MITRE ATT&CK
T1059.005 Visual Basic

The file is a Microsoft Word document containing VBA macros, specifically a Document_Open macro. This macro is likely intended to execute malicious code upon opening the document, as indicated by the critical ClamAV detection. No specific malware family could be identified, and the embedded URL was confirmed as benign.

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
