A security analyst is investigating a suspected lateral movement event within a corporate network. XSIAM has generated a high-fidelity alert based on a behavioral indicator of compromise (BIOC) rule. The alert details indicate an unusual process spawning activity followed by a successful SMB connection to a domain controller from a non-privileged workstation. The current BIOC rule for 'Lateral Movement via SMB' triggers on 'Process.CommandLine contains 'net use' AND Network.Protocol == 'SMB' AND Network.DestinationAddress in 'DomainControllersGroup". This rule has a high false positive rate due to legitimate administrative activities. Which of the following modifications to the BIOC rule would most effectively reduce false positives while maintaining detection efficacy for malicious lateral movement attempts, considering the XSIAM context?
