This rule detects command-and-control (C2) communication patterns associated with the 'soraki-proxy.workers.dev' domain, a Cloudflare Workers-hosted proxy service. Additionally, it identifies potential malicious mTLS implants by flagging non-standard TLS handshakes that use self-signed or auto-generated certificates missing standard organization (O) fields in the subject DN.
Detects specific DNS-over-HTTPS (DoH) requests made to Google resolvers containing suspicious domain patterns associated with potential C2 infrastructure (QuietRacket). This includes both the identification of the DoH API call for a specific TXT record and the preceding TLS session initiation to the DoH provider.
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 high-rate scanning and automated service probing patterns consistent with network reconnaissance. This includes tracking TCP SYN floods to external segments, excessive HTTP/login requests, and automated fingerprinting probes (e.g., favicon or admin panel enumeration). The rule accounts for common uptime monitoring services to minimize false positives.
Detects successful authentication events using known default or low-privileged Cisco Firepower Management Center (FMC) service accounts, or IDS alerts (Snort SID 66883) associated with credential abuse activity potentially related to CVE-2026-20316.
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 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 attempts to access sensitive files like environment variables (.env), cloud provider credentials (AWS/Azure), or Terraform state files via a web server interface, specifically targeting Vite development server deployments.
Detects attempts to access sensitive files like environment variables (.env), cloud provider credentials (AWS/Azure), or Terraform state files via a web server interface, specifically targeting Vite development server deployments.
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.
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 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.
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.
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.
