MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file was detected by ClamAV as Doc.Downloader.Emotet-6826542-0, indicating a downloader variant of the Emotet family. Although VBA macros could not be extracted due to an unsupported format, the presence of an embedded URL suggests a social engineering attempt. The URL http://schemas.openxmlformats.org/drawingml/2006/main, despite being labeled benign, is likely used as a lure within the document body to trick the user into clicking it, potentially leading to a secondary payload download.

Heuristics 3

  • ClamAV: Doc.Downloader.Emotet-6826542-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-6826542-0
  • Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED
    olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
  • 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.
