MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File

The file contains VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening. The document body presents itself as a press release with a link, likely intended to trick the user into interacting with the malicious content. The presence of VBA macros and the Document_Open heuristic strongly suggest an attack pattern involving macro-based execution. The ClamAV detection further confirms its malicious nature.

Heuristics 5

  • ClamAV: Doc.Trojan.Marker-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-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.
  • 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.
