MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The file is an RTF document that contains an embedded OLE object, specifically targeting the Equation Editor vulnerability (CVE-2017-11882). This is a known method for exploiting systems to execute arbitrary code. The heuristic firings strongly indicate this exploit is present and active. No document body text was available for analysis, but the exploit itself is sufficient to infer the attack pattern.
Heuristics 5
-
Equation Editor CLSID critical RTF_EQUATION_EDITOREquation Editor OLE CLSID found inside an OLE object — exploited by CVE-2017-11882 / CVE-2018-0802 / CVE-2018-0798

-
\objupdate forces OLE activation high RTF_OBJUPDATERTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
-
