MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The file is detected as malicious by ClamAV with the signature Doc.Downloader.Sload-6827538-0, indicating it belongs to the Sload family. A legacy WordBasic auto-exec macro marker (AutoOpen) was found, suggesting an attempt to execute malicious code upon opening. Although VBA macros could not be extracted, the presence of the auto-exec marker and the ClamAV detection strongly imply a downloader functionality.

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.
