MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file was detected by ClamAV as Doc.Downloader.Sload-6710134-0, indicating it functions as a downloader. Although VBA macros could not be extracted due to an unsupported format, the presence of an embedded URL and the ClamAV signature strongly suggest the document is designed to lure the user into downloading and executing a second-stage payload. The specific ClamAV detection name points towards the Sload malware family.

Heuristics 3

  • ClamAV: Doc.Downloader.Sload-6710134-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Sload-6710134-0
  • 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.
    URL http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
