The sample is a malicious OOXML document that leverages CVE-2023-36884 to load an external RTF object. This external object is hosted at the URL https://pubad-gov-lk.org-co.net/10472857/Profile.rtf. The document's structure and the identified CVE indicate a likely attempt to download and execute a secondary payload.

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 (https://pubad-gov-lk.org-co.net/10472857/Profile.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.
