MITRE ATT&CK

T1059.005 Visual Basic

The presence of VBA macros, specifically a Document_Open macro, indicates an attempt to execute code upon opening the document. The embedded artifact 'macros.bas' and the ClamAV detection 'Doc.Trojan.Thus-10' further confirm malicious intent. The document body explicitly states 'This file contains a virus!', which is a common lure to trick users into enabling macros or proceeding with an infection.

Heuristics 3

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
