ATT&CK tactics: Command and Control (TA0011)ATT&CK techniques: Application Layer Protocol (T1071)Required data: XDR AgentAttacker'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.Investigative actions: Identify the process contacting the remote domain and determine whether the traffic is malicious. Look for other endpoints on your network that are also periodically contacting the suspicious domain. Inspect the domain or URL for suspicious indicators or its presence in malicious reputation lists.Variations
