If the interconnected worlds of blockchain, Bitcoin, and cryptocurrencies scare you a bit, you're not alone. Thanks in part to the extreme and seemingly random fluctuations in the value of Bitcoin over the past three years, more than a few developers and investors are wary of the cryptocurrency revolution and its ties to blockchain development.
The final stage of exploitation is covering your tracks, which involves wiping all activity and logs so the attacker can avoid being detected. It's especially crucial for persistence if the target is going to be accessed again in the future.
There are countless ways in which you can turn your love of tech and coding into a full-fledged career — from developing apps and websites as a freelancer to working in the IT departments of small startups or major tech companies. But one of the best ways that you can put your programming skills to good use is to join the increasingly important world of cybersecurity.
We know our Null Byte readers would like to see some iPhone-hacking scenarios on the site soon, but until we get some of those up, we understand that some of you actually use an iPhone as your primary phone. If that's you, and you would like an easier way to get information from point A (your iPhone) to point B (your computer) and vice versa, there's an all-in-one tool that can help.
Ever a hacker can have their own business that goes beyond cashing in on profitable bug bounties. With the right skill set and certifications, an ethical hacker could build a cybersecurity firm, become a penetration testing for hire, or even just consult on preventive measures to defend against black hats. But learning how to start and grow a business is rarely easy.
Whether you miss the good old days of Telnet or you want to know what hacking was like when security was nothing but an afterthought, Telehack is the game for you. The text-based hacking game is a simulation of a stylized combination of ARPANET and Usenet, circa 1985 to 1990, with a full multi-user universe and player interactions, including 26,600 hosts.
If you're reading this, you're likely a tech-savvy coding pro whose analytical talents are mostly applied to designing apps, cracking passwords, and infiltrating networks — all of which are admirable activities for both aspiring and seasoned white hat hackers. But there are other profitable ways that you can put these types of skills to use, namely in the world of investment and trading.
Whether you're coding a simple app, trying to learn a new programming language, or building an entirely new operating system from scratch, being able to quickly and clearly organize your thoughts is absolutely paramount — even as an ethical hacker or penetration tester.
Kali Linux has come a long way since its BackTrack days, and it's still widely considered the ultimate Linux distribution for penetration testing. The system has undergone quite the transformation since its old days and includes an updated look, improved performance, and some significant changes to how it's used.
Null Byte readers are no strangers to the powers and benefits that come from learning how to code. By knowing only a handful of programming languages and platforms, an intrepid developer can create everything from best-selling apps to spyware in the comfort of his or her own home.
We've already highlighted the importance of learning Microsoft Excel from a hacker's standpoint, but it's also just a good skill to have as you'll likely come across the number-crunching powerhouse at school and work, as well as in other areas of your life, such as budgeting.
No website, service, or platform is immune to being abused or exploited by hackers, and Google Analytics is no exception. To better understand how Google Analytics can help deliver payloads and bypass security protocols, one might want to learn how to use Google Analytics from a user's perspective first.
The overarching and expanding field of data science and analysis has become virtually inseparable from areas such as programming and development.
It's nearly impossible not to be at least somewhat familiar with Microsoft Excel. While it's needed for many office jobs and data analysis fields, hackers could also benefit from improving their spreadsheet skills. Many white hats already know some of the essential Excel hacks, such as cracking password-protected spreadsheets, but there's so much more to know from an attack standpoint.
Few things are more important than being well-versed in data analytics and interpretation when it comes to succeeding in today's increasingly data-driven world. As a data scientist, these skills are the key to a high-paying career. For hackers, there's no better way to defeat the enemy than to become the enemy.
Whether you're looking to add a substantial coding foundation to your hacking skill set or want to get a job in programming and development, knowing one or two programming languages just isn't going to cut it.
A stager is a small piece of software that's typically used by malware to hide what's happening in the early stages of infection and to download a larger payload later.
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.
We've shared a capture-the-flag game for grabbing handshakes and cracking passwords for Wi-Fi, and there are some upcoming CTF games we plan on sharing for other Wi-Fi hacks and even a dead-drop game. While security-minded activities and war games are excellent ways to improve your hacking skills, coding a real video game is also an excellent exercise for improving your programming abilities.
How To: Learn the Ins & Outs, Infrastructure & Vulnerabilities of Amazon's AWS Cloud Computing Platform
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.
Last week, I updated VirtualBox on my computer since I had skipped a few versions, then I could no longer copy text or paste text from my Kali virtual machine to my host OS and vice versa. Installing the Guest Additions didn't seem to do anything, and the bidirectional shared clipboard was enabled, but there was one thing that did work for me that may help you out too if you experience the issue.
Choosing which programming language to learn next can be a truly daunting task. That's the case regardless of whether you're a Null Byter just beginning a career in development and cybersecurity or you're a seasoned ethical hacking and penetration tester with years of extensive coding experience under your belt. On that note, we recommend Python for anyone who hasn't mastered it yet.
We're living in uncertain times. The sudden outbreak of the novel coronavirus and subsequent self-isolation of roughly half the world's population has led to a massive reorganization of the economy, countless layoffs, compromised security networks, and a variety of other significant disruptions that will forever alter the landscape of our daily lives.
With the Wigle WiFi app running on an Android phone, a hacker can discover and map any nearby network, including those created by printers and other insecure devices. The default tools to analyze the resulting data can fall short of what a hacker needs, but by importing wardriving data into Jupyter Notebook, we can map all Wi-Fi devices we encounter and slice through the data with ease.
If you've tossed around the idea of turning your interest in white hat hacking into a career in cybersecurity or IT, now's as good as time as ever to invest some time and energy into improving your skill set.
The Digispark is a low-cost USB development board that's programmable in Arduino and capable of posing as a keyboard, allowing it to deliver a number of payloads. For only a few dollars, we can use the Digispark to deliver a payload to a macOS computer that will track the Mac every 60 seconds, even bypassing security like a VPN.
Anyone who has used Linux long enough is familiar with sudo. Short for superuser do (or substitute user do, depending on who you ask), it allows users to run commands as either root or another user on the system. From a hacker's point of view, sudo is often all that stands between them and root access. We'll be exploring an older vulnerability in sudo that allows a user to run commands as root.
A macOS computer can reveal a lot of information about the owner, including which Wi-Fi network they have permission to access. With an Arduino-based attack, we'll use a five-dollar setup to inject a rogue Wi-Fi network and steal the list of trusted Wi-Fi networks, allowing us to see where the computer has been.
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.
SSH, or the secure shell, is a way of controlling a computer remotely from a command-line interface. While the information exchanged in the SSH session is encrypted, it's easy to spy on an SSH session if you have access to the computer that's being logged in to. Using a tool called SSHPry, we can spy on and inject commands into the SSH sessions of any other user logged in to on the same machine.
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.
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.
Privilege escalation is one of the essential skills a hacker can have and often separates the newbies from the pros. With a continually changing landscape and a plethora of exploits out there, it can be a problematic aspect of any attack. Luckily, some tools can help expedite the process. Linux Exploit Suggester is just one of many to help you get root.
If left unattended, a hacker with a USB Rubber Ducky and physical access to the computer can infiltrate even the most secure computer. Such attacks often go undetected without the use of a tool like USBRip, which can provide you with assurance that your device hasn't been compromised.
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.
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.
Arduino is a language that's easy to learn and supported on many incredibly low-cost devices, two of which are the $2 Digispark and a $3 ESP8266-based board. We can program these devices in Arduino to hijack the Wi-Fi data connection of any unlocked macOS computer in seconds, and we can even have it send data from the target device to our low-cost evil access point.
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.
A lot of time can be wasted performing trivial tasks over and over again, and it's especially true when it comes to hacking and penetration testing. Trying different shells to own a target, and testing out privilege escalation commands afterward, can eat up a lot of time. Fortunately, there is a tool called One-Lin3r that can quickly generate shells, privesc commands, and more.
So you want to know what that person who is always on their phone is up to? If you're on the same Wi-Fi network, it's as simple as opening Wireshark and configuring a few settings. We'll use the tool to decrypt WPA2 network traffic so we can spy on which applications a phone is running in real time.
