Detects incoming HTTP GET requests targeting Vite development server environments that utilize suspicious query parameters typically associated with vulnerability exploitation (e.g., directory traversal or sensitive file access). The rule specifically flags requests where the User-Agent string contains bot keywords but excludes verified IP ranges, suggesting an attempt to bypass security filters by spoofing crawler identities.

Detects path traversal attempts against a Vite development server by monitoring for various forms of URI encoding (single/double) and suspicious path patterns (e.g., /etc/passwd, .env, .git/config, /@fs/). The rule tracks these attempts using flowbits and alerts when a successful HTTP 200 response is received after a matching traversal request.

Detects outbound network traffic associated with the Tailscale VPN protocol, specifically identifying potential unauthorized or personal tailnet communication channels. The detection monitors for TLS SNI strings ending in '.ts.net' and WireGuard handshakes on UDP port 41641. These indicators are common to all Tailscale client activity and require environment-specific exclusions of sanctioned Tailscale infrastructure to minimize noise.

Detects indicators of cross-site scripting (XSS) attacks aimed at stealing web session cookies. The rule covers the injection of malicious scripts into client responses, anomalous CORS preflight responses that could facilitate data exfiltration, and subsequent HTTP callbacks or beaconing containing cookie data to external endpoints.

Detects the Iron Man System kit's known template artifact path, and separately its randomized per-deployment admin-panel path shape combined with a Host header on a disposable TLD. Splitting these and requiring the disposable-TLD host on the generic admin-path rule avoids matching legitimate multi-tenant apps or hardened CMS installs that use similar random-path-plus-/admin/ obfuscation on ordinary domains.

This rule detects a high volume of SCTP traffic targeted at internal systems, characterized by mass endpoint creation. This behavior is indicative of an exploit attempt against the 'sctp_diag' kernel component (CVE-2026-74469), which can lead to an out-of-bounds (OOB) write condition, potentially resulting in system instability or denial of service.

Detects high-frequency TLS sessions initiated from internal hosts to Microsoft identity, Graph API, and account management endpoints. This behavior often mimics legitimate interaction but may indicate an adversary rotating infrastructure, automating reconnaissance, or interacting with C2 channels disguised as legitimate SaaS traffic.

Detects a multi-stage sequence of network connections to Microsoft cloud services (login.microsoftonline.com, graph.microsoft.com, and data exfiltration endpoints like sharepoint.com) consistent with Storm-3121/Storm-3032 adversary activity. This rule is designed for IDS/IPS monitoring of traffic patterns indicating authentication, reconnaissance, and potential data exfiltration from Microsoft 365 environments.
