MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers within its document body and a critical ClamAV detection for Win.Trojan.Cap-1. The embedded text suggests an attempt to disguise its malicious nature by including file paths and standard document elements, while the macro names like AutoOpen and FileSave indicate potential execution triggers.

Heuristics 2

  • ClamAV: Win.Trojan.Cap-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Cap-1
  • 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.
