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

The file is identified as malicious by ClamAV with the signature 'Doc.Trojan.Thus-8'. It contains VBA macros, specifically a 'Document_Open' macro, which is a common technique for executing malicious code upon opening a document. The document body suggests a lure, presenting itself as a confidential policy document that requires specific software versions, likely to trick the user into enabling macros. No scripts were extracted, and the embedded URL was confirmed benign, limiting further analysis of the payload.

Heuristics 5

  • ClamAV: Doc.Trojan.Thus-8 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Thus-8
  • ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV
    ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • 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.
