MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample contains VBA macros, including AutoOpen and Auto_Close, which are commonly used to execute malicious code upon opening or closing a document. The 'ToolsMacro' subroutine attempts to disable macro security and prompts the user for a password, suggesting an attempt to bypass security measures and execute further payloads. The ClamAV detection as 'Doc.Trojan.Bablas-1' strongly indicates malicious intent.

Heuristics 5

  • ClamAV: Doc.Trojan.Bablas-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Bablas-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.
  • VBA macros detected medium 2 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • AutoOpen macro high OLE_VBA_AUTOOPEN
    AutoOpen macro
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
