A web attack is an attempt to exploit weaknesses within the website or parts of it. The attacks may affect the content, web application or server of a website. Websites offer many opportunities for attackers to gain unauthorized access, get sensitive information, or create malicious content.
Attackers look for weaknesses in the structure or content of a website in order to gain access to data, take control of it, or even harm users. Some common attacks are brute force attacks (XSS) as well as attacks on file uploads, and cross-site scripting. Other attacks can be carried out using social engineering techniques, such as phishing, or malware attacks like ransomware trojans, worms, or spyware.
The most common attacks on websites are targeted at the web application, made up of hardware and software that a website uses to show information to visitors. Hackers can target a web application through its weaknesses, including SQL injection, cross-site request forgery, and reflection-based XSS.
SQL injection attacks leverage the underlying databases that web applications use to store and transmit website content. These attacks could expose sensitive information such as passwords, account logins and credit card numbers.
Cross-site scripting attacks rely on the flaws within a website’s code to display unauthorized text or images, steal session information, and redirect visitors to phishing websites. Reflective XSS allows an attacker execute any code.
A man-in-the-middle attack happens when an outside party intercepts the communication between you and the web server. The third party can modify messages, spoof certificates as well as alter DNS responses, and the list goes on. This is a very effective method of manipulating your online activities.
