You may not have thought of dorks as powerful, but with the right dorks, you can hack devices just by Googling the password to log in. Because Google is fantastic at indexing everything connected to the internet, it's possible to find files that are exposed accidentally and contain critical information for anyone to see.
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.
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.
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.
In the world of technology, there's often a trade-off between convenience and security. The Java Remote Method Invocation is a system where that trade-off is all too real. The ability for a program written in Java to communicate with another program remotely can greatly extend the usability of an app, but it can also open up critical vulnerabilities that allow it to be compromised by an attacker.
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.
With all the web applications out on the internet today, and especially the ones built and configured by novices, it's easy to find vulnerabilities. Some are more perilous than others, but the consequences of even the slightest breach can be tremendous in the hands of a skilled hacker. Directory traversal is a relatively simple attack but can be used to expose sensitive information on a server.
The microphone in a Windows computer is accessible to most applications running on the device at all times and completely without security limitations. Information gathered from recorded audio conversations taking place in the surrounding area of a compromised computer can be used for social engineering, blackmail, or any number of other reasons.
This guide is written for anyone who is practicing his penetration skills using the Metasploitable 2. The problem that we are facing here is that we have to penetrate to Metasploitable 2 and when this happens we understand that we are not logged in as root but as a user with less privileges!
WPA Enterprise is widely used in large corporations as it offers individual and centralized control through a server that authenticate the users (RADIUS server). In this tutorial I will show you how to break the barrier and obtain the user credentials.
Welcome back, my hacker novitiates! As you know by now, the Metasploit Framework is one of my favorite hacking tools. It is capable of embedding code into a remote system and controlling it, scanning systems for recon, and fuzzing systems to find buffer overflows. Plus, all of this can be integrated into Rapid7's excellent vulnerability scanner Nexpose.
Welcome back, my rookie hackers! Most often, the professional hacker is seeking protected information from the target system or network. This might be credit card numbers, personally identifiable information, or intellectual property (formulas, plans, blueprints, designs, etc.). Most of my Null Byte guides have been focused on getting into the system, but this only begs the question—"what do I do when I get there?"
Welcome back, my fledgling hackers! A short while ago, I did a tutorial on conducting passive OS fingerprinting with p0f. As you remember, p0f is different from other operating system fingerprinting tools as it does not send any packets to the target, instead it simply takes packets off the wire and examines them to determine the operating system that sent them.
In my first few articles, we focused on operating system hacks. These hacks have been primarily on older operating systems such as Windows XP, Windows Vista, and Windows Server 2003.
HipHop for PHP is a source code transformer that allows you to optimize your PHP code easily, which will allow you website to run faster on less server space.

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.
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.
There's a lot of misinformation about VPN services, and it stems from the fact that not all of them are created equal. Some focus on privacy, others on security, and a few VPNs are seemingly even purpose-built for the polar opposite: data collection. We made this guide to help clear the air on some of these issues while objectively ranking the best of the best.
Gmail conversations, Facebook private messages, and personal photos can all be viewed by a hacker who has backdoor access to a target's Mac. By livestreaming the desktop or exfiltrating screenshots, this information can be used for blackmail and targeted social engineering attacks to further compromise the mark.
One of the most critical bugs to come out in the last five years was Shellshock, a vulnerability which allows attackers to execute arbitrary code via the Unix Bash shell remotely. This vulnerability has been around for a while now, but due to the ubiquity of Unix machines connected to the web, Shellshock is still a very real threat, especially for unpatched systems.
While there are a variety of privacy-focused search engines available like StartPage and DuckDuckGo, nothing can offer the complete trust offered by creating one's own search engine. For complete trust and security, Searx can be used as free metasearch engine which can be hosted locally and index results from over 70 different search engines.
Dr. Michael Pound, a computer science researcher and professor at the University of Nottingham, uses hashcat and 4 GPUs in parallel to go through 1o billion hashes a second in this Computerphile video. He calls his deep-learning server the "Beast." If you're new to cracking passwords, he does a great job breaking down the process of what's going on as hashcat does its magic.
Hello everybody. I'm back with Part-2 of this series. In this part we will be programming in C our server and i will be explaining one more "key concept" so everybody got a better understanding on this.
I am very new to Null Byte but I find much of its content and community incredibly interesting. I spent quite a bit of time just chronologically going through the posts and I noticed a common theme in many of the beginner posts. Many people seem to want to know the 'secret' or a paragraph on "How to Hack" and become a hacker in a few minutes. I started off this post as a reply to a question from a beginner but thought it might be beneficial to have for those stumbling across this site.
