MITRE ATT&CK

T1059.005 Visual Basic

The file is identified as malicious by ClamAV with the signature Doc.Downloader.Powload-6790264-0. A legacy WordBasic auto-execution marker (AutoOpen) was detected, indicating an attempt to run embedded macro code. However, the VBA macros could not be extracted due to an unsupported Office format, limiting further analysis of the macro's specific actions.

Heuristics 4

ClamAV: Doc.Downloader.Powload-6790264-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Downloader.Powload-6790264-0
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

olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
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.
