Remediation Steps:
Immediately isolate the affected host from the network. Investigate process, network, and command-line logs to identify the C2 server, persistence mechanisms, and any lateral movement. Terminate the malicious process, remove the tool and its persistence, and rotate all credentials on the compromised system.
