This rule detects inbound HTTP requests targeting a Vite development server that attempt to access the '.env' configuration file via the '//@fs/' path, which is a known technique for sensitive file exposure in misconfigured Vite environments.
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 DNS queries for 'd.clash-verge-upgrade.com', a domain identified as a Command and Control (C2) fallback transport mechanism for the ProRAM malware.
Detects inbound HTTP POST requests to the /paypal/transparent/response/ endpoint containing encoded PHP webshell payloads, specifically attempting to execute base64-decoded code via eval.
Detects HTTP GET requests to '/api.php?t=' containing a 13-digit timestamp identifier, followed by a response body containing 'download_link'. This pattern is indicative of the SilverFox malware relaying instructions or stage-two payload delivery.

This rule detects IDS/IPS or vulnerability management alerts triggered by exploitation attempts targeting the Cisco IOS XR control plane, specifically related to CVE-2026-20212.
Detects country-coded lure path requests (/eg, /ma) followed by a cloaking differential response (desktop UA blocked with 404, mobile UA served content). Fixed a regex bug where the original pattern matched any path merely starting with 'eg' or 'ma' (e.g. /egg.jpg, /mail, /manifest.json) instead of the exact path segment.
Detects sensitive data exfiltration attempts (PII, credit card, OTP) via HTTP POST requests to suspicious lookalike domains, followed by a WebSocket connection to known IronToll C2 infrastructure.

This rule monitors TLS traffic for a specific combination of certificate issuer Common Name (CN) matching 'YE1' and Server Name Indication (SNI) hostnames using known disposable or high-risk top-level domains (TLDs). This behavior is associated with the IronToll campaign, often indicative of command-and-control communication or malicious infrastructure staging.

Detects high-frequency POST requests to the JFrog Artifactory '/access/api/v1/tokens' endpoint, which is indicative of mass exploitation attempts targeting vulnerabilities (CVE-2026-82329) against administrative token management.

Detects DNS A record lookups for the domain 'mail.uaiubifas.top', which is associated with GRAYRABBIT C2 activity linked to UNC3569. This domain is known to be used for command and control communications.
