Put this script in your htaccess To block these type of attacks.

This .htaccess code strengthens web application security by implementing protective measures against common attack vectors and unauthorized access. It enables URL rewriting with mod_rewrite, blocks requests from tools like Wget and Curl, enforces request rate limiting to mitigate Denial of Service attacks, and filters harmful query patterns to prevent SQL Injection. Additionally, it guards against XSS and related attacks by analyzing request methods and content types, denies access to sensitive files, disables directory browsing, and sets critical HTTP security headers. Finally, it logs blocked access attempts for monitoring and threat assessment.

This .htaccess code is designed to enhance the security of a web application by implementing various protective measures against common attack vectors and unwanted access. It begins by enabling the mod_rewrite module to facilitate URL rewriting. Several rules are defined to block requests from well-known tools and programming languages commonly used for web scraping or automated testing, such as Wget, Curl, and Nmap, as well as other potential bots. To protect against Denial of Service (DoS) attacks, it enforces request rate limiting, allowing specific IP addresses to bypass this restriction. The code also contains rules to identify and block SQL Injection (SQLi) attempts by filtering out harmful query patterns, as well as Cross-Site Scripting (XSS), Cross-Site Script Inclusion (XSSI), and XML External Entity (XXE) attacks by analyzing both the request method and content type. Sensitive files are explicitly denied access to enhance security, and directory browsing is disabled to prevent unauthorized viewing of directory contents. It also sets critical HTTP security headers to further safeguard the application. Lastly, any blocked access attempts are logged for monitoring purposes, enabling the website owner to review potential threats and improve their security posture.
