MITRE ATT&CK
T1059.005 Visual Basic

The presence of legacy WordBasic macro virus markers, specifically 'ToolsMacro' and 'AutoOpen', strongly indicates the file contains malicious macros. ClamAV also detected it as Win.Trojan.Socks-1. The document body contains references to potential dropped files like C:\VIR4.DOC and C:\SOK.DOC, which are likely part of the malware's execution chain.

Heuristics 2

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