MITRE ATT&CK
T1204.002 Malicious File

The sample is an OOXML document identified as malicious due to the presence of an external OLE object relationship. This relationship points to 'https://www.hotelconchadomar.com.br/booking/13.doc', which is indicative of an attempt to exploit CVE-2017-8759. The document likely serves as a lure to download and execute a secondary malicious payload.

Heuristics 3

  • 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.
