MITRE ATT&CK

T1059.005 Visual Basic

The sample contains a legacy WordBasic auto-exec macro marker ('Autoopen') and a high-severity heuristic firing indicating p-code auto-execution with shell execution tokens. Although VBA extraction failed, the presence of these markers strongly suggests an attempt to execute arbitrary commands upon opening the document. The specific command executed is not discernible due to the inability to extract VBA code.

Heuristics 4

VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXEC

OLE 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.
Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED

The Analyzer could not extract VBA macros: the document may be legacy, encrypted or malformed.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.

URL http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
