MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as a legacy WordBasic macro-virus by heuristics, and ClamAV specifically detects it as Win.Trojan.Angus-3. The extracted document body contains WordBasic code that appears to construct and execute a batch file named 'PCGURU4.BAT'. This suggests the macro's primary function is to drop and run a secondary payload.
