What is Web Attack?

A web attack is an attempt to exploit vulnerabilities in the website or parts of it. The attacks may involve the website’s content, web application or server. Websites offer many opportunities for attackers. They can gain unauthorized access to websites or obtain confidential information, or upload malicious content.

Attackers usually look for weaknesses in the structure or content of a website to steal data, control the website, or cause harm to users. Some common attacks are brute force attacks (XSS) and attacks on uploads of files, and cross-site scripting. Other attacks are carried out using social engineering techniques, such as malware attacks, phishing and that include trojans, ransomware or spyware.

Most website attacks are targeted at the web application. This is the software and hardware that websites use to display information to visitors. A hacker can attack an application on the web by exploiting its weaknesses, which include SQL injection, cross-site request forgery and reflection-based XSS.

SQL injection attacks exploit the database that web how to disable deepscreen avast 2016 applications use to store and deliver website content. These attacks can expose a variety of sensitive information, particularly passwords, account logins, and credit card numbers.

Cross-site Scripting attacks exploit flaws in the code of websites to display unauthorised images or text, hijack session information, and then redirect users to phishing websites. Reflective XSS also permits an attacker to execute arbitrary code.

A man-in-the-middle attack occurs when a third party intercepts communications between you and a web server. The attacker can modify the messages or spoof certificates, alter DNS responses and the list goes on. This is a powerful method to manipulate online activities.
