MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits legacy WordBasic macro virus markers, specifically 'fileMacro$', and contains explicit, albeit vulgar, messages about infection and spreading. The presence of these markers and the nature of the text strongly indicate a malicious macro designed to execute and potentially spread.

  • 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.
