Block 192.168.1.199: The image shows that the suspicious or malicious activity originated from this source IP address, making it a potential threat actor or compromised system on the network.
Blocking this IP helps prevent further communication or lateral movement from the suspected attacker.
Isolate the affected workstation: Since suspicious activities (like powershell_ise.exe running as an admin and launching splunkd.exe) are detected, isolating the workstation is a critical containment measure. This action disconnects the endpoint from the network, stopping any ongoing attack, lateral movement, or command-and-control activity, while allowing for forensic investigation.
"Isolating an endpoint and blocking the source IP address are best practices for immediate containment in the event of detected compromise or suspicious activity."

causality_actor_effective_usernamerecords the effective user after privilege changes, ensuring the query returns the actual user context that launched the process even when privilege escalation occurs.

A low EPSS score indicates a low probability that the vulnerability will be exploited in the wild, suggesting it is unlikely to be actively targeted despite having a high severity rating.

A manually assigned verdict locks the indicator's status; automated reputation updates (like the script result showing Malicious) do not override a manual verdict, so it remains Suspicious.
