MITRE ATT&CK

T1059.005 Visual Basic for Applications

The file is a Microsoft Word document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. ClamAV detections indicate it is a known trojan. The document body lists various project titles, likely a lure to trick the user into enabling macros. No specific scripts were extracted for further analysis, but the presence of the Document_Open macro and the ClamAV detections strongly suggest malicious intent.
