MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The sample is an RTF document that leverages the Equation Editor vulnerability (CVE-2017-11882), indicated by the RTF_EQUATION_EDITOR heuristic. The RTF_OBJUPDATE heuristic suggests that the embedded OLE object is configured to automatically activate, leading to the exploitation of the vulnerability. The RTF_OBJDATA heuristic confirms the presence of embedded OLE object data. The primary attack vector is likely a malicious attachment delivered via spearphishing, leading to arbitrary code execution.
Heuristics 3
-
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.
-
OLE object data medium RTF_OBJDATARTF contains 2 \objdata section(s) — embedded OLE objects
