The Document_Open VBA macro is designed to execute automatically when the document is opened. It constructs a batch file named 'god.bat' in the public documents directory. This batch file contains a PowerShell command to download a second-stage executable from 'http://coachcarmenwilliams.com/B86b0mDlYqpH2306105pdf.exe' and save it as 'databed.exe' in the same directory, before executing it. The macro then opens the created batch file, initiating the payload download and execution.

Heuristics 5

  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
  • 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.
  • 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.
