The sample exhibits characteristics of a legacy macro virus, specifically referencing 'RSN MACRO VIRUS Goat file' and containing WordBasic macro virus markers. The document body includes AutoOpen, AutoClose, and FileSaveAs subroutines, typical of older macro malware designed to execute automatically or upon specific user actions. The presence of these elements strongly suggests an attempt to deliver a malicious macro payload.
