Detects rapid enumeration of sensitive system information files (CPU info, command line, device ID, node data) by processes executing from transient or commonly abused directories like /tmp, /var/tmp, or /dev/shm, as well as processes identified with specific malware naming patterns. This behavior often indicates an initial discovery phase by a threat actor or automated malicious agent.

This rule detects activities associated with the 'clean.sh' script often used by cryptocurrency miners to remove competing miner processes, terminate services, clear persistence mechanisms (cron jobs), and delete artifacts from temporary directories like /tmp, /var/tmp, or /dev/shm.

Detects a suspicious sequence of events involving the execution of 'setup.sh', the subsequent creation of a hidden file in temporary directories, and the deletion of specific architecture-named files (redtail.*). This behavior is indicative of a malware loader or droppers attempting to install and then remove traces of its components.

Detects instances where a RedTail malware variant enumerates processes via the /proc filesystem to identify and terminate previous instances of itself using a kill signal.

Detects anomalous SSH sessions originating from potentially suspicious IP addresses that utilize an 'SSH-2.0-Go' banner and immediately perform file creation operations associated with the RedTail botnet (e.g., shell scripts or architecture-specific binaries).
Detects the creation of PHP files within the 'wp-content/uploads/elementor/forms/' directory of a WordPress installation. This behavior is highly suspicious as it often indicates an attempt by an attacker to deploy a web shell or other malicious script following successful exploitation of the Elementor plugin, which allows for arbitrary file uploads.
Detects anomalous, high-volume unauthenticated POST requests to the Elementor Pro 'admin-ajax.php' endpoint with the 'elementor_pro_forms_send_form' action. This behavior is indicative of potential exploitation attempts or reconnaissance associated with the Elementor Pro file upload vulnerability (CVE-2026-32475).

This behavior is indicative of potential exploitation attempts or reconnaissance associated with the Elementor Pro file upload vulnerability (CVE-2026-32475).
Detects incoming HTTP POST requests targeting the 'admin-ajax.php' endpoint with parameters associated with a malicious file upload exploit against Elementor Pro (CVE-2026-32475). The rule specifically looks for the 'elementor_pro_forms_send_form' action and the presence of PHP file extensions within form fields, indicating an attempt to upload a web shell.
Detects the disabling of host-based firewalls (Windows Filtering Platform/Advanced Firewall, iptables, or nftables) via command-line tools. The rule excludes common management tools, system accounts, and events where the firewall is re-enabled within a short timeframe, effectively filtering for potentially unauthorized attempts to impair security defenses.
Detects potential remote service session hijacking by monitoring for RDP session ID reuse by a different user or unauthorized SSH session reattachment (e.g., tmux/screen hijacking). It correlates logon events with process execution to identify instances where an existing session is accessed by an account other than the original owner, while excluding legitimate service/support account activity.
