MITRE ATT&CK
T1059.005 Visual Basic for Applications T1204.002 Malicious File

The file is a malicious DOC document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The document body presents a financial report ('Metalnaft Sp.zo.o - Raport z badania sprawozdania finansowego za 2009r.') as a lure to encourage macro execution. The presence of the Document_Open macro indicates an attempt to automatically run malicious code upon opening the document, likely to download and execute a second-stage payload. One embedded URL was found with an unknown reputation.
