T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample contains a VBA macro that is automatically executed upon opening the document, as indicated by the Document_Open heuristic. The macro uses CreateObject and GetObject calls, suggesting it's designed to interact with the system or download additional content. The obfuscated nature of the VBA code, combined with the detection of embedded URLs and the critical ClamAV alert, strongly suggests a malicious downloader. The primary IOC is the VBA macro file itself, which contains the malicious code.
