Detects a multi-stage attack pattern against publicly exposed AI service endpoints. The detection correlates: (1) Enumeration of sensitive AI/MCP-related API endpoints (minimum 3 distinct hits) in a 10-minute window; (2) Subsequent POST requests to AI service endpoints within 15 minutes of the enumeration; and (3) A spike of 5 or more server errors (HTTP 5xx) within 10 minutes following the POST activity. This pattern suggests automated reconnaissance followed by attempted exploitation of exposed AI model interfaces or orchestration services. Covers T1595.002, T1190

Detects network traffic associated with the Exvicy malware delivery chain. The rule identifies two behaviors: first, HTTP GET requests to a '/embed/' endpoint with specific 'embed=1' and 'host=cloudflare-check.net' parameters, and second, established TCP connections to a known command and control (C2) IP address related to the ClickFix social engineering delivery method.

Detects anomalous large-scale data transfers to external endpoints that exhibit patterns characteristic of the ShinyHunters group's SaaS bulk export and data exfiltration methods. The rule identifies suspicious HTTP requests to Salesforce API endpoints (e.g., batch jobs, bulk queries) accompanied by unusually large content payloads, followed by subsequent encrypted communication to non-whitelisted external destinations.

This rule detects network activity associated with the Sauron Loader malware. It monitors for TLS connections to known hardcoded C2 domains and identifies HTTP requests following a specific pattern of randomized command and control (C2) paths combined with suspicious User-Agent headers (Windows NT with Edge/Edg).

This rule detects potential command and control (C2) activity related to the AMOS (Atomic macOS) information stealer. It identifies a specific sequence of network requests where an initial registration beacon (POST /api/t) is followed by a shell agent request (GET /api/shell/agent) within 120 seconds, originating from the same destination IP and port.

This rule detects HTTP GET requests to a specific GitHub repository path (raw.githubusercontent.com/omskiwdcvoiuyfd0998/) identified as staging infrastructure associated with Konni/VelvetCake malware operations. This activity is indicative of a compromised host attempting to download malicious payloads or stage tools from actor-controlled infrastructure.

Detects suspicious HTTP POST requests to a URI path '/collect' containing specific telemetry parameters ('visitorId', 'timeOnPage', 'stage') characteristic of the 'ClickFix' social engineering campaign. This behavior is used by threat actors to simulate fake bot-protection challenges to trick users into executing malicious code.

Detects suspicious/unexpected usernames appearing in Cisco ISE access.log,
consistent with exploitation of CVE-2026-76460, an unauthenticated REST API
auth-bypass in Cisco ISE / ISE-PIC (CVSS 10.0, actively exploited, CISA KEV).
Cisco's own guidance is to hunt access.log for usernames not present in the
legitimate identity store; "dummyuser" is their published example artifact.

Detects malicious shell commands or scripts (e.g., bash, powershell, curl, wget) embedded within HTTP POST request bodies that appear to be AI agent tool-call payloads. This activity is indicative of prompt injection or AI tool-use exploitation attempts designed to execute arbitrary code on the underlying host or container.
