The Process Behind Cross-Site Scripting Attacks in the San Jose Area

Software Development

If you manage any type of website or web application, you need to know about cross-site scripting. This term concerns a type of internet-based attack that initiates from a hidden source. The mere visiting of a website that is affected will cause the malicious script to activate. The worst part is that the user will probably not even notice what is going on. Therefore, if you care about your digital assets, you should learn more about cross-site scripting (XSS) attacks.

The Basics of XSS

There are some specific aspects of cross-site scripting that all webmasters and developers in San Jose need to know. First of all, this code is client-side meaning that it initiates on the user’s end. The script will activate inside the web browser screen of a web visitor. All the steps will occur without the user’s consent or awareness.

The infected page or app is merely a means to an end. Once someone visits such a site, the script is injected into the web browser software. From there, it can carry out a number of harmful activities according to its programmed purpose.

What Makes a Site Vulnerable?

Sites that allow for parsing in the browser of the user are often the most vulnerable to attacks. This means that any site that uses ActiveX, Flash or JavaScript can be targeted for injection attempts. Surprisingly, some hackers can even do this through plain, old CSS. In the end, almost an uncountable number of sites can be in jeopardy.

The Types of Attacks

There is a lot a hacker can do with XSS. Even though JavaScript is subject to the control mechanisms of any given browser, it can still be exploited. Modern versions of JavaScript can access APIs in HTML5. Therefore, an attacker can get access to a user’s personal information, such as a location, webcam footage and even the files on a hard drive. It is even possible to view a user’s cookies to impersonate them on social media sites or financial websites. Unfortunately, the list goes on and on.

Getting the Right Kind of Help

Luckily, there are some steps you can take to help eliminate the possibility of XSS attacks. You can begin by making sure that all client-side input is properly sanitized. All forms of input should be checked for injections within the application itself. Doing this will help stop attacks in San Jose, CA.
