Network enumeration is one of the essential phases of an attack, but it can take a lot of time and effort depending on the size. We've all been spoiled by Nmap and similar tools, and while there is a learning curve involved, they are extremely useful. But there's also GoScan, a tool that builds upon Nmap, offering an automated way to enumerate networks and services quickly.
When it comes to cybersecurity, one layer isn't enough. A complex password (or one created with a password manager) does a good job of protecting your data, but it can still be cracked. Two-factor authentication strengthens this by adding a second layer of security, giving you even more protection against online threats.
While hackers know and love the Raspberry Pi, many don't know of its cheaper cousin, the microcontroller. Unlike a Pi, which can be used more or less like a regular computer, microcontrollers like the Wi-Fi connected ESP8266 require some necessary programming skill to master. In this guide, we'll build an Arduino program from scratch and explain the code structure in a way anyone can understand.
When setting up a Raspberry Pi, it's easy to overlook changing the default password. Like many IoT devices, the Raspberry Pi's default Raspbian operating system installs with a widely-known default password, leaving the device vulnerable to remote access. Using a tool called rpi-hunter, hackers can discover, access, and drop custom payloads on any weak Pi connected to the same network.
You've protected your Ubuntu system from physical attacks, annoyed network hackers, and sandboxed potentially malicious applications. Great! Now, the next logical steps to locking down your OS include thoroughly auditing Ubuntu for weak points, using antivirus software that respects your privacy, and monitoring system logs like a boss.
Once you've installed Ubuntu with security in mind and reduced the possibility of network attacks on your system, you can start thinking about security on an application level. If a malicious file is opened on your system, will an attacker be able to access every file on the computer? The chances are much slimmer if you put the proper defenses in place.
Defcon is the largest hacker conference with something for everyone, whether it be the talks, parties, villages, or any of the hundreds of events. In this guide, we'll take a holistic view at everything that goes into attending the con for the first time, from securing your electronics and making the most of your time to the logistics of getting there and finding the right place to stay.
Contrary to popular belief, augmented reality apps have been available for a while now. I remember using the Layar app (still available for iOS and Android) to explore nearby businesses and landmarks with varying success via an early-generation Android handset.
The Play Store hasn't been the most secure place for apps lately. A quick Google search for "Play Store malware" will give you a taste of some of the malicious apps that snuck their way onto Android's official app store. Google is aware of the problem and they're tying to fix it, but their new Play Protect program doesn't have a great track record, so you might want to look elsewhere.
The year was 1947. Scientists had isolated a virus from a pyrexial rhesus monkey in Uganda and named it after the forest where the monkey lived — Zika.
Step 1: What Exploit Development Is and Why Should I Be Interested on About This Topic
It always looks different when it's not about you. The Internet is our world's Alterego. Those many bits don't really make sense unless we want them to be valuable, to mean something.
First of all, I would like you all to meet my good friend Iggy. There he is, in all his scaly reptilian glory. As you can see, he spends a lot more time on top of his cage than inside of it. You see, Iggy here doesn't deal well AT ALL with confinement. I don't know if it's possible for a lizard to be claustrophobic, but if it is possible, then Iggy definitely is. When his previous owner gave him to me, I tried to keep him in the cage, but I quickly realized that it was a bad idea. When confin...
Your iPhone is fairly secure by default, but Apple's Lockdown Mode takes it to Fort Knox levels of protection. If you're a high-value target for spyware, phishing attempts, and other sophisticated cyberattacks, it's an essential feature. But for almost everyone else, it's an extreme move. If you simply want to verify someone's identity when chatting, Contact Key Verification is a more practical option.
The last iOS software update was a modest one, but iOS 17.4 has a lot more for your iPhone, including changes to emoji, Podcasts, security, Safari, widgets, Apple Cash, CarPlay, and more.
Gaming just got easier, thanks to Apple. A secret feature on your iPhone or iPad makes it so much easier to beat that level or opponent you can't seem to defeat, and it can even help you learn to play a new game faster.
When the topic of Pokémon Go comes up, the typical response is, "Do people still play it?" The answer is a resounding yes!
One UI has an exciting privacy feature that lets you lock apps, photos, videos, and files on your Galaxy device behind Samsung's defense-grade Knox security platform. Only you can unlock it using a pattern, PIN, or passcode, or with biometrics like fingerprint and iris locks. It's like having a safe built right into your smartphone, and it couldn't be easier to set up.
Most websites and apps support two-factor authentication (2FA), which adds an extra layer of security to your accounts by requesting another form of identification beyond username and password. The second factor can be a recovery code, physical security key, or one-time password (OTP) that only you can access, even if someone else has your password. This process is easier than ever thanks to iOS 15.
If you're getting into automation, Bash scripting is usually the way to go. However, there are a couple of limitations, and one of them is logging into another device like a Raspberry Pi and running a script automatically. To help in those situations, we're going to automate delivering an SSH payload with an "expect" script.
With just two microcontrollers soldered together, you can inject keystrokes into a computer from a smartphone. After building and programming the device, you plug it into a desktop or laptop, access it over a smartphone, and inject keystrokes as you would with a USB Rubber Ducky.
Withstanding an attack from a motivated hacker is one of the most important responsibilities a system administrator must undertake. This is especially true for websites that may contain sensitive customer information and a high volume of users. So it's important for a sysadmin to take proactive measures to find and fix vulnerabilities in their websites.
As we've seen with other tools and utilities, administrators typically use certain things to do their job more efficiently, and those things are often abused by attackers for exploitation. After all, hacking is just the process of getting a computer to do things in unexpected ways. Today, we will be covering various methods to perform banner grabbing to learn more about the target system.
GTFOBins and LOLBAS are projects with the goal of documenting native binaries that can be abused and exploited by attackers on Unix and Windows systems, respectfully. These binaries are often used for "living off the land" techniques during post-exploitation. In this tutorial, we will be exploring gtfo, a tool used to search these projects for abusable binaries right from the command line.
In the tech world, our data is always under attack. When you download and install a new app, it can be difficult to know what information the app is actually accessing. Thankfully, a new emphasis on privacy in iOS 14 changes the game, exposing more of what your apps want access to — and even changing some behavior along the way.
Microsoft's built-in antimalware solution does its best to prevent common attacks. Unfortunately for Windows 10 users, evading detection requires almost no effort at all. An attacker armed with this knowledge will easily bypass security software using any number of tools.
The art of fuzzing is a vital skill for any penetration tester or hacker to possess. The faster you fuzz, and the more efficiently you are at doing it, the closer you come to achieving your goal, whether that means finding a valid bug or discovering an initial attack vector. A tool called ffuf comes in handy to help speed things along and fuzz for parameters, directors, and more.
If you've spotted an unintended Ethernet connection and wondered what you could do with all of the information coursing through those wires, there's an easy way to hack into it and find out.
If there's an iOS app you want to hide from your iPhone's home screen, there are a few built-in ways to do so in iOS 14, but there is a clever workaround you can use in older iOS versions. Plus, it also works in iOS 14 as a way to disguise app icons instead of just hiding them, so no app is what it seems.
Automation has been a buzz word for quite some time now, but the principles behind it are as strong as ever. For a hacker or pentester, Bash scripting is one form of automation that cannot be ignored. Virtually any command that can be run from the terminal can be scripted — and should be, in many cases — to save valuable time and effort. And a Bash script just happens to be great for recon.
The internet has undoubtedly changed the way we work and communicate. With technological advances, more and more people can collaborate on the web from anywhere in the world. But this remote-friendly environment inherently brings security risks, and hackers are always finding ways to exploit systems for other uses.
Sudo is a necessity on most Linux systems, most of which are probably being used as web servers. While the principle of least privilege is typically applied, sudo misconfigurations can easily lead to privilege escalation if not properly mediated. Which brings us to SUDO_KILLER, a tool used to identify sudo misconfigurations that can aid in privilege escalation.
If we were to assign a theme for the 2019 edition of the Next Reality 30 (NR30), it might be something along the lines of, "What have you done for me lately?"
|Choose Your View: Quick Bullet Points | Detailed Descriptions Android's newest major update is a special one — it's the tenth full version of the world's most commonly used operating system. The latest release, dubbed simply Android 10 (codename Android Q), was first showcased as a beta back in March 2019, so we've been digging around in it for several months. There's one dramatic visual change, plus there are a lot of goodies in general.
The wait wasn't so long this time. Apple released public beta 3 for iOS 13 on Thursday, July 18, just one day after the release of developer beta 4. For context, Apple took five days to seed public beta 2 after releasing dev beta 3, so it's a pleasant surprise that the latest public beta dropped so soon.
We're pumped for iOS 13 and all of the fresh features and changes that come with it. Developer beta 3 came with new features in the double digits, including AR eye contact in FaceTime and mouse cursor size customization. Developer beta 4, released today, has a few more additions and changes as well.
Rooting. As an Android user, I'm sure you've heard the word once or twice. According to Kaspersky, 7.6% of all Android users root — but for the 92.4% who don't, we wanted to talk to you.
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.
OpenBSD implements security in its development in a way that no other operating system on the planet does. Learning to use the Unix-like operating system can help a hacker understand secure development, create better servers, and improve their understanding of the BSD operating system. Using VirtualBox, the OS can be installed within a host to create a full-featured test environment.
In the aftermath of the unindicted police killings of Michael Brown and Eric Garner, we've been told that the system worked as intended. When our legal system's outcome is at conflict with what a majority of Americans believe is just, it's clear that some changes are needed. But what specifically needs to change? And what can an average citizen with a moral and just cause do to prevent these kinds of tragedies from repeating themselves again and again?
