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

The file is identified as malicious by ClamAV with the signature Doc.Trojan.Maldade-10036492-0. Static analysis revealed the presence of VBA macros within the OOXML document. The extracted VBA macro, though simple, indicates the potential for malicious code execution, likely to download and execute a second-stage payload. The document's structure and the presence of VBA macros strongly suggest it was delivered as a spearphishing attachment.
