The following queries pivot from an IP address assigned to a machine to the relevant machine or logged-on users.

Detects instances where an FTP service on an OpenCanary honeypot has had a login attempt. This indicates an adversary is attempting to access or interact with the honeypot's services, which could be part of reconnaissance, initial access, or lateral movement activities.
Detects connections from routable IPs to an RDP listener. Which is indicative of a publicly-accessible RDP service.
The analytic detects the creation of a Kubernetes NodePort service, which exposes a service to the external network. It identifies this activity by monitoring Kubernetes Audit logs for the creation of NodePort services. This behavior is significant for a SOC as it could allow an attacker to access internal services, posing a threat to the Kubernetes infrastructure's integrity and security. If confirmed malicious, this activity could lead to data breaches, service disruptions, or unauthorized access to sensitive information.
Detects instances where a VNC service on an OpenCanary node has had a connection attempt. This indicates an adversary attempting to connect to a VNC service, likely for remote access or reconnaissance.
Detects inbound network connections to ports 5985 or 5986, which are commonly used for PowerShell Remoting (WinRM). This rule specifically looks for EventID 5156 (Windows Filtering Platform Connection) with a LayerRTID of 44, indicating an inbound connection.
This detection excludes known namped pipes accessible remotely and notify on newly observed ones, may help to detect lateral movement and remote exec using named pipes
Detects basic PowerShell Remoting (WinRM) by monitoring for network inbound connections to ports 5985 OR 5986
