T1204.002 Malicious File
T1566.001 Spearphishing Attachment
T1059.005 Visual Basic
The sample is a Microsoft Word document containing VBA macros, including AutoOpen and Auto_Close, which are commonly used to execute malicious code upon opening or closing the document. The document body contains DDEAUTO links pointing to an Excel file, suggesting a social engineering attempt to trick the user into opening a potentially malicious spreadsheet. The presence of VBA macros and the DDE execution vector strongly indicate a malicious intent to download and execute further payloads, as suggested by the ClamAV detection on an extracted artifact.
