Attackers are exploiting unpatched TLS listeners by flooding them with incomplete ACME ALPN handshakes to exhaust server-side resources like goroutines and worker threads.

This brief details how attackers exploit Local File Inclusion (LFI) vulnerabilities on web servers such as Nginx, Apache, IIS, and Traefik, by using directory traversal or direct sensitive file path requests to disclose system information, credentials, and configuration files, potentially leading to remote code execution and system compromise.

This brief details the detection of potential SQL injection (SQLi) attempts against web servers by identifying common SQLi patterns in URLs and query strings, used by threat actors for reconnaissance, data exfiltration, or command execution, aiming for sensitive information disclosure or system compromise.

Attackers are actively exploiting Server-Side Request Forgery (SSRF) vulnerabilities in public-facing web applications to access cloud instance metadata services, such as those on AWS, GCP, and Azure, to harvest temporary credentials and sensitive instance details.

This rule detects potential Remote File Inclusion (RFI) activity on web servers by identifying HTTP GET requests that attempt to access sensitive remote files through directory traversal techniques or known file paths, potentially leading to information disclosure or further compromise.

This rule detects potential web server discovery or fuzzing activity by identifying a high volume of HTTP GET requests resulting in 404 or 403 status codes from a single source IP address within a short timeframe, indicating attackers discovering hidden resources for targeted attacks.

Detection of web server discovery or fuzzing activity indicated by a high volume of HTTP GET requests resulting in 404 or 403 status codes originating from a single source IP address within a short timeframe, suggesting attempts to discover hidden resources.

Detection of potential web server discovery or fuzzing activity characterized by a high volume of HTTP GET requests resulting in 404 or 403 status codes originating from a single source IP address within a short timeframe, indicating attackers are probing for hidden resources.
