If the said account is your email account that you use for logins to your social media, then you are doomed. Why? Because nearly all known password reset links are sent via email. If a malicious individual has full access to said email, they can use it to reset passwords on all the accounts that you use said email to login with. Then you will be locked out of your email, and all the aforementioned accounts. We know this...

We have all heard of a proxy before. It acts as an intermediary for requests between the client and the internet. A reverse proxy, however, is not so familiar to the average web user. A WAF (Web Application Firewall) is a type of reverse proxy which sits outside of web applications in production and inspects incoming traffic. If they see a malicious traffic pattern, they will block it. Web application firewalls typically monitor HTTP and HTTPS traffic between a web application and the internet. The most common use for WAFs is to protect against SQL injections attacks, cross-site scripting...

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...

There are numerous ways that a site’s security can be compromised. One possible method of attack is an injection attack (i.e. the attacker provides untrusted input to a program).

What is a Proxy Server?

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...
