Malware Insights

MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits legacy WordBasic macro virus markers, specifically 'fileMacro$' and 'autoOpen', indicating an attempt to execute malicious code upon opening. The presence of these markers and the ClamAV detection strongly suggest a malicious document designed to run embedded macros. The macro code appears to be attempting to move files and potentially execute further payloads, though the exact functionality is obfuscated.

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.
