This rule detects HTTP GET requests for static image assets (jpg, jpeg, png, gif, webp, svg) where the Referer header originates from a .shop top-level domain. This behavior may indicate an unauthorized use of brand image assets, often associated with fraudulent e-commerce sites or phishing campaigns using lookalike or disposable infrastructure.
This rule detects high-volume DNS resolution of domains ending in the .shop TLD from internal hosts, which may indicate interaction with a cluster of infrastructure used by the DoppelCart fake-shop campaign.
This rule detects high-volume DNS resolution of domains ending in the .shop TLD from internal hosts, which may indicate interaction with a cluster of infrastructure used by the DoppelCart fake-shop campaign.
Detects high-frequency DNS query responses for domains ending in '.shop' from external sources within a 10-minute window. This behavior is indicative of domain churn often associated with 'DoppelCart'-style fake e-commerce shop infrastructure.
Detects high-frequency DNS query responses for domains ending in '.shop' from external sources within a 10-minute window. This behavior is indicative of domain churn often associated with 'DoppelCart'-style fake e-commerce shop infrastructure.
Detects high-frequency DNS query responses for domains ending in '.shop' from external sources within a 10-minute window. This behavior is indicative of domain churn often associated with 'DoppelCart'-style fake e-commerce shop infrastructure.
Detects high-volume, potentially malicious activity where a client requests a large number of distinct hostnames ending in .shop from a single destination IP address within a short time frame, which may indicate infrastructure used for phishing or fraudulent e-commerce storefronts similar to DoppelCart-style activity.
Detects high-volume, potentially malicious activity where a client requests a large number of distinct hostnames ending in .shop from a single destination IP address within a short time frame, which may indicate infrastructure used for phishing or fraudulent e-commerce storefronts similar to DoppelCart-style activity.
Detects network communication to Firebase infrastructure (.firebaseio.com) initiated by Android devices, which may indicate command-and-control (C2) activity associated with the Mantax Otax malware family. This rule tracks initial connections and should be correlated with specific suspicious domains for higher confidence.
Detects high-frequency, repeated access to a specific fraud-tracking or canary token link by sources utilizing rotating VPNs or proxies over an extended period. This behavior is indicative of automated probing or credential validation attempts associated with the Phantom Deal campaign.
This rule detects network traffic indicative of the PEEP Browser RAT, specifically HTTP beacons targeting the URI path '/api/commands'. It monitors for unique HTTP headers ('X-PEEP-Agent-Id', 'X-PEEP-Agent-Key') and connections to known malicious infrastructure.
Detects Server-Side Request Forgery (SSRF) attempts against Grafana instances using the 'X-Grafana-URL' header. The rule identifies requests attempting to access internal network ranges, link-local addresses, or cloud metadata endpoints (e.g., 169.254.169.254, localhost) via the Grafana MCP interface, particularly when non-GET HTTP methods are used to potentially mutate internal resources.
Detects unauthenticated attempts to invoke Grafana API tools via the Model Context Protocol (MCP) by utilizing spoofed Mcp-Session-Id headers while bypassing bearer token authentication requirements. This primarily targets unauthorized access to API functionality on Grafana instances configured with bearer-token authentication (v1.1.0+).
Detects anomalous use of the 'X-Grafana-URL' header in conjunction with an 'Authorization: Bearer' token, indicative of an attempt to exfiltrate a service account token to an unauthorized or external domain, exploiting CVE-2026-15583.
This rule detects outbound network connections from internal hosts to specific IP addresses associated with known AlexHost infrastructure identified as command-and-control (C2) servers for the Bandook Remote Access Trojan (RAT), which is utilized by the threat actor Dark Caracal.
Detects HTTP 301 redirection responses from a hardcoded IP address to an external domain associated with ProRAM command-and-control infrastructure.
Detects network activity associated with the ProRAM C2 infrastructure. The rule monitors for DNS resolutions, TLS SNI field matches, and specific HTTP WebSocket upgrade patterns directed towards the 'clash-verge-upgrade.com' domain.
This rule detects attempted exploitation of Adobe Commerce (Magento) via GraphQL, specifically targeting Template Property Poisoning through malicious 'styles' array injection as observed in the StyleSmuggler campaign (CVE-2025-54236).
Detects suspicious GET requests to the Magento '/customer/section/load/' endpoint with specific parameters ('sections=customer' and 'force_new_section_timestamp=true'). These requests are indicative of reconnaissance activity related to the StyleSmuggler campaign, potentially associated with exploitation of Magento vulnerabilities such as CVE-2025-54236.
Detects DNS queries for known typosquatted time-sync domains and associated UDP traffic on port 123 (NTP) utilized by the StyleSmuggler malware for command and control purposes.
Detects malicious traffic directed towards unpkg.com associated with the 'Beamglea' campaign. The rule specifically monitors for connections to known malicious npm-mirrored packages or pages serving fake Cloudflare CAPTCHA challenges, which are common tactics for credential theft and browser-based exploitation.
