MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits legacy WordBasic macro virus markers, specifically 'ToolsMacro', and is flagged by ClamAV as Win.Trojan.Paper-1. The presence of these indicators strongly suggests the file is a malicious document intended to execute embedded macros. The document body contains references to macro execution functions like AutoOpen, AutoExec, and ToolsMacro, further supporting this assessment.

    ClamAV detected this file as malware: Win.Trojan.Paper-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.
