There are many ways attackers can target web applications (websites that let you connect to software using a browser) to steal confidential information and introduce malicious code and take over your computer or device. These attacks exploit weaknesses in components such as web apps or content management systems. They also attack web servers.

Web app attacks constitute the majority of security threats. In the last decade attackers have developed their capabilities in identifying and exploiting vulnerabilities that affect the perimeter defenses of applications. Attackers are able to circumvent the most common defenses by leveraging methods like phishing, social engineering and botnets.

A phishing attack involves tricking victims into clicking on an email link that has malware. This malware is downloaded onto the victim’s system and grants attackers access to systems or devices. Botnets are groups of infected and compromised connected devices, that attackers use to launch DDoS attacks and spread malware, as well as to perpetuate fraud on ads, and so on.

Directory traversal attacks use movement patterns to gain unauthorised access to files, configuration databases, and other files on the website. Input sanitization is required to defend against this type of attack.

SQL injection attacks aim to target the database storing crucial information about websites and services by injecting malicious code that permit it to obfuscate and reveal information that it wouldn’t normally reveal. Attackers can then execute commands that dump databases, as well as other.

Cross-site scripting attacks (or XSS), insert malicious code on a trusted site to take over the browsers of users. This allows attackers to access session cookie and confidential information, impersonate users alter content, and much more.
