Malicious Office (OOXML) — malware analysis report

Heuristics 4

• CVE-2023-36884 — external RTF auto-load relationship critical CVE likely CVE_2023_36884
  Document auto-load relationship references a remote RTF file (http://brep.cdn-edu.net/images/943D1884/45321/2195/9a9b6778/main.file.rtf), matching the stronger Storm-0978/RomCom external-RTF delivery shape. Plain clickable hyperlinks are not enough for this CVE rule.
• OOXML OLE2Link remote document — CVE-2017-8759 related high CVE related CVE_2017_8759_RELATED
  Document contains an o:OLEObject Type=Link whose external oleObject relationship fetches a remote Office-looking document. That is the OOXML OLE2Link staging shape used by CVE-2017-8759 campaigns when the remote document/WSDL supplies the SOAP moniker payload; the local file alone does not contain the WSDL body needed for an exact match.
• 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.
