The presence of VBA macros, specifically an Auto_Close macro that utilizes Shell() and CreateObject calls, strongly indicates malicious intent. The ClamAV detection 'Doc.Dropper.Agent-8626163-0' further confirms this. The Auto_Close macro likely executes code to download and run a second-stage payload, a common dropper behavior.

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • ClamAV: Doc.Dropper.Agent-8626163-0 critical CLAMAV_DETECTION

  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
