MITRE ATT&CK
T1059.005 Visual Basic for Applications T1547.001 Registry Run Keys / Startup Folder T1204.002 User Execution: Malicious File T1059.001 Command and Scripting Interpreter: PowerShell T1071.001 T1071.001 T1059.001 Command and Scripting Interpreter: PowerShell

The extracted VBA script contains a direct call to Shell() to execute a binary located at \\jdq\cc$\b.exe. Additionally, the script attempts to manipulate the VBA project of the Normal template (NormalTemplate.VBProject) to copy malicious code into the global template, ensuring persistence across other documents. It also disables virus protection settings and modifies the document's macro menu items to hide its presence.

Heuristics 7

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • ClamAV: Doc.Macro.DeleteMacro-6096859-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Macro.DeleteMacro-6096859-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
