MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers within the document body and a heuristic firing for OLE_LEGACY_WORDBASIC_MACRO_VIRUS. While the document body contains standard text and file paths, the presence of these markers strongly suggests a malicious intent, likely related to the execution of legacy macro code. No specific family could be confidently identified.

Heuristics 2

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