MITRE ATT&CK
T1059.005 Visual Basic
The sample is a Microsoft Word document containing VBA macros, specifically triggering AutoOpen and Auto_Close functions. Heuristics indicate the presence of macros and an embedded artifact detected by ClamAV as 'Doc.Trojan.Aleja-1'. The document body is largely narrative and does not directly contribute to the attack pattern, but the presence of these macros strongly suggests an attempt to execute malicious code upon opening or closing the document.
