MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy WordBasic macro virus, specifically triggering the 'ToolsMacro' marker. This indicates the presence of embedded macro code designed to execute automatically, likely for malicious purposes such as downloading further payloads or system compromise. The ClamAV detection as Win.Trojan.Trojan-19 further supports its malicious nature.

  • Legacy WordBasic macro-virus markers high OLE_LEGACY_WORDBASIC_MACRO_VIRUS
    OLE Word document contains legacy WordBasic auto-execution macro markers such as AutoOpen plus ToolsMacro/MacroFile/fileMacro/globMacro or named historical macro-virus strings. These old Word 6/95 macro forms are not exposed as a modern VBA project, so normal VBA source extraction can miss them.
