A web attack is a technique to exploit weaknesses on websites or in portions of it. The attacks could involve the web application, content or server of a website. Websites can provide numerous opportunities for attackers to gain unauthorized access, steal private information, or http://neoerudition.net/top-3-best-free-vpn-for-deep-web even introduce malicious content.
Attackers look for weaknesses in the content or structure of a website in order to gain access to data, take control of it, or hurt users. Some of the most common attacks include brute force attacks and cross-site scripting (XSS), and file upload attacks. Other attacks are carried out using social engineering, like phishing, and malware attacks which include trojans, ransomware or spyware.
The majority of website attacks focus on the web application. This is the software and hardware used by websites to display information to visitors. Hackers can target the security of a website application by exploiting its weaknesses, including SQL injection, cross-site request forgery, and reflection-based XSS.
SQL injection attacks target databases that web applications depend on to store and distribute content. These attacks can expose sensitive information such as passwords, account logins, and credit card numbers.
Cross-site scripting attacks exploit flaws in the code of websites to display untrusted images or text, steal session information, and redirect users to phishing sites. Reflective XSS allows an attacker to execute unintended code.
A man-in-the middle attack occurs when a third party intercepts the communications between you and your web server. The third party is then able to modify the messages and spoof certificates, alter DNS responses, and so on. This is a way to manipulate online activities.
