This hunt targets adversaries leveraging known 32-bit malicious web endpoints to deliver payloads or establish command-and-control channels within the organization’s network. Proactively hunting for these specific URLhaus indicators in Azure Sentinel is critical because it enables the rapid identification of legacy architecture compromises that may bypass standard perimeter defenses due to their reliance on older, widely exploited browser components.

Here are specific false positive scenarios for the URLhaus: 32-bit Malicious URLs detection rule, tailored for an enterprise environment:
Legacy Patch Management Scans
sccmagent.exe and ivantiagent.exe process names when accessing domains ending in .update.microsoft.com or specific Microsoft CDN subdomains (e.g., download.visualstudio.microsoft.com).Automated Software Deployment via Chocolatey
choco.exe service downloads 32-bit installer packages from vendor repositories (e.g., Adobe’s get.adobe.com or Oracle’s download.oracle.com) which are frequently tagged as “suspicious” by URLhaus due to high traffic volume and dynamic content.CHOCOLATEY-SVC) targeting known vendor domains such as get.adobe.com, download.oracle.com, and cdn.chocolatey.org.Database Reporting Services Connections
