Frame labels are titles associated with certain segments of content (such as playing a tutorial in sequence and assigning each clip a separate frame label). This tutorial shows you how to set up a custom navigation system for your frame labels, so users can switch back and forth between segments.
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.
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.
Things that are supposed to make life easier for developers and users are often easy targets for exploitation by hackers. Like many situations in the tech world, there is usually a trade-off between convenience and security. One such trade-off is found in a system known as Distributed Ruby, which can be compromised easily with Metasploit.
After gaining access to a root account, the next order of business is using that power to do something more significant. If the user passwords on the system can be obtained and cracked, an attacker can use them to pivot to other machines if the login is the same across systems. There are two tried-and-true password cracking tools that can accomplish this: John the Ripper and Hashcat.
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.
A massive leak appeared the web today, and it's got some huge security implications for every iPhone on the market. On the plus side, it also has some potential for enabling deep-level modifications and jailbreak tweaks.

Any hacker worth her salt will need to debug from time to time. One particularly efficient way to check your code is with the RATS code checking tool. In this video, you'll learn how to use the RATS code checking tool for C/C++, PHP and Perl. For a detailed walkthrough on how to use RATS scanner to audit your source code, take a look!
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.
For many, the stock version of Android is often considered the epitome of what the operating system should look and feel like by default. It's clean and clear of unwanted extra apps that come pre-installed with the system, provides a fluid and fast user experience, and runs on just about any device that has an unlocked bootloader to install a custom ROM with the stock version ready to go.
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.
If you want to embed a video on your website and customize the player so it doesn't look like crap, you've come to the right place:

The modern car is a complicated beast, but fortunately the engine code system makes figuring out what's wrong with a complex vehicle simpler. In this video you'll learn how to use a simple scanner to scan your car and figure out what has made the check engine light come on.
Samba can be configured to allow any user with write access the ability to create a link to the root filesystem. Once an attacker has this level of access, it's only a matter of time before the system gets owned. Although this configuration isn't that common in the wild, it does happen, and Metasploit has a module to easily exploit this security flaw.
Having an efficient workflow is an integral part of any craft, but it's especially important when it comes to probing apps for vulnerabilities. While Metasploit is considered the de facto standard when it comes to exploitation, it also contains modules for other activities, such as scanning. Case in point, WMAP, a web application scanner available for use from within the Metasploit framework.
Like Costco's price codes or the tags on your bread, the numerical codes printed on those sticky little fruit and vegetable labels can reveal a lot of information to us consumers. Once you understand the codes, you can look at that little label (also known as PLU, or "price look up" label) and know whether the produce you're about to buy or eat was treated with pesticides, genetically modified, both, or neither. Before we go any further with deciphering the codes on these labels, let's take a...

There are many password-cracking tools out there, but one of the mainstays has always been John the Ripper. It's a powerful piece of software that can be configured and used in many different ways. Metasploit actually contains a little-known module version of JTR that can be used to quickly crack weak passwords, so let's explore it in an attempt to save precious time and effort.
Websites are often misconfigured in ways that allow an attacker to view directories that are not ordinarily meant to be seen. These directories can contain sensitive information such as private credentials or configuration files that can be used to devise an attack against the server. With a tool called Websploit, hackers can scan targets for these hidden directories without difficulty.

Hacking web applications can sometimes be challenging due to the sheer amount of moving parts they possess. At the core of these apps are HTTP requests and parameters, but these things are often concealed from the user, due to security reasons, convenience, or both. However, a tool called Arjun can be used to discover hidden HTTP parameters in web apps.
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.
Popping a shell is often the main goal of a hacker, and it can be exciting when executed properly, but sometimes they do have their limitations. Metasploit's Meterpreter probably needs no introduction, but this powerful, dynamic payload can offer a leg up over normal shells. To prove it, we'll show how to take a normal command shell and elevate it to a Meterpreter session.
Don't think because your MacBook is using FileVault disk encryption your device is secure or immune to hackers. Here's how to find out if that FileVault password is strong enough to withstand an attack from a motivated attacker.
It is often said that the best hackers remain unknown, and the greatest attacks are left undiscovered, but it's hard for an up-and-coming penetration tester or white hat to learn anything unless one of those factors is actually known or discovered. But the end goal here in our SQL injection lessons is to make that statement as true as possible for us when performing our hacks.
