Like in SQL injection, XPath injection attacks occur when a website constructs an XPath query for XML data from user-supplied information. Thus, the issues that occur when using XML to store data are quite similar to those faces with SQL. XPath injection is a type of attack where malicious user input can be used to grant unauthorized access or reveal sensitive information such as XML document structure and content. This style of attack is carried out by making the user’s input be used in the construction of the query string. Unlike SQL attacks which depend on the SQL dialect used by...

Today we will discuss the latter and how to protect your site from XSS vulnerabilities. Cross-site Scripting is a type of computer security vulnerability which allows attackers to inject client-side scripts into web-pages viewed by other users. The attack is carried out when the victim actually...

What is a Proxy Server? What happens when you browse the web? You type an address on your browser and within few seconds (even less) you get the page you wanted. Without your knowledge, you might have used a proxy server to access the internet. A proxy server is an intermediary server which separates you from the website you want to access. When using a proxy server, the internet traffic initiated from you will flow through the proxy server to the destination. The destination website will send the results back to you through the proxy server (this doesn’t happen all the time). If...
Why Do Domains Get Blacklisted and How To Delist Them
What is a Blacklist? Depending on the source, the amount of daily spam emails being sent is anywhere between 80 to 95% of all emails sent on the internet that day. With such large numbers, most experts agree that manually sorting through your inbox to get rid of spam has become highly inefficient. As such, public blacklists of mail servers and IP addresses have been created to prevent repeat offenders from relaying spam. A blacklist is a list of blocked domains, email addresses or IP addresses. When a website gets on one of these lists, users can no longer access the site directly and...
