This hunt detects adversaries leveraging known malicious URLs to deliver malware payloads, specifically targeting systems that have accessed the 37 identified threat indicators from URLhaus. Proactively hunting for this behavior in Azure Sentinel is critical because it enables the SOC team to identify early-stage compromise vectors and isolate affected endpoints before lateral movement or data exfiltration occurs.

Here are 5 specific false positive scenarios for the URLhaus: malware_download Malicious URLs detection rule, along with suggested filters and exclusions tailored for an enterprise environment:
Automated Patch Management Scans
https://urlhaus-api.abuse.ch endpoint directly, triggering a download event that matches the rule’s logic even though no actual user malware infection occurred.User-Agent string contains “SystemCenter” or “Ivanti”. Alternatively, filter out events where the destination port is 443 and the source process name matches ccmexec.exe.Endpoint Protection Cloud Updates
C:\Program Files\CrowdStrike\fs_qrdr.exe (or equivalent for SentinelOne/Defender) and the destination URL contains urlhaus.abuse.ch. This can be implemented via a rule filter checking ProcessName != "User Browser" AND DestinationURL LIKE '%urlhaus%'.Scheduled SIEM Data Ingestion Jobs
