MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy macro virus, specifically identified by the 'RSN MACRO VIRUS' marker and the presence of WordBasic macro indicators. The document body contains embedded file paths and author information, likely intended to obfuscate the malicious nature of the file. While no specific second-stage payload or network communication was detected, the presence of these legacy indicators suggests a malicious intent to spread or infect.

Heuristics 2

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