MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with the signature 'Doc.Trojan.Panther-2'. Static analysis detected VBA macros, specifically a 'Document_Open' macro, indicating a likely execution path for malicious code upon opening the document. The presence of VBA macros strongly suggests an attempt to download and execute a second-stage payload, a common tactic for malware delivery.
