MITRE ATT&CK
T1059.005 Visual Basic

The file is a malicious Office document containing VBA macros. The 'Document_Open' macro is present, indicating that malicious code will execute automatically when the document is opened. The presence of a large VBA macro (4273 bytes) and ClamAV detections further support its malicious nature. No specific family could be identified, and the embedded URL was confirmed benign.

Heuristics 5

  • ClamAV: Doc.Trojan.Marker-40 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-40
  • 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
