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.
Compromised uTorrent clients can be abused to download a malicious torrent file. The malicious file is designed to embed a persistent backdoor and execute when Windows 10 reboots, granting the attacker remote access to the operating system at will.
Post-exploitation information gathering can be a long and drawn-out process, but it is an essential step when trying to pivot or establish advanced persistence. Every hacker should know how to enumerate a target manually, but sometimes it is worth it to automate the process. Metasploit contains post modules that can quickly gather valuable information about a target, saving both time and effort.
Microsoft.com is one of the most extensive domains on the internet with thousands of registered subdomains. Windows 10 will ping these subdomains hundreds of times an hour, making it challenging to firewall and monitor all of the requests made by the operating system. An attacker can use these subdomains to serve payloads to evade network firewalls.
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.
Reconnaissance is the phase of an attack where a red team or hacker designs a strategy based on the information they can learn about the target, as well as what the available attack surface looks like. These scans can take time to discover relationships, but Raccoon OSINT scanner coordinates multiple automated scans to produce invasively detailed reports on a target with a single command.
Database technology has vastly improved the way we handle vast amounts of data, and almost every modern application utilizes it in one way or another. But the widespread use of databases naturally invites a slew of vulnerabilities and attacks to occur. SQL injection has been around for awhile, and as such, there are many defense methods in place to safeguard against these types of attacks.
Passwords and data stored in web browsers are extremely valuable to hackers. If not for financial gain, black hat hackers may still leak your passwords and personal information for amusement. Never undervalue what you're worth to a hacker.
Google, Amazon, and Facebook are always listening. But what's worse? Hackers are listening, too. Windows PCs are particularly vulnerable, but with a few simple commands, a remote attacker can even take over the microphone on someone's Mac computer, streaming audio and listening to private conversations in real time without the victim's knowledge, abusing an overlooked security consideration.
While hackers have taken advantage of numerous vulnerabilities in Adobe's products to deliver payloads to Windows users via PDF files, a malicious PDF file can also wreak havoc on a Mac that's using the default Preview app. So think twice before double-clicking a PDF open on your MacBook — it might just be a Trojan with a rootkit inside.
For SQL injection, the next step after performing reconnaissance and gathering information about a database is launching an attack. But something seems off .. in the real world, it's usually not quite as simple as passing in a few fragments of SQL code to an input field and seeing all that glorious data displayed right in the browser. This is when more advanced techniques are needed.
The conversation of which operating system is most secure, macOS vs. Windows, is an ongoing debate. Most will say macOS is more secure, but I'd like to weigh in by showing how to backdoor a MacBook in less than two minutes and maintain a persistent shell using tools already built into macOS.
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.
A convincing domain name is critical to the success of any phishing attack. With a single Python script, it's possible to find hundreds of available phishing domains and even identify phishing websites deployed by other hackers for purposes such as stealing user credentials.
In the previous article in this short series, we learned how to find our neighbor's name using publicly accessible information and how to monitor device activity on their home network. With this information at our disposal, it's time to get into installing and configuring the necessary tools to begin our attack on John Smith's computer.
SSH is a powerful tool with more uses than simply logging into a server. This protocol, which stands for Secure Shell, provides X11 forwarding, port forwarding, secure file transfer, and more. Using SSH port forwarding on a compromised host with access to a restricted network can allow an attacker to access hosts within the restricted network or pivot into the network.
Any internet user will need to download files eventually, and most simply have faith that what they are downloading is trustworthy. This doesn't give much clarity into the contents of the file, but if the file's author published the original checksum, comparing it to the SHA-256 hash of the downloaded file can ensure nothing was tampered with.
Besside-ng is the hidden gem of the Aircrack-ng suite of Wi-Fi hacking tools. When run with a wireless network adapter capable of packet injection, Besside-ng can harvest WPA handshakes from any network with an active user — and crack WEP passwords outright. Unlike many tools, it requires no special dependencies and can be run via SSH, making it easy to deploy remotely.
The USB Rubber Ducky comes with two software components, the payload script to be deployed and the firmware which controls how the Ducky behaves and what kind of device it pretends to be. This firmware can be reflashed to allow for custom Ducky behaviors, such as mounting USB mass storage to copy files from any system the Duck is plugged into.
ProtonMail has long been the favorite of journalists and security-conscious professionals, with Edward Snowden the most famous example. But these days, everyone cares about anonymity, so it's no surprise that ProtonMail currently has over 2 million users. And now the service is even better.
Hello, Null Byters. I'm Barrow, and I'm excited to introduce myself as the new admin here on Null Byte. Just like previous admins have done before me, I will be writing new guides, updating older guides if they need it, and responding to some of your issues in the forum. Before I get started with any of that, though, I wanted to talk a little bit about myself and the future of Null Byte.
So, you want to perform an exploit on a victim, but you're not on the same network as their machine. In this tutorial, I'll be showing you how to set up a meterpreter reverse_tcp attack to work over the internet.
Hello aspiring hackers, It's been a while since I wrote a tutorial, so I figured I might just share one of the tools that I have created to help the community grow.
How to do an NMAP scan on Armitage to find IPs within a certain range. Armitage is a gui interface of Metasploit, and advanced hacking/exploiting program. It can be downloaded from http://metasploit.com/ and http://fastandeasyhacking.com/ and you will need NMAP. http://www.nmap.org/
Hello everyone Today I will show a different way to exploit a windows machine with a reverse https payload..."wait...why https? Isn't tcp good anymore?"
In the second part of this tutorial, we are going to crack the hashes that we've captured previously. I'm going to explain how to do it with the powerful John the Ripper. It comes with Kali by default, so no need to install!
Your English teacher is a creep. The way he looks at your girlfriend, the way he always spends ages with the girls in the class going over their work but not the boys, just the way he is.
Though you can use the Social Engineering Toolkit to clone websites, this way is much more customisable.
Welcome back, my novice hackers! This new series on Bluetooth hacking was inspired by a recent episode of Mr. Robot (my favorite TV show). In episode 6, Eliot hacked the bluetooth keyboard of the police office in order to hack the prison and release his nemesis, Vera. This is just one of the many hacks we will explore in the series.
Ruby is a dynamic, general-purpose programming language created by Yukihiro "Matz" Matsumoto in Japan around the mid-90's. It has many uses but with it's flexibility, it makes a great language to write exploits in. In fact, the entire Metasploit Framework is written in Ruby! The sole purpose of this series is to teach hackers the basics of Ruby, along with some more advanced concepts that are important in hacking.
Now that we have control over a victim's browser, we need to use some attacks to maintain the connection, or even better: upload a shell.
Welcome back, my tenderfoot hackers! As you know, DNS, or Domain Name System, is critical to the operation of the Internet. It provides us with the ability to type in domain names such as www.wonderhowto.com rather than the IP address. This simple service saves us from having to memorize thousands of our favorite website IP addresses. Instead, we simply type in a domain name to retrieve the website.
Welcome back, my budding hackers! Recently, I showed you how you could exploit the widely disseminated OpenSSL vulnerability that has to become known as "Heartbleed". Although the world has known about this vulnerability for over a month now, it will likely take many more months—or even years—for everyone to close this vulnerability.
Welcome back, my rookie hackers! The more we know about a system or network, the better our chances of owning it and not leaving a trace for investigators to follow. One of the often overlooked sources for information is the Simple Network Management Protocol (SNMP). Many rookie hackers are not even aware of it, but it can prove to be a treasure trove of information, if you understand how it works and how to hack it.
Welcome back, my budding hackers! One of the most time-consuming, but necessary, activities in hacking is reconnaissance. Before we can hack a system, we need to know what operating system it's running, what ports are open, what services are running, and hopefully, what applications are installed and running.
UPDATE: A patch to fix the exploit has been released. Download it here.
Do you own an HP printer? If so, it may be vulnerable to malware attacks. Researchers at Columbia University discovered that 25% of Hewlett-Packard printers have significant vulnerabilities that put your printer in danger from hackers—even your home. With a budget of just $2,000, researchers Salvatore Stolfo and Ang Cui were able to hack into the printers using remote firmware to install malware, and in some cases even cause the printer to catch on fire. The main issue is with the printer's c...
The macOS 10.14 security update tried to make parts of the operating system difficult for hackers to access. Let's take a closer look at how its new feature works and what we can do to spoof the origin of an application attempting to access protected data.
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.
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.
