T1059.005 Visual Basic

The file exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers and ClamAV detection as Win.Trojan.Superstitious-1. The presence of 'AutoOpen' suggests an attempt to automatically execute malicious code upon opening the document. While no specific payload URLs or scripts were extracted, the file's structure and heuristic firings strongly indicate it functions as a downloader or initial execution vector for further malicious activity.
