What is Reflected XSS? What are Javascript Events and How do They Impact XSS Vulnerability? Exploiting XSS: How Can User Inputs Be Better Filtered? Who Can Be Targeted by an XSS Attack? An XSS vulnerability is an attack that allows a website to display malicious content. This type of vulnerability is caused by a flaw in the document object model (DOM), which is the part of the browser responsible for rendering web pages. As websites have become larger and more complex, processing has moved to the client side. This means that modern single-page applications need only a page load time, and communication between the server and the client can be asynchronous. To read more, go to: https://lnkd.in/gfTNr5QS

🌟 Day 13 of my Node.js Zero to 1 blog series is here! 🚀 Today, we're exploring authentication and authorization using JWT (JSON Web Tokens). Learn how to secure your Node.js applications with JWT, manage user sessions, and protect routes. Perfect for developers looking to implement robust security measures! #NodeJS #JWT #WebDevelopment #Authentication #Authorization #Coding #Programming #Tech #BlogSeries

Security headers We can add these headers to all our responses by adding a middleware that will add the headers to every response. X-Frame-Options - indicates whether or not a browser should be allowed to render a page in a frame object, which is used to avoid click-jacking attacks by ensuring that their content is not embedded into other sites. X-Content-Type-Options - indicates that the MIME types advertised in the Content-Type headers should be followed, which is used to avoid MIME-type sniffing. X-XSS-Protection - a feature of some browsers that stops pages from loading when they detect reflected cross-site scripting (XSS) attacks. Note that this header is non-standard and is not on a standards track, meaning that it will not work for every user. This is also largely unnecessary in modern browsers with implementations of content security policies. Cache-Control - controls caching in browsers and shared caches. By setting the value to no-cache, we instruct the cache to always validate the content with the origin server before returning it to the requester, which ensures that the requester will always get the newest version of the content. When using these headers, we must have in mind the fact that they are only instructions for the browsers. This means that we're depending on the "goodwill" of browser developers to implement the mechanisms we advise using. Since most of our users will use one of the more popular browsers which do support these headers, this will not be an issue for them (and us), but these headers do not guarantee protection like other security guidelines which are implemented on the server side.

Successfully completed the PortSwigger Web Security Academy lab on remote code execution by exploiting a file upload vulnerability to upload a malicious web shell. This hands-on exercise involved bypassing file upload restrictions and executing arbitrary commands on the server, demonstrating a critical vulnerability often found in web applications.

🚨 Friendly reminder to the developer community: Be cautious with VSCode (or any IDE) extensions. These tools are increasingly targeted by malicious actors. Here’s how you can stay safe: 🔹 Install Wisely: Only install extensions necessary to run projects. Remove them when they are no longer needed. 🔹 Verify Source: Check the source and developers behind an extension. Look for ratings, reviews, and update history to ensure credibility. 🔹 Permission Check: Be wary of extensions requesting unnecessary permissions. 🔹 Use Security Tools: Ensure you have antivirus or endpoint detection solutions in place. These should be part of your standard setup in any case. 🔹 Monitor Behavior: Stay alert to unusual VSCode behavior, such as increased memory usage or network traffic. 🔹 Stay Updated: Keep your IDE and extensions up to date to benefit from the latest security patches. Let’s keep your development environments secure! 💻🔒
