# Actionable Guidance for Arctic Wolf # Generated: 2026-03-23 11:00:45 # Step 1: Navigate to Arctic Wolf Unified Portal → Managed Risk → Vulnerabilities # Purpose: Identify any Quest KACE SMA appliances in your environment vulnerable to CVE-2025-32975 # Expected: A filtered list of internal or external assets running the vulnerable Quest KACE SMA software version, allowing you to prioritize immediate patching or isolation. # Step 2: Navigate to Arctic Wolf Unified Portal → Tickets → Create Ticket # Purpose: Engage your Concierge Security Team (CST) to initiate a targeted threat hunt for post-exploitation activity # Expected: A confirmed threat hunting ticket opened with the CST, specifically requesting them to leverage Arctic Wolf MDR to look for lateral movement, anomalous network traffic, or suspicious process execution originating from your KACE SMA IP addresses. # Step 3: Navigate to Arctic Wolf Unified Portal → Log Search # Purpose: Query network and endpoint logs for anomalous outbound connections or unauthorized authentication attempts originating from the KACE SMA appliance # Expected: Immediate visibility into any potential post-exploitation lateral movement, unusual administrative logins, or suspicious payload executions tied to the appliance. # Verification Steps: # - Review the CST threat hunt ticket updates in the Unified Portal # Expected: CST confirms no IoCs or lateral movement detected from KACE SMA appliances, or provides an immediate incident remediation plan if malicious activity is found # - Rescan the KACE SMA appliances via the Managed Risk scanner and check the Asset Details page # Expected: CVE-2025-32975 is marked as 'Resolved' and no longer appears under the active vulnerabilities for the Quest KACE assets
