Malicious Office (OOXML) — malware analysis report

Heuristics 6

• VBA project inside OOXML medium 3 related findings OOXML_VBA
  Document contains a VBA project — VBA macros present
• CreateObject call high OLE_VBA_CREATEOBJ
  CreateObject call
  Matched line in script

  Set objShell = CreateObject("Shell.Application")

• VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
  Triggers on the COMBINATION of two tokens co-occurring in the same compiled VBA/cache stream: an auto-execution entry point (Auto_Open / AutoOpen / Document_Open / Workbook_Open / Auto_Close / AutoClose) AND a shell/download/object-execution token (Shell, CreateObject, GetObject, PowerShell, cmd.exe, URLDownloadToFile, WinHttp, XMLHTTP, ADODB.Stream, ShellExecute, ExecuteExcel4Macro). Neither token alone fires it — it is the pairing that flags p-code-only or source-extraction-failure macro documents where the visible VBA source is unavailable. The matched tokens are named in the detail line below.
• AutoOpen macro low OLE_VBA_AUTOOPEN
  AutoOpen macro
  Matched line in script

  Sub AutoOpen()

• External hyperlinks (1) low OOXML_EXTERNAL_HYPERLINKS
  Document contains 1 external hyperlink — clickable URLs are stored as external relationships. First target: https://nationalinterest.org/blog/korea-watch/joe-bidens-north-korea-policy-will-put-allies-and-facts-first-167922
• 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.
