What is Web Attack?

There are a variety of ways that attackers are able to target web applications (websites that let you communicate with software via a browser) to steal sensitive information, introduce malicious code, and even take over your PC or device. These attacks exploit vulnerabilities within components like web apps such as content-management systems, web servers.

Web app attacks account for an enormous portion of security threats. In the past 10 years attackers have sharpened their skills in finding and exploiting vulnerabilities that can affect security perimeters for applications. Attackers can evade most common defenses using techniques like botnets, phishing, or social engineering.

Phishing attacks make victims click on an email link containing malware. The malware downloads onto their computer, which allows attackers to take over devices or systems for other goals. Botnets are collections of infected or compromised connected devices used by attackers to carry out DDoS attacks in spreading malware, perpetuating fraud on ads and more.

Directory (or path) traversal attacks use movements patterns to gain access to files on websites, their configuration files as well as databases. Input sanitization is necessary to protect against this type attack.

SQL injection attacks attempt to attack the database that stores crucial information about services and websites by injecting malicious code that permit it to obfuscate and reveal information that it wouldn’t normally divulge. Attackers can then execute commands, dump databases and more.

Cross-site scripting (or XSS) attacks insert malicious code inside a trusted site to take over browsers of users. This allows attackers to steal session cookies as well as confidential information, impersonate users, manipulate content and more.
