Detects outbound HTTP requests to known domains or domains following a specific URI pattern associated with the delivery of SilverFox malware payloads.
Detects network traffic (TLS SNI or HTTP Host) to known domains associated with Adversary-in-the-Middle (AiTM) phishing campaigns. These domains mimic passkey, SSO, or account security portals to steal credentials and session cookies.
Detects anomalous access to WSO2 API Manager Store and Publisher endpoints involving the retrieval of sensitive information like consumer keys and secrets. The rule specifically targets requests authenticated with JWTs that exhibit headers indicative of 'alg=none' or other unsupported/forged algorithm patterns, often associated with CVE-2026-5430 exploitation attempts. The rule uses statistical baseline monitoring to identify volume spikes in requests to these sensitive paths.
Detects incoming HTTP requests to the WSO2 admin API endpoint that utilize a JSON Web Token (JWT) with the 'alg=none' algorithm, indicating an attempt to bypass authentication via JWT token forgery (CVE-2026-5430).
Detects attempts to exploit a vulnerability in WSO2 API Manager and Traffic Manager that allows for authentication bypass by utilizing a malformed JWT with the 'alg=none' header. Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.
Detects download or installation attempts of specific trojanized versions (2.35 and 2.36) of the Admin Menu Editor Pro plugin, which were distributed via a compromised update channel on adminmenueditor.com.
Detects network traffic directed towards Microsoft Graph API that utilizes the 'python-httpx' User-Agent. This combination is often associated with automated scripts, potentially used by adversaries (e.g., Storm-3121/Storm-3032) for automated data collection and exfiltration from Microsoft 365 environments.
Detects unauthorized exploitation attempts against the LiteLLM Model Context Protocol (MCP) endpoint. The rule monitors for a specific malformed Authorization header pattern (short, non-standard token) associated with CVE-2026-59822, indicating potential vulnerability scanning or exploitation of the service.
Detects successful exploitation attempts targeting Vite development servers via chained access-control bypass vulnerabilities (CVE-2025-30208, CVE-2025-31125, CVE-2024-45811). The rule identifies malicious GET requests using the /@fs/ endpoint with specific query parameters, resulting in a successful HTTP 200 response, while originating from non-internal IP addresses.
Detects successful exploitation attempts targeting Vite development servers via chained access-control bypass vulnerabilities (CVE-2025-30208, CVE-2025-31125, CVE-2024-45811). The rule identifies malicious GET requests using the /@fs/ endpoint with specific query parameters, resulting in a successful HTTP 200 response, while originating from non-internal IP addresses.
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 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 an exploitation attempt against the Vite Development Server (CVE-2026-39364) where an attacker uses specific query parameters to bypass file access restrictions and disclose sensitive files. The rule triggers on GET requests containing suspicious import-related query parameters and checks the resulting response to ensure a successful 200/206 status code and non-HTML content type.
Detects an exploitation attempt against the Vite Development Server (CVE-2026-39364) where an attacker uses specific query parameters to bypass file access restrictions and disclose sensitive files. The rule triggers on GET requests containing suspicious import-related query parameters and checks the resulting response to ensure a successful 200/206 status code and non-HTML content type.
Detects high-volume bursts of HTTP GET requests against specific paths associated with a Vite development server (/@vite/client, /@fs/, /src/) on port 5173. This pattern is indicative of automated reconnaissance or vulnerability scanning targeting an exposed development environment.
Detects network activity (DNS lookups, TLS SNI, and HTTP Host headers) associated with proxy infrastructure (iproyal.com and lightningproxies.net) known to be used by the HEAVYGRAM/CHOSEN BRICK threat actors to mask Telegram-based command and control traffic.
Detects incoming HTTP requests attempting to exploit a path traversal vulnerability in the GitLab Commits API (CVE-2026-85706). The rule looks for URI patterns containing directory traversal sequences (e.g., ../) targeting the repository commits endpoint.
Detects unauthenticated path traversal attempts targeting the GitLab repository commits API, specifically checking for URL-encoded and plain path traversal patterns (e.g., '../') in requests to the commits endpoint. This behavior is indicative of attempts to exploit vulnerabilities like CVE-2026-85706 to read arbitrary files outside the repository scope.
Detects outbound HTTP GET requests to a specific C2 domain 'luizestrelhashapr.online' masquerading as CSS file fetches. The request pattern uses a specific path '/google_api/' followed by predefined alphanumeric filenames, consistent with the KREMLIN malware browser extension's C2 polling mechanism.
Detects a two-stage pattern indicative of command-and-control (C2) communication. The rule identifies an initial request to a 'relays.json' endpoint (relay discovery) followed by a request to an 'api.php' endpoint (dispatcher decision) within a 5-second window, both using a 13-digit timestamp query string for cache-busting. It also captures single-stage 'api.php' requests as lower confidence alerts.
Detects network, HTTP, and DNS activity associated with the known three-tier delivery infrastructure (phishing sites, relay/dispatcher servers, and payload hosts) used by the threat actor UNC6671/SilverFox/Aurora. The rule distinguishes between high-confidence confirmed connections and low-confidence DNS-only events.
