dogs video game series came out in 2014, enamoring audiences with the idea of a seemingly magical smartphone that could change traffic signals, hack web cameras, and even remotely control forklifts. This may sound like science fiction, but The Sonic uses a customized flavor of Kali Linux to allow you to unleash the power of Kali from any smartphone — all without the need to create a hotspot to control it.
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.)
PowerShell Empire is a post-exploitation framework for computers and servers running Microsoft Windows, Windows Server operating systems, or both. In these tutorials, we will be exploring everything from how to install Powershell Empire to how to snoop around a target's computer without the antivirus software knowing about it. If we are lucky, we might even be able to obtain domain administrator credentials and own the whole network.
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.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
When WhatsApp first came out in 2010, it quickly gained notoriety as a great way to meet new people all over the world thanks to group chats, which allow multiple admins for each group that can all add participants from their own contacts lists.
If maintaining privacy is an ongoing battle, the front line is your smartphone. Apple included several new security features in iOS 10, but at the same time, some of the best new functionality comes with potential privacy trade-offs that everyone needs to understand.
Now that smartphones have ensured that we're connected to the internet 24/7, online privacy has become more important than ever. With data-mining apps hoping to sell your information for targeted ads, and government agencies only one subpoena away from knowing every detail of your private life, encryption has become our last line of defense.
If you're one who enjoys a good DIY project, or if you're just tired of paying exorbitant labor fees to have your vehicle serviced every 5,000 miles, changing your own oil can be a rewarding endeavor. Even though cars and trucks are becoming increasingly over-engineered these days, manufacturers generally see to it that the basic maintenance items can still be taken care of in your driveway with a few common tools.
Apple Pay has been available to use in stores, as well as in select apps and websites, ever since its first appearance in iOS 8.1. Now, with iOS 12, there are currently 13 different iPhone models that support Apple Pay functionality without the use of an Apple Watch, and the list of partnered stores that accept Apple Pay has only grown. Here's our always-up-to-date list to keep you in the know.
While many of the features in the iPhone 16 and 16 Pro series build on what we've seen in previous iPhone models, Apple has packed the 2024 lineup with iOS 18 and plenty of fresh upgrades worth considering.
Taking a cue from Apple and its Health app for iOS, Google has created a central hub to collect health and fitness data on your Android device. With it, you can share and sync health and fitness data, such as steps, heart rate, water intake, sleep quality, and calories burned, between different apps and devices and use your favorite app to view all the information.
TikTok is all the rage right now, and its green screen effect is one of the more popular augmented reality tricks creators use to boost their viewership numbers. Now Snapchat has leveled the playing field by making it easier to access its own green screen effect.
In the dark, even the lowest brightness option on the iPhone can still feel a thousand burning suns. No matter whether you're in bed or at the movie theater, you don't want to create a distraction with your smartphone. That's why you might want a brightness that isn't readily available on your device — but luckily, there may be a way to go lower than the lowest brightness.
Apple wants to support the advertising economy, but its primary focus of late has been user privacy and security. In Safari, cross-site tracking, which lets content providers track you across websites and apps to show you more targeted ads, is disabled by default. However, content providers can get around that using less privacy-invasive ad measurements, but you can stop that too in iOS 14.5.
You may be wondering what exactly makes the Pixel 4a's camera so great. Compared to its predecessor, it has the same Sony IMX363 sensor and no additional hardware. Well, beyond stellar image processing, it also has several great new features that Google has added since they released the Pixel 3a last year.
The Pi-hole project is a popular DNS-level ad blocker, but it can be much more than that. Its DNS-level filtering can also be used as a firewall of sorts to prevent malicious websites from resolving, as well as to keep privacy-killing trackers such as Google Analytics from ever loading in the browser. Let's take a look at setting a Pi-hole up and customizing a blacklist to suit your needs.
Smartphones are inherently bad for privacy. You've basically got a tracking device in your pocket, pinging off cell towers and locking onto GPS satellites. All the while, tracking cookies, advertising IDs, and usage stats follow you around the internet.
The top five apps of the 2010s were all social media apps of some kind, and the fact that's not surprising to you says a lot. We may use them for other reasons here and there, but our phones are social media machines at their cores. The thing is, some make better machines than others.
When it comes to platform games on mobile, endless runners are some of the hardest to play since they can go on seemingly forever. There's always room for improvement since your goal is to beat your previous score (or someone else's high score). But which endless running games are worth your time?
Android's settings menu is actually pretty daunting. There are options for nearly everything, so in the sea of various menus and submenus, it's easy to overlook important privacy and security settings. On Google's Pixel phones in particular, there are 20 such settings that you should double check.
There have been concerns with how much personal information Google tracks and all the things they know about us. Of course, that's what makes Google services so useful, they can use that information to cater to each of us individually. So yes, it serves a purpose, but it's not great for personal data security.
Sharing your personal information can come up for any number of reasons: you may want to get in touch with a colleague after work or you've been involved in a car accident and need to stay in contact with the other driver. Unfortunately, giving out information can be the key for others to find your social media accounts, such as Instagram, whether you want it to happen or not.
It is almost indisputable that smartglasses and head-worn displays are the future of augmented reality. However, at this precise moment, they are still a very niche market.
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.
The gig economy is thriving, and if you aren't already making money with your phone, you could be missing out on easy residual income. Some people just want extra cash, and some even manage to completely ditch the 9–5, enabling them to work at their own pace and set their own hours.
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.
The calendar app is one of the unsung heroes found within your iPhone. It's the ultimate personal assistant that you've come to rely on to keep track of your schedule and ensure you never miss a class or meeting, all while reminding you of upcoming birthdays and deadlines to help maintain good relationships with loved ones and colleagues.
There's always an iPhone in our list of top phones for privacy and security, due in large part to advanced security measures like Face ID, consistent iOS updates, and easy ways to prevent unwanted access and excessive data sharing. However, some of those options actually do the opposite and hinder security. It all depends on how you use your iPhone, but you should at least know everything available.
