This rule monitors for DNS queries, HTTP requests to '/cli/check', and TLS SNI traffic directed towards the domain 'coder-infra.com', which is associated with a suspected compromise of a Coder registry.
Detects network activity (TCP, DNS, and HTTP) directed towards a known rogue infrastructure IP identified in a supply chain compromise affecting the Coder registry. The rule alerts on attempts to resolve or communicate with this infrastructure to download backdoored Terraform modules or interact with malicious resources.

Detects high-rate scanning and automated service probing patterns consistent with network reconnaissance. This includes tracking TCP SYN floods to external segments, excessive HTTP/login requests, and automated fingerprinting probes (e.g., favicon or admin panel enumeration). The rule accounts for common uptime monitoring services to minimize false positives.

Detects high-frequency PUT requests to known S3-compatible cloud storage providers using the rclone user-agent, which is a common indicator of bulk data exfiltration or unauthorized backup activity by attackers.

Detects HTTP traffic patterns associated with the JSCeal malware family, specifically focusing on the exfiltration of crypto wallet information and account balances. The rule identifies communication to suspicious domains, unauthorized access to balance field names, and the masquerading of traffic to impersonate legitimate exchanges like Binance.
Detects the download of a JavaScript module named JSCeal, which contains code indicative of an HTTPS interception proxy. The rule looks for Node.js-based server creation code combined with cryptographic operations like keypair generation, certificate creation, and PEM conversion, excluding common legitimate JavaScript libraries and CDNs.
Detects repeated HTTP requests targeting the '/cgi-bin/' path on Dahua camera web interfaces with a specific user-agent string ('CGI Brute'). This behavior is characteristic of an automated brute-force campaign attempting to gain unauthorized access to camera web administration interfaces.
This rule detects rapid SYN packet patterns from external sources targeting the Dahua proprietary port 37777, characteristic of network scanning tools like Masscan attempting to discover or identify vulnerable Dahua devices.
This rule detects a high volume of TCP synchronization (SYN) packets from external sources directed at a Cisco IOS XR network device. This behavioral pattern is indicative of a resource exhaustion denial-of-service (DoS) attack, potentially attempting to exploit vulnerabilities such as CVE-2026-20274 by flooding the control plane.
Detects network activity (HTTP, TLS SNI, and DNS) associated with the domain 'noht1ng.top', which is linked to the GRAYRABBIT malware utilized by the threat actor UNC3569.

Detects network activity (HTTP, TLS SNI, and DNS) associated with the domain 'noht1ng.top', which is linked to the GRAYRABBIT malware utilized by the threat actor UNC3569.
Detects DNS queries originating from an internal host to 'mail.uaiubifas.top', which is associated with GRAYRABBIT command-and-control (C2) activity.
Detects attempts to exploit CVE-2023-2825, a path traversal vulnerability in GitLab. The rule monitors HTTP GET requests to the /uploads/ endpoint containing directory traversal sequences (e.g., ../ or encoded variants) in the URI, indicating an effort to access restricted files on the system.
Detects established outbound network connections on TCP port 853 (DNS-over-TLS) to known C2 infrastructure associated with the RedTail malware. The rule monitors for both connection attempts to anomalous resolvers and specific TLS handshake patterns characteristic of RedTail C2 activity.
Detects mass automated POST requests directed at the 'super_submit_form' action within the 'admin-ajax.php' endpoint of the Super Forms WordPress plugin, indicative of exploitation attempts or vulnerability scanning against CVE-2026-14894.
Detects a malicious HTTP POST request targeting the Elementor Pro WordPress plugin's 'elementor_pro_forms_send_form' action. The rule looks for a specific attempt to bypass file upload restrictions by manipulating the array index of form fields to upload a PHP file via the 'admin-ajax.php' endpoint.
