In this video tutorial, Chris Pels will show how to use a control adaptor to provide different renderings for an ASP.NET server control without actually changing the control itself. In this video, an ASP.NET BulletList control will be adapted to display each list item horizontally using div elements instead of the traditional ul elements. First, see how to create a class that inherits WebControlAdaptor and then implements the code to render the new list format. Next, learn how to map the new ...
While sliding doors is far from a new concept and will be obsoleted once we see wider support for multiple backgrounds (CSS3), it is still a good one for your bag-of-tricks. The theory is that if we have an extra hook in our markup, we can apply two overlapping background images to a single spot of text. When that text grows or shrinks, these overlapping images and reveal more of themselves creating the illusion it is a single expandable graphic. In this video screencast, we do a quickly exam...

There are many considerations to make when choosing a web hosting plan. Storage space, performance, security, and reliability all matter. The cheapest option isn't always the best idea.
People use browsers for all types of things, and in general, we trust a lot of personal information to them. That's why browsers are a perfect attack surface for a hacker, because the target may not even know they are infected and feed you all of the information you could want.

Canary tokens are customizable tracking links useful for learning about who is clicking on a link and where it's being shared. Thanks to the way many apps fetch a URL preview for links shared in private chats, canary tokens can even phone home when someone checks a private chat without clicking the link. Canary tokens come in several useful types and can be used even through URL shorteners.
One of the ultimate goals in hacking is the ability to obtain shells in order to run system commands and own a target or network. SQL injection is typically only associated with databases and their data, but it can actually be used as a vector to gain a command shell. As a lesson, we'll be exploiting a simple SQL injection flaw to execute commands and ultimately get a reverse shell on the server.
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.

It's no secret that Android has a messaging problem. iPhone users can turn to iMessage as a one-stop shop for all their messaging needs — features like read receipts and the ability to text from a computer have been standard with Apple products for quite some time.

Passwords stored in web browsers like Google Chrome and Mozilla Firefox are a gold mine for hackers.

The Watch Dogs video game series came out in 2014, enamoring audiences with the idea of a seemingly magical smartphone that could change traffic signals, hack web cameras, and even remotely control forklifts.
