What is Web Attack?

There are many ways attackers are able to target web applications (websites that allow you to communicate with software via a browser) to steal confidential data, introduce malicious code, and take over your computer or device. These attacks exploit vulnerabilities in components like web apps as well as content management systems and web servers.

Web app attacks comprise the majority of security threats. Over the last 10 years attackers have refined their skills at identifying and exploiting vulnerabilities that can affect security perimeters for applications. Attackers have been able to bypass the most common defenses by leveraging techniques like phishing engineering and botnets.

A phishing attack involves tricking victims into clicking a email link that contains malware. This malware is downloaded to the victim’s PC and gives attackers access to devices or systems. Botnets are collections of compromised and infected devices, which attackers use to launch DDoS attacks and spread malware, as well as to perpetuate fraud through ads, and more.

Directory traversal attacks use patterns of movement to gain access to configuration files, files, files, and databases on the website. The need for input sanitization is to guard against this type of attack.

SQL injection attacks target the database that stores important data for websites and services by injecting malicious code, which allows it to override security controls and divulge information normally would not. Attackers then execute commands to dump databases, and many other things.

Cross-site scripting (or XSS) attacks insert malicious code on a trusted site to hijack browsers of users. This allows attackers to steal session cookies and confidential information to impersonate users, alter content, and many more.
