MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits legacy WordBasic macro virus markers, specifically 'ToolsMacro', indicating the presence of malicious macros. ClamAV also detected it as 'Doc.Trojan.Wazzu-6'. While no specific IOCs like URLs or hashes were extracted, the presence of these markers strongly suggests an attempt to execute arbitrary code via macros, likely for malicious purposes.

Heuristics 2

  • ClamAV: Doc.Trojan.Wazzu-6 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Wazzu-6
  • 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.
