The sample leverages CVE-2023-36884 and OOXML external OLE object relationships to load an external RTF file from the URL https://www-communications-gov-pk.fetchdrive.org/17726/1/2573/2/32/0/0/m/files-f1f41bb3/Fontlayer.rtf. This indicates a likely attempt to download and execute a secondary payload. The document body discusses the formation of new provinces in Pakistan, likely a lure to disguise the malicious intent.

Heuristics 5

  • CVE-2023-36884 — external RTF auto-load relationship critical CVE likely CVE_2023_36884
    Document auto-load relationship references a remote RTF file (https://www-communications-gov-pk.fetchdrive.org/17726/1/2573/2/32/0/0/m/files-f1f41bb3/Fontlayer.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.
  • External relationship medium OOXML_EXTERNAL_REL
    External target in word/_rels\document.xml.rels: media/deer.jpg
  • 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.
