The hypothesis is that the detected URLs are likely used by adversaries to deliver 32-bit malware, which may bypass modern endpoint protections. SOC teams should proactively hunt for these URLs in Azure Sentinel to identify and mitigate potential malware distribution channels before they cause widespread damage.
