For many of you, this is common knowledge. But I still regularly see comments posted here and elsewhere asking, "This <AV bypass> doesn't work, because when I upload my payload to VirusTotal...."
Hi, dear co-apprentices and wise masters. I've been recently trying to learn the basics to hacking here, and I've read all guides on Wi-Fi hacking and noticed no word is dedicated to this awesome script that comes bundled with Kali!
Welcome back, my aspiring hackers! As I mentioned in earlier posts, the best hackers (or at least those not behind bars) have a keen understanding of digital forensics. If I am tasked to intrude upon an enemy's file server to retrieve war plans, such as in this tutorial, it is essential to my country's (and my own) well-being that it not be traced back to me. Understanding digital forensics helps us to leave without a trace and never have a trail back to us or our employer.
What if someone asks you to do a Nmap scan but you left your pc at home? What if a golden opportunity shows during a pentest but you were walking around the building, taking a break?
Welcome back, my greenhorn hackers! My preference for Linux as a hacking platform is well documented, and I have even created a series of tutorials to train new hackers. Without being proficient in Linux, you can't really call yourself a hacker.
Welcome back, my budding hackers! We've spent a lot of time learning to compromise Windows systems, and we've successfully compromised them with Metasploit, cracked their passwords, and hacked their Wi-Fi. However, very little time was spent developing ways to extract the information from the system once inside.
Welcome back, my tenderfoot hackers! So many readers in the Null Byte community have been asking me questions about evading detection and hacking undetected that I decided to start a new series on digital forensics.
Welcome back, my hacker trainees! A number of you have written me regarding which operating system is best for hacking. I'll start by saying that nearly every professional and expert hacker uses Linux or Unix. Although some hacks can be done with Windows and Mac OS, nearly all of the hacking tools are developed specifically for Linux. There are some exceptions, though, including software like Cain and Abel, Havij, Zenmap, and Metasploit that are developed or ported for Windows.
Everyone in these days have so many pressures. Either he or she is a working professional or student and these pressures create tension which can cause stomach disorders. As I myself experience very chaotic routines in my life, I've suffered with stomach disorders for ten years of my life. I have tried each and every type of medicine from allopathic to homeopathic and found no results. I lost hope. By chance I discovered something very simple to cure my troubled stomach and since then I have ...
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.
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.
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.
Attacks against databases have become one of the most popular and lucrative activities for hackers recently. New data breaches seem to be popping up every week, but even with all of that attention, databases continue to be a prime target. All of these attacks have to start somewhere, and we'll be exploring a variety of methods to gather information on PostgreSQL databases with Metasploit.
It's been said time and time again: reconnaissance is perhaps the most critical phase of an attack. It's especially important when preparing an attack against a database since one wrong move can destroy every last bit of data, which usually isn't the desired outcome. Metasploit contains a variety of modules that can be used to enumerate MySQL databases, making it easy to gather valuable information.
Router gateways are responsible for protecting every aspect of a network's configuration. With unfettered access to these privileged configurations, an attacker on a compromised Wi-Fi network can perform a wide variety of advanced attacks.
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.
One of the first steps when pentesting a website should be scanning for hidden directories. It is essential for finding valuable information or potential attack vectors that might otherwise be unseen on the public-facing site. There are many tools out there that will perform the brute-forcing process, but not all are created equally.
UnrealIRCd is an open-source IRC server that has been around since 1999 and is perhaps the most widely used one today. Version 3.2.8.1 was vulnerable to remote code execution due to a backdoor in the software. Today, we will be exploiting the vulnerability with Metasploit, examining the underlying code to understand it, and creating our own version of the exploit in Python.
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.
One of the most common web application vulnerabilities is LFI, which allows unauthorized access to sensitive files on the server. Such a common weakness is often safeguarded against, and low-hanging fruit can be defended quite easily. But there are always creative ways to get around these defenses, and we'll be looking at two methods to beat the system and successfully pull off LFI.
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.
KeePassX, 1Password, and LastPass are effective against keyloggers, phishing, and database breaches, but passwords managers rely on the operating system's clipboard to securely move credentials from the password vault to the web browser. It's within these few seconds that an attacker can dump the clipboard contents and exfiltrate passwords.
UAC is something we've all dealt with on Windows, either as a user, administrator, or attacker. It's a core feature of the Windows security model, and for the most part, it does what it's supposed to. But it can be frustrating as a hacker when attempting privilege escalation, but it's easy enough to bypass UAC and obtain System access with Metasploit.
If you find yourself with a roommate hogging limited data bandwidth with video games or discover a neighbor has invited themselves into your Wi-Fi network, you can easily take back control of your internet access. Evil Limiter does this by letting you control the bit rate of any device on the same network as you, allowing you to slow or even stop data transfer speeds for them completely.
The price of hacking Wi-Fi has fallen dramatically, and low-cost microcontrollers are increasingly being turned into cheap yet powerful hacking tools. One of the most popular is the ESP8266, an Arduino-programmable chip on which the Wi-Fi Deauther project is based. On this inexpensive board, a hacker can create fake networks, clone real ones, or disable all Wi-Fi in an area from a slick web interface.
Information gathering is one of the most important steps in pentesting or hacking, and it can often be more rewarding to run things on the target itself as opposed to just running scripts against it remotely. With an SQL injection, a hacker can compromise a server and, ultimately, upload and run the "unix-privesc-check" script locally in order to further identify possible attack vectors.
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.
The ability to stay organized and be resourceful with data gathered from recon is one of the things that separates the true hackers from the script kiddies. Metasploit contains a built-in database that allows for efficient storage of information and the ability to utilize that information to better understand the target, which ultimately leads to more successful exploitation.
Computers all over the world rely on a program called "libssh" to use the SSH communications protocol, which allows trusted users to log in and administer computers remotely. Due to a flaw in libssh, fooling a computer into granting SSH access is as easy as telling it you already have permission. The vulnerability can lead to an attacker gaining complete control over a device.
Many online users worry about their accounts being breached by some master hacker, but the more likely scenario is falling victim to a bot written to use leaked passwords in data breaches from companies like LinkedIn, MySpace, and Tumblr. For instance, a tool called H8mail can search through over 1 billion leaked credentials to discover passwords that might still be in use today.
The ability to execute system commands via a vulnerable web application makes command injection a fruitful attack vector for any hacker. But while this type of vulnerability is highly prized, it can often take quite a bit of time to probe through an entire application to find these flaws. Luckily, there is a useful tool called Commix that can automate this process for us.
One of the best ways to improve your skills as a hacker is to learn to combine different avenues of attack to achieve success. What if it were possible to get a victim to connect to our machine and execute a chosen payload on our behalf? This is indeed possible with the almighty Metasploit and the aid of a technique known as command injection.
The newest version of macOS has arrived. While everyone's mind is being blown by Mojave's groundbreaking new Dark Mode, we'll be taking advantage of its insecure file permissions to establish a persistent backdoor with a self-destructing payload that leaves little evidence for forensics.
With just one line of Ruby code embedded into a fake PDF, a hacker can remotely control any Mac computer from anywhere in the world. Creating the command is the easy part, but getting the target to open the code is where a hacker will need to get creative.
It's always a good idea to know how an attack works at the very basic level. Manual techniques for exploitation often find holes that even the most sophisticated tool cannot. Sometimes, though, using one of these tools can make things so much easier, especially if one has a solid foundation of how it works. One such tool can help us perform a cross-site request forgery with minimal difficulty.
Using Netcat to backdoor a macOS device has its short-comings. If the compromised Mac goes to sleep, the Netcat background process will occasionally fail to terminate correctly; This leaves Netcat running infinitely in the background and the attacker with no new way into the device. As an alternative, we'll use the lesser-known Tcl shell which can handle abrupt backdoor disconnections.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Hacking Wi-Fi is a lot easier than most people think, but the ways of doing so are clustered around a few common techniques most hackers use. With a few simple actions, the average user can go a long way toward defending against the five most common methods of Wi-Fi hacking, which include password cracking, social engineering, WPS attacks, remote access, and rogue access points.
Once a hacker has created a PowerShell payload to evade antivirus software and set up msfconsole on their attack system, they can then move onto disguising their executable to make it appear as a regular text file. This is how they will get a Windows 10 users to actually open the payload without knowing they are doing so.
