Malicious Office (OOXML) / .DOC — malware analysis report

Heuristics 3

• CVE-2023-36884 — external RTF auto-load relationship critical CVE likely CVE_2023_36884
  Document auto-load relationship references a remote RTF file (https://mtss.bol-south.org/5974/1/8682/2/0/0/0/m/files-b2dff0ca/file.rtf), matching the stronger Storm-0978/RomCom external-RTF delivery shape. Plain clickable hyperlinks are not enough for this CVE rule.
• 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.
