MITRE ATT&CK
T1059.005 Visual Basic for Applications
T1566.001 Spearphishing Attachment
The sample contains a VBA macro that executes upon opening the document, as indicated by the Document_Open heuristic. The macro attempts to create a file named 'zoro.doc' in the user's template directory and opens it with a hardcoded password. The macro's functionality is partially obfuscated, but it appears to be designed to download and execute a secondary payload. The presence of the Document_Open macro and the attempt to create and open a new document strongly suggest a malicious intent to deliver further malware.
Heuristics 5
-
Office EPRINT stream contains EMF object high OLE_EPRINT_EMF_OBJECTOLE ObjectPool contains an EPRINT stream with EMF data. This is rare in normal documents and is CVE-2007-3893/MS07-046-family evidence when paired with Office exploit payload anomalies, but the malformed EMF record is not proven by this rule alone.
