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

The file is identified as malicious by ClamAV with the signature Doc.Dropper.Agent-6568107-0. The document body contains a lure to enable macros, and heuristics indicate the presence of VBA macros, although the actual code was removed. This suggests the file is a dropper designed to execute malicious code upon user interaction.

Heuristics 4

  • ClamAV: Doc.Dropper.Agent-6568107-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Agent-6568107-0
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • VBA project contains no executable statements low OLE_VBA_MACROS
    Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
  • 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)
