Welcome back, my fledgling hackers! One of the first issues any hacker has to address is reconnaissance. Before we even begin to hack, we need to know quite a bit about the target systems. We should know their IP address, what ports are open, what services are running, and what operating system the target is using. Only after gathering this information can we begin to plan our attack. Most hackers spend far more time doing reconnaissance than exploiting.
MAC addresses (not to be confused with Macs) are unique identifiers assigned to network devices in order to access the internet. Hotels use these Mac addresses in order to check if a registered patron has agreed to their terms and conditions, how much bandwidth is being consumed, and of course, whether they've paid or not.
Summer is coming so start saving your popsicle sticks (or more conveniently buy them from a craft store) to make your very own mini American flag. This is a great activity to take into the class room or just to pass the time on a summer’s afternoon.

One aspect of Android's interface that remains clunky is its gesture- or button-based navigation bar, mainly because app developers aren't fully utilizing the tools available to them. But a new feature Google is working on may finally make your nav bar more uniform across your apps.
WhatsApp has a new sticker-making tool in the iPhone app that lets you create custom stickers directly in chats using your own images, eliminating the need to rely on third-party apps to make them.
The enterprise-focused category of augmented reality doesn't often get the headlines due to its relatively sedate profile as a mostly factory floor and training-based tool.
With fears over the COVID-19 pandemic subsiding, live concerts are returning. And Doritos wants to send music fans to a few of them via an augmented reality promotion.
The enterprise applications powering the adoption of the HoloLens 2 are only just ramping up as developers continue to work with the still relatively new hardware.
End-to-end encryption makes WhatsApp chats private and secure. However, if someone has access to your iPhone, they can easily open the app and browse through all of your personal conversations. Luckily, there's an easy way to block any would-be intruders at the gates — just lock the app behind Face ID or Touch ID.
When approaching a target, having a precise and detailed plan of attack is absolutely necessary. One of the main goals is to increase the attack surface since the more opportunities there are for exploitation, the greater the chances of success. Subdomain enumeration is one method used to increase the attack surface, and we'll be using a tool called Subfinder to discover hidden subdomains.
Anyone looking to have a complete set of design tools at their fingertips needs to look no further than Adobe's Creative Cloud. This suite of applications is the go-to platform for creative software and is, in many ways, a must-know in fields like graphic design, video editing, and photography.
If you're an aspiring or even well-established web or app developer, the good news is that there's a virtually limitless number of lucrative opportunities waiting for you, regardless of whether you're looking to work for a company or as a freelancer.
It's a myth that regular users only need the protection of a virtual private network when on a public Wi-Fi connection. First, almost all network connections can be accessed without the proper permissions. Second, ethical hackers also need to think about using a VPN as one step to encrypting and protecting their activity and identity during pentests, phishing, and other actions.
Post-exploitation is often not quite as exciting as popping the initial shell, but it's a crucial phase for gathering data and further privilege escalation. Once a target is compromised, there's a lot of information to find and sift through. Luckily, there are tools available that can make the process easy. One such tool is Postenum.
File permissions can get tricky on Linux and can be a valuable avenue of attack during privilege escalation if things aren't configured correctly. SUID binaries can often be an easy path to root, but sifting through all of the defaults can be a massive waste of time. Luckily, there's a simple script that can sort things out for us.
While we haven't covered Amazon Web Services, or AWS, on Null Byte before, Amazon's cloud computing platform is ripe for attack by hackers, pentesters, and cybersecurity researchers. It's also an excellent cloud hosting service to build or use vulnerable-by-design AWS setups and frameworks.
With stay-at-home orders for most of us in the US because of the new coronavirus, many of you are likely struggling to be productive and efficient when working from home. Unless you've worked from home before, it can be challenging to separate work from personal life throughout the "workday." But your iPhone can help make the transition easier and more successful.
Without admin privileges, installing additional software, or modifying the Windows 10 firewall, an attacker can alter a router and perform a variety of exploits. It's accomplished by forwarding requests from Kali through a backdoored Windows computer to the router gateway with simple SSH tunnels.
Let's be honest, nobody enjoys doing cardio — they tolerate it. That dreadful, loathsome feeling you experience when you're doing cardio workouts isn't unique to you, it's almost universal. Sure, it gets easier the more you do it, but there are some ways to make it better now.
SMB (Server Message Block) is a protocol that allows resources on the same network to share files, browse the network, and print over the network. It was initially used on Windows, but Unix systems can use SMB through Samba. Today, we will be using a tool called Enum4linux to extract information from a target, as well as smbclient to connect to an SMB share and transfer files.
Apple's latest update for iPhones, iOS 13, introduces over 200 new and exciting features. Many of those changes come to Siri, resulting in a better, more useful version of the digital assistant we've known for years. If you simply look at iOS 13's webpage, however, you wouldn't realize just how much Siri has changed this time around. We're here to fill in the blanks.
Action games encompass a wide array of categories, ranging from racing games that pit you against players the world over for track domination, to endless runners that push you to set ever higher scores, and RPGs that let you embark on adventures in fantasy worlds. With such a huge selection of titles to look through, it's all too easy to overlook a game you might otherwise like.
Though not as flashy as other mobile gaming genres like first-person shooters, puzzle games continue to glue players to their phones. Puzzlers are perfect companions while out and about or on a commute, and they're also a great way to stimulate your brain and hand-eye coordination in a fun, relaxing way.
Passwords on Windows are stored as hashes, and sometimes they can be tough to crack. In certain situations, though, we can get around that by using the hash as is, with no need to know the plaintext password. It's especially interesting if we can manage to get the hash of an administrative user since we can then authenticate with higher privileges by performing an attack known as pass the hash.
Phone numbers often contain clues to the owner's identity and can bring up a lot of data during an OSINT investigation. Starting with a phone number, we can search through a large number of online databases with only a few clicks to discover information about a phone number. It can include the carrier, the owner's name and address, and even connected online accounts.
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.
The hugely successful S10 series of flagships may be a tough act to follow, but Samsung has proven that it's up to the task with the Galaxy Note 10. The latest phablet bearing the Note name is the first of its line to come with an even larger variant, and boasts an eye-pleasing design with impressive performance to boot.
Microsoft Office files can be password-protected in order to prevent tampering and ensure data integrity. But password-protected documents from earlier versions of Office are susceptible to having their hashes extracted with a simple program called office2john. Those extracted hashes can then be cracked using John the Ripper and Hashcat.
With a simple social engineering trick, sudo passwords can be captured in seconds without the target's knowledge. The passwords can then be saved to a file or exfiltrated to another computer on the network.
Among the younger generation, Roblox rivals major titles like Minecraft as one of the most popular online games out there. In fact, it's common to hear children tell new playmates to "friend me in Roblox!" so they can play together online. There's nothing inherently sinister here, but with all the online interaction, kids' safety becomes a factor.
With the number of web applications out there today, it comes as no surprise that there are just as many vulnerabilities waiting for hackers to discover. Finding those vulnerabilities can be a difficult task, but there are plenty of tools available to make the process easier. While it won't help find any zero-days, web scanners such as Uniscan will detect common vulnerabilities.
Traditionally, if you were looking for end-to-end encrypted messaging, you'd stick with something like iMessage, WhatsApp, or Signal. However, if you already use Facebook Messenger, you have all you need for truly private chats with its built-in E2E encryption. It's available to all users, on Android and iOS — you just need to know where to look.
If you ask Siri to check the weather on your iPhone right now, you'll get information from the stock Weather app in iOS — even if you have and prefer other weather apps installed. But that doesn't have to be the case. Thanks to Siri Shortcuts in iOS 12 and later, you can set specific phrases that Siri will respond to for any compatible weather app you want.
The OnePlus 6T is easily one of 2018's best value phones for many reasons, especially when it comes to rooting and modding. But like many new phones, it's plagued with the single bottom-firing speaker that left us wanting more in the sound department. The speaker is decent on its own, but it appears to have some hidden potential at the same time.
Cross-site scripting is one of the most common vulnerabilities found on the web today, with repercussions of this type of flaw ranging from harmless defacement to sensitive data exposure. Probing for XSS can be tedious and time-consuming for an attacker, but luckily there are tools available to make things a little easier, including Burp Suite, Wfuzz, and XSStrike.
