MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample is a malicious Office document containing a VBA macro with an AutoOpen subroutine. This macro attempts to execute a command using cmd.exe, likely to download and run a second-stage payload. The obfuscated command string suggests malicious intent, and the presence of an AutoOpen macro points to a spearphishing attachment delivery method.

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.
