MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers and the presence of 'BadBoy' and 'AutoOpen' subroutines. These elements suggest the file is designed to execute malicious code upon opening, likely through the AutoOpen macro, a common technique for macro-based malware. The document body's content, including references to 'BadBoy' and 'AutoOpen', reinforces this assessment.

    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.
