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

The file contains VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening the document. The document body presents a seemingly legitimate news article to trick the user into enabling macros. The presence of embedded URLs, though not directly used in the macro logic provided, suggests potential communication with external resources. The ClamAV detection as 'Doc.Trojan.Strings-1' further supports the malicious nature of the file.

Heuristics 5

  • ClamAV: Doc.Trojan.Strings-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Strings-1
  • 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.
