This MOOC will teach you how to hack web applications with command injection vulnerabilities on a website hosted by your AWS Linux instance. Learn how to search for valuable information about a Linux system with LAMP services and how to deposit and hide Trojans that can be used in future exploits. These web apps can be patched using input validation and regular expression. This security design pattern will help you avoid injection vulnerabilities. It involves input validation, replacing generic system calls by specific function calls. Learn how to hack web applications with SQL injection vulnerabilities. You'll also learn how passwords and user profile information can be retrieved. These vulnerabilities can be fixed using input validation and SQL parameter binding. The hacking method, Nessus tool to scan vulnerabilities, Kali Linux, for penetration testing and Metasploit Framework will be taught. This framework allows you to gain access and deploy keyloggers, remote VNC server injection, and other methods that can be used to gain access and compromise vulnerable Windows Systems. You will also learn about buffer overflow attacks, virtual memory layout and security. Learn how to clone Kali instances with AWS GPU support, and perform hashcat password cracking via dictionary attacks and known patterns mask attacks.
