MITRE ATT&CK

T1059.005 Visual Basic for Applications T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature 'Doc.Trojan.Thus-8'. Static analysis detected VBA macros, specifically a 'Document_Open' macro, indicating an attempt to execute code upon opening the document. The document body contains academic text, likely a lure to encourage macro execution for downloading a second-stage payload.
