T1566.001 Spearphishing Attachment
The file is identified as malicious by ClamAV with the signature Doc.Downloader.EmotetExcel01220-9936774-0. Critical heuristics indicate the presence of Excel 4.0 macros, specifically an Auto_Open defined name, which is a common execution vector for Emotet. The macro sheet contains an Auto_Open entry, suggesting it is designed to run automatically when the workbook is opened. The document body content appears to be a lure for tracking blood pressure data, which is a common social engineering tactic.
