MITRE ATT&CK
T1059.005 Visual Basic

The critical ClamAV heuristic indicates this file is a downloader, specifically identified as Doc.Downloader.Docusign0521-9864805-0. The presence of an embedded URL pointing to 'skyflyfares.com' further supports its role as a downloader. The XLM macro sheet suggests the execution of code to retrieve and likely execute a second-stage payload from the identified URL, impersonating a document delivery service.

Heuristics 3

  • ClamAV: Doc.Downloader.Docusign0521-9864805-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Docusign0521-9864805-0
  • Excel 4.0 (XLM) macro sheet present medium OLE_XLM_AUTOOPEN
    Workbook contains an Excel 4.0 macro sheet sub-stream — XLM is rarely seen in modern legitimate workbooks and was a major Office malware vector during 2020-2022.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
