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

The file contains VBA macros, specifically a Document_Open macro, which is a strong indicator of malicious intent. The macro code appears to be designed to download and execute a second-stage payload, as suggested by the presence of embedded URLs and the overall structure of the VBA code. The ClamAV detections further confirm the malicious nature of the file. The document body itself discusses local community initiatives, which is likely a lure to disguise the malicious macro's true purpose.

Heuristics 4

  • ClamAV: Doc.Trojan.Marker-40 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-40
  • VBA macros detected medium 1 related finding OLE_VBA_MACROS
    Document contains VBA macro code
