MITRE ATT&CK
T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The sample is a malicious OOXML document that leverages an external OLE object, identified as related to CVE-2017-8759. This object points to a remote document at 'http://facextrade.com.br/wp-imcludes/4.doc', indicating an attempt to download and execute a secondary payload. The presence of multiple EMF objects is common in such exploits.
Heuristics 3
-
OOXML OLE2Link remote document — CVE-2017-8759 related high CVE_2017_8759_RELATEDDocument 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_OBJECTDocument 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_URLOne 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.URL http://facextrade.com.br/wp-imcludes/4.doc In document text (OOXML body / shared strings)
