T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample is identified as malicious by ClamAV with the signature 'Doc.Dropper.Agent-6399847-0', indicating it functions as a dropper. The presence of a 'Document_Open' VBA macro strongly suggests that the macro executes automatically when the document is opened, a common technique for initiating malicious actions. The macro's obfuscated nature and the heuristic firings point towards it downloading and executing a secondary payload, aligning with the dropper classification.
