T1105 Ingress Tool Transfer
The file is a malicious Excel spreadsheet containing VBA macros. The macros utilize the URLDownloadToFile API, indicating an intent to download a second-stage payload from one of the embedded URLs. The presence of Auto_Open and Auto_Close macros suggests automatic execution upon opening or closing the document. The ClamAV detection as 'Doc.Downloader.Docusign112100-9908075-0' further supports its role as a downloader.
