Win.Malware.Noon-7057749-0 — Office (OOXML) malware analysis

Heuristics 6

• OOXML Ole10Native with payload/link indicators — possible CVE-2026-21514 high CVE likely CVE_2026_21514
  Office document contains embedded OLE (word/embeddings/oleObject1.bin) with Ole10Native plus executable, PE, or risky remote-link indicators. This is a likely CVE-2026-21514 exploitation shape.
• ClamAV: Win.Malware.Noon-7057749-0 critical CLAMAV_DETECTION
  ClamAV detected this file as malware: Win.Malware.Noon-7057749-0
• Ole10Native package drops an auto-executable payload critical OFFICE_PACKAGE_RISKY_FILE
  OLE Package displayName or fullPath ends in a directly auto-executable extension (a runnable binary or a script the default shell host runs on double-click). Embedding such a payload inside an Office document has no benign authoring use — it is a malware-delivery dropper.
• Embedded OLE object medium OOXML_OLE_OBJECT
  Document contains an embedded OLE object
• Payload URL recovered from embedded OLE object (10 URLs) info OOXML_EMBEDDED_OBJECT_URL
  An embedded OLE object (xl/word/ppt embeddings) carries a next-stage download URL in its Ole10Native/Package stream — stored literally (incl. UTF-16) or base64-encoded — which the package-level URL sweep does not see. Surfaced as an IOC; self-validating (only real payload hosts).
• 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.
