This rule monitors for internal network connection attempts initiated by the 'mcp-grafana' process to destinations it has not contacted in the previous 14 days. By establishing a baseline of legitimate data source connections, the rule alerts when the process performs a rapid fan-out or discovery against multiple new internal hosts, which may indicate unauthorized network reconnaissance or lateral movement attempts by the Grafana service.
This rule detects the use of raw sockets by 'ERAAgent.exe' by monitoring for socket I/O control (Ioctl) operations involving 'SIO_RCVALL'. This configuration, often associated with promiscuous mode, allows an application to capture all network traffic received by the network interface, a behavior commonly used by network sniffing tools or malicious implants to intercept sensitive data.
This rule detects a high volume of inbound network connection attempts to the default Redis port (6379) originating from local loopback or local host addresses, excluding known legitimate Redis and web server processes. This activity is indicative of potential unauthorized access attempts or exploitation of local Redis instances.
Detects high-frequency requests for 'tools/list' from a single source IP across multiple unique destination hosts. This pattern is indicative of a breadth-first scan attempting to identify reachable Model Context Protocol (MCP) servers, rather than typical legitimate client-to-server communication.
This rule monitors for internal network connection attempts initiated by the 'mcp-grafana' process to destinations it has not contacted in the previous 14 days. By establishing a baseline of legitimate data source connections, the rule alerts when the process performs a rapid fan-out or discovery against multiple new internal hosts, which may indicate unauthorized network reconnaissance or lateral movement attempts by the Grafana service.
This rule detects a high volume of inbound network connection attempts to the default Redis port (6379) originating from local loopback or local host addresses, excluding known legitimate Redis and web server processes. This activity is indicative of potential unauthorized access attempts or exploitation of local Redis instances.
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 TCP SYN connection attempts originating from an internal device, which is indicative of a port scanning behavior typically used for network service discovery.
Detects probing of common sensitive paths such as .env, .git, wp-admin, phpmyadmin.
Detects User-Agent strings belonging to common attack/scanning tools.
This rule monitors for internal network connection attempts initiated by the 'mcp-grafana' process to destinations it has not contacted in the previous 14 days. By establishing a baseline of legitimate data source connections, the rule alerts when the process performs a rapid fan-out or discovery against multiple new internal hosts, which may indicate unauthorized network reconnaissance or lateral movement attempts by the Grafana service.
This rule monitors web server logs (IIS, W3C, and Azure Application Gateway) for incoming traffic that matches known malicious or automated vulnerability scanners, as well as requests for common system fingerprinting paths (such as /server-status or /.git/config). The rule aggregates these hits by source IP address to identify potential active reconnaissance or vulnerability scanning attempts.
This rule detects a high volume of inbound network connection attempts to the default Redis port (6379) originating from local loopback or local host addresses, excluding known legitimate Redis and web server processes. This activity is indicative of potential unauthorized access attempts or exploitation of local Redis instances.
This rule detects high-frequency account and email address enumeration attempts. It monitors syslog data for SMTP commands such as VRFY, EXPN, or RCPT TO, and analyzes Microsoft Entra ID (SigninLogs) for authentication failures specifically associated with error code 50034 (user not found). Both behaviors are indicative of an adversary attempting to validate user identities within an environment, often as a precursor to targeted phishing or brute-force attacks.
Detects anomalous, high-frequency inbound TCP connection attempts to port 102 (S7comm), which is used by Siemens S7 PLCs. This behavior is indicative of automated network scanning or reconnaissance targeting industrial control system (ICS) infrastructure.
This rule monitors for active reconnaissance or scanning behavior by detecting a single source IP interacting with a high number of distinct ports/hosts within a short time frame (NetworkScan) or accessing a high number of distinct URI paths/404 errors (WebContentScan).
This rule detects the use of raw sockets by 'ERAAgent.exe' by monitoring for socket I/O control (Ioctl) operations involving 'SIO_RCVALL'. This configuration, often associated with promiscuous mode, allows an application to capture all network traffic received by the network interface, a behavior commonly used by network sniffing tools or malicious implants to intercept sensitive data.
Detects potential web reconnaissance or scanning activity against Microsoft IIS servers. The rule identifies suspicious behavior by monitoring for high frequencies of distinct URI requests, excessive 404 Not Found status codes indicative of path brute-forcing, and the presence of known security scanning user-agents.
Detects anomalous DNS activity characterized by either unauthorized DNS zone transfer (AXFR/IXFR) requests or aggressive subdomain enumeration patterns from external IP addresses. This rule monitors for high volumes of non-standard DNS queries or distinct subdomain lookups within a 15-minute window, which are common precursors to reconnaissance activities.
Detects repeated attempts to establish S7comm connections to a Programmable Logic Controller (PLC) on port 102. This behavior is indicative of network reconnaissance or scanning targeting Industrial Control Systems (ICS).

This configuration, often associated with promiscuous mode, allows an application to capture all network traffic received by the network interface, a behavior commonly used by network sniffing tools or malicious implants to intercept sensitive data.
