MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.005 Visual Basic T1140 Deobfuscate/Decode Files or Information

The sample contains VBA macros, including AutoOpen and Auto_Close, which are commonly used for malicious execution. The script explicitly disables macro security and exports a VBA component to 'c:\Windows.dat', indicating a downloader or droppper functionality. ClamAV detections for 'Win.Trojan.Pivis-2' and 'Doc.Trojan.Alamat-1' further support the malicious nature and suggest a known family.

Heuristics 6

  • ClamAV: Win.Trojan.Pivis-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Pivis-2
  • 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.
  • AutoOpen macro high OLE_VBA_AUTOOPEN
    AutoOpen macro
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
