    Required data: XDR Agent
    Detector tags: Abnormal Communication Analytics
    Attacker's goals: Communicate with malware running on your network to control malware activities, perform software updates on the malware, or to take inventory of infected machines. Additionally, establish command and control channels for remote malware control, conduct discovery activities to gather information about the target environment, or exfiltrate sensitive data from compromised systems.
    Investigative actions: Identify the process contacting the remote host and determine whether the traffic is malicious. Look for other endpoints on your network that are also periodically contacting the same external host. Inspect the domain or URL for malicious indicators or its presence in threat intelligence feeds and reputation lists.
