MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The file contains a legacy WordBasic AutoOpen macro, a common indicator of malicious documents. The macro is heavily obfuscated, making it difficult to determine the exact payload, but the presence of the AutoOpen macro and the ClamAV detection strongly suggest it's designed to download and execute a second-stage payload. The obfuscated nature of the script and the lack of clear indicators for a specific family lead to a lower confidence score.

Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXECOLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
