Heuristics 4

  • OOXML OLE2Link remote loader — CVE-2017-0199 related high CVE related CVE_2017_0199_RELATED
    Document contains an o:OLEObject Type=Link whose external oleObject relationship points to a remote URL. This is the OOXML OLE2Link activation shape associated with CVE-2017-0199 delivery, but the local file does not expose URL Moniker bytes or a weaponized extension/content type, so the exact CVE cannot be proven statically.
  • ClamAV: Doc.Dropper.Agent-6495241-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Agent-6495241-0
  • External OLE object relationship high OOXML_EXTERNAL_OLE_OBJECT
    Document contains an oleObject relationship whose target is an external HTTP(S) URL. Office resolves this through OLE/object update paths rather than as a normal user-clicked hyperlink.
  • 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.
