MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is an Excel spreadsheet containing VBA macros, with high-severity firings for OLE_VBA_MACROS, OLE_VBA_AUTO, and OLE_VBA_AUTOCLOSE. The auto_open macro attempts to run a command from a sheet named 'Niola', suggesting an attempt to execute arbitrary code. The presence of embedded URLs further supports the likelihood of this being a downloader. The ClamAV detection 'Doc.Downloader.Docusign112100-9908075-0' also indicates a downloader functionality.
