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

The file is a Microsoft Word document with a high-severity heuristic indicating the presence of VBA macros, specifically a Document_Open macro. ClamAV detections further confirm its malicious nature, identifying it as Doc.Trojan.Thus-8. The document body contains biographical information about a photographer, which appears to be a lure. No specific IOCs like URLs or hashes were extracted, and the VBA macro content was not detailed enough to reconstruct specific actions, leading to a moderate confidence level.

Heuristics 4

  • ClamAV: Doc.Trojan.Thus-8 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Thus-8
  • 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
