MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy WordBasic macro virus, specifically identified by the 'RSN MACRO VIRUS' marker and the presence of AutoOpen and ToolsMacro subroutines. The document body, while containing unusual text, reinforces the presence of these legacy markers. The primary technique observed is the use of Visual Basic for Applications (VBA) macros to execute malicious code.

  • ClamAV: Win.Trojan.Trash-11 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Trash-11
  • 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.
