MITRE ATT&CK
T1059.005 Visual Basic
T1547.001 Registry Run Keys / Startup Folder
The sample contains a VBA macro that is triggered by the Document_Open event. This macro attempts to create a file named 'diplo.doc' in the user's template directory. The macro also attempts to modify registry keys related to VBA security settings, likely to bypass them. The presence of the Document_Open macro and the attempt to create a file in a user-specific directory suggest a malicious intent to execute further stages or establish persistence.
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.
