## Investigation guide


## Triage and analysis


### Investigating PANW and Elastic Defend - Command and Control Correlation


### Possible investigation steps

- Investigate in the Timeline feature the two events matching this correlation (PANW and Elastic Defend).
- Review the process details like command_line, privileges, global relevance and reputation.
- Assess the destination.ip reputation and global relevance.
- Review the parent process execution details like command_line, global relevance and reputation.
- Examine all network connection details performed by the process during last 48h.
- Correlate the alert with other security events or logs to identify any patterns or additional indicators of compromise related to the same process or network activity.


### False positive analysis

- Trusted system or third party processes performing network activity that looks like beaconing.


### Response and remediation

- Immediately isolate the affected system from the network to prevent further unauthorized access or data exfiltration.
- Terminate the suspicious processes and all associated children and parents.
- Implement network-level controls to block traffic to the destination.ip.
- Conduct a thorough review of the system's configuration files to identify unauthorized changes.
- Reset credentials for any accounts associated with the source machine.
- Escalate the incident to the security operations center (SOC) or incident response team for further investigation and to determine if additional systems are affected.


## Rule Query

```eql
sequence by source.port, source.ip, destination.ip with maxspan=1m
 [network where event.module == "panw" and event.action == "c2_communication"]
 [network where event.module == "endpoint" and event.action in ("disconnect_received", "connection_attempted")]
```
