MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The file is detected as malicious by ClamAV as Doc.Downloader.Sload-6794075-0. A legacy WordBasic AutoOpen macro marker was found, indicating an attempt to automatically execute malicious code upon opening. Although VBA macros could not be extracted, the presence of the marker and the ClamAV detection strongly suggest a downloader or exploit payload. The document body content is obfuscated and does not provide clear user-facing text.

Heuristics 4

ClamAV: Doc.Downloader.Sload-6794075-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Downloader.Sload-6794075-0
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

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.
