Detects high-volume authentication attempts against Fortinet network appliances where multiple distinct source IPs successfully authenticate against multiple distinct accounts matching specific administrative naming patterns. This pattern is indicative of potential credential stuffing or brute-force campaigns targeting edge infrastructure.
Detects potential remote code execution (RCE) attempts targeting vulnerable Sub-Store instances (versions < 2.38.2). The detection identifies web browsers making network connections to local ports (38324) associated with Sub-Store, followed by the spawning of shell processes (cmd, powershell, bash, sh) by the Node.js process hosting the application.
This rule detects a high volume of inbound network connection attempts to the default Redis port (6379) originating from local loopback or local host addresses, excluding known legitimate Redis and web server processes. This activity is indicative of potential unauthorized access attempts or exploitation of local Redis instances.
Detects potential remote code execution (RCE) attempts targeting vulnerable Sub-Store instances (versions < 2.38.2). The detection identifies web browsers making network connections to local ports (38324) associated with Sub-Store, followed by the spawning of shell processes (cmd, powershell, bash, sh) by the Node.js process hosting the application.
Detects high-frequency, automated requests to product and catalog pages within a short time window, characteristic of web scraping or catalog harvesting often used to feed fake-shop networks or build clone sites.
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).
This rule detects anomalous high-frequency, short-duration bursts of CAPWAP (Control and Provisioning of Wireless Access Points) traffic originating from external sources and targeting internal FortiGate devices. This behavior is indicative of automated exploitation attempts, specifically targeting known heap-grooming activities used in vulnerabilities like CVE-2023-27997, which rely on repetitive 'Add-Station' operations. Legitimate controller traffic is filtered by focusing on internal-to-internal communication patterns.
Detects incoming HTTP requests to sensitive LiteLLM endpoints (/mcp and /guardrails) which are typically intended for internal or controlled use. Exposing these to the public internet may allow unauthorized individuals to interact with, enumerate, or exploit the LiteLLM framework's capabilities.
Detects network-based exploitation attempts against Dahua Easy4IP P2P relay infrastructure, including reconnaissance probes, unauthorized relay usage, and credential theft attempts via WSSE authentication.
Detects inbound traffic, sign-ins, and email activity originating from the Anthropic IP range 160.79.104.0/21.
Detects inbound traffic, sign-ins, and email activity originating from the Anthropic IP range 160.79.104.0/21.
Detects inbound traffic, sign-ins, and email activity originating from the Anthropic IP range 160.79.104.0/21.
Detects instances where a development-oriented web server (such as Vite or Node.js) is configured to bind to all network interfaces ('0.0.0.0') and is simultaneously receiving inbound connections from non-private, external IP addresses on a common development port (5173). This rule filters out common CI/CD environments to focus on potentially insecure exposure of development tools to the public internet.
This rule monitors network traffic from internal devices and security logs for communication with a curated list of known malicious or suspicious scanner IP addresses, indicating potential reconnaissance or probing activity by external actors.

Detects a suspicious sequence of events on a Linux host: first, the 'iptables' firewall rules are flushed (-F), followed by the creation of an inbound TCP listener on a high port (>1024) and the activation of that port via iptables, finally correlating this with a network listener process residing in temporary or suspicious directories such as /tmp, /var/tmp, or /dev/shm. This behavior is indicative of a potential backdoor installation or temporary listener setup for unauthorized access.

This behavior is indicative of a potential backdoor installation or temporary listener setup for unauthorized access.
Detects specific suspicious processes (identified by hash or path) initiating a listening network connection on non-standard ports typically associated with honeypot captures, specifically referencing Cowrie-related paths or known malicious samples.
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).

This rule detects inbound HTTP GET requests to a specific IP address (103.86.86.244) requesting a file named 'deploy.ps1'. This behavior is characteristic of adversaries using PowerShell one-liners (cradles) like 'irm' (Invoke-RestMethod) or 'iex' (Invoke-Expression) to fetch and execute malicious scripts directly from a remote C2 infrastructure.
