Hunt Hypothesis

This hunt detects adversary behavior where attackers leverage known 32-bit malicious URLs to deliver payloads or redirect victims to phishing sites, often exploiting legacy systems that still rely on 32-bit architectures. A SOC team should proactively hunt for these indicators in Azure Sentinel because the high severity of these specific URLhaus entries suggests an active campaign targeting environments with mixed architecture, where 32-bit applications may lack modern security controls and are more susceptible to exploitation.
