What it detects
This rule detects msiexec.exe installing an MSI package from a remote WebDAV or HTTP location when launched by the WMI provider host, matching the LATRODECTUS loader delivery chain. The oversized JavaScript dropper uses WMI to spawn msiexec and retrieve a remote installer. This staging technique delivers second-stage payloads while evading direct download detection.
