Detects HTTP traffic patterns associated with the JSCeal malware family, specifically focusing on the exfiltration of crypto wallet information and account balances. The rule identifies communication to suspicious domains, unauthorized access to balance field names, and the masquerading of traffic to impersonate legitimate exchanges like Binance.
Detects anomalous TLS traffic directed at Binance or Bybit domains where the server certificate issuer is not from a known trusted certificate authority. This behavior is indicative of a Man-in-the-Middle (MITM) proxy interception, often associated with tools like JSCeal attempting to inspect or modify encrypted traffic to financial services.

Detects the download of a JavaScript module named JSCeal, which contains code indicative of an HTTPS interception proxy. The rule looks for Node.js-based server creation code combined with cryptographic operations like keypair generation, certificate creation, and PEM conversion, excluding common legitimate JavaScript libraries and CDNs.
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.

This rule detects high-volume, potentially automated POST requests to specific WordPress plugin endpoints (Super Forms and Elementor Pro) used for form submissions and file uploads. A high frequency of these requests from a single source within a short timeframe suggests active reconnaissance or exploitation attempts against these vulnerable components.
Detects inbound network traffic originating from IP addresses known to be associated with exploitation attempts targeting the Elementor Pro CVE-2026-32475 vulnerability. This rule monitors for connections to internal network assets from these identified threat actor sources.
Detects anomalous use of the 'X-Grafana-URL' header in conjunction with an 'Authorization: Bearer' token, indicative of an attempt to exfiltrate a service account token to an unauthorized or external domain, exploiting CVE-2026-15583.
Detects HTTP 301 redirection responses from a hardcoded IP address to an external domain associated with ProRAM command-and-control infrastructure.
Detects evidence of malicious file tampering on public CDNs (bootcdn.net, bootcss.com, staticfile.org) associated with the Funnull campaign. The rules identify specific malicious file hashes and anomalous oversized file sizes that indicate the presence of injected malicious loaders within common JavaScript libraries.

The rules identify specific malicious file hashes and anomalous oversized file sizes that indicate the presence of injected malicious loaders within common JavaScript libraries.
Detects inbound network connections from known IP addresses associated with the StyleSmuggler malware distribution, which is used to inject malicious scripts into web applications.
Detects DNS lookups, TLS SNI headers, and HTTP Host headers associated with the known StyleSmuggler malware download domain '247.cdnflare.xyz'.
Detects outbound network traffic associated with StyleSmuggler C2 infrastructure. The rule identifies established TLS connections to a known malicious IP address (99.84.67.186) and monitors for WebSocket-over-TLS traffic using the suspicious SNI 'windwsecurity.run'.
This rule detects an unauthenticated exploitation attempt against Magento GraphQL endpoints, specifically targeting the 'styles' parameter. The attack pattern involves sending a malformed request to the /graphql endpoint with an 'X-TRACE-' header, which is indicative of the StyleSmuggler vulnerability exploit.
Detects DNS queries for known typosquatted time-sync domains and associated UDP traffic on port 123 (NTP) utilized by the StyleSmuggler malware for command and control purposes.
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 malicious traffic directed towards unpkg.com associated with the 'Beamglea' campaign. The rule specifically monitors for connections to known malicious npm-mirrored packages or pages serving fake Cloudflare CAPTCHA challenges, which are common tactics for credential theft and browser-based exploitation.
This rule detects a multi-stage reconnaissance behavior where an internal host first establishes a TLS connection to speedtest.net, followed immediately by high-volume TCP SYN packet activity (100+ events in 10 seconds), characteristic of network scanning tools like Masscan.
Detects high-frequency login attempts using the Dahua Easy4IP protocol. The rule flags multiple login opcode requests (identified by specific byte patterns 0xFF followed by 0x00A0) originating from the same source within a 60-second window, which is indicative of an automated brute-force or credential-stuffing attack targeting vulnerable IoT devices.
