There are many ways hackers are able to target web applications (websites that let you interact with software using a browser) to steal sensitive information or introduce malicious http://neoerudition.net/avg-antivirus-review code and even take over your PC or device. These attacks exploit weaknesses in components such as web apps, content-management systems and web servers.
Web app attacks comprise a large portion of all security threats. In the last decade attackers have refined their abilities in identifying and exploiting vulnerabilities that affect security perimeters for applications. Attackers are able to evade the most common defenses by using techniques like phishing, social engineering, and botnets.
Phishing attacks trick victims into clicking on an email link with malware. This malware is downloaded to the victim’s system and grants attackers access to devices or systems. Botnets are compromised or infected devices that attackers use for DDoS attacks and spreading malware, sustaining fraud through ads, and much more.
Directory traversal attacks utilize patterns of movement to gain access to files, configuration databases, and files on websites. In order to protect against this kind of attack requires the proper sanitization of inputs.
SQL injection attacks are designed at the database that holds important information about a service or website by injecting malicious code that allow it to reveal information it would not normally reveal. Attackers can then execute commands that dump databases, as well as other.
Cross-site scripting (or XSS) attacks insert malicious code into a secure site to hijack browsers of users. This allows attackers to access session cookies and confidential information, impersonate users to alter content, and more.
