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

The OOXML document contains a VBA project with a Document_Open macro, indicating an attempt to automatically execute code when the document is opened. The presence of CreateObject calls further suggests the execution of potentially malicious functions. No specific malware family is identifiable from the provided heuristics and document body.

Heuristics 5

  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • VBA project inside OOXML medium OOXML_VBA
    Document contains vbaProject.bin — VBA macros present
  • 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.
