MITRE ATT&CK
T1059.005 Visual Basic

The sample contains legacy WordBasic macro virus markers and explicit text identifying it as a 'RSN MACRO VIRUS Goat file'. The document body contains numerous macro-related strings and instructions, suggesting the primary function is to infect the user's Normal template and potentially spread further. The ClamAV detection 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.
