MITRE ATT&CK
T1059.005 Visual Basic for Applications T1059.001 PowerShell T1204.002 Malicious File

The sample is a Microsoft Word document containing VBA macros. The document body presents a quiz about 'The Odyssey' to trick the user into enabling macros. Upon enabling, the VBA macros execute a Shell() command, as indicated by the 'OLE_VBA_SHELL' heuristic. This suggests the document is designed to download and execute a second-stage payload. The 'macros.bas' file is identified as the source of these malicious macros.

Heuristics 5

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • ClamAV: Doc.Trojan.Marker-31 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-31
  • 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.
  • 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 macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code

Extracted artifacts 1
