T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF file contains embedded OLE object data and specifically triggers the CVE-2017-11882 vulnerability within the Equation Editor component. This exploit allows for arbitrary code execution, indicating a malicious intent to compromise the user's system. The presence of the ".bin" embedded artifact further supports the exploitation of this vulnerability.
Heuristics 5
-
Equation Editor CLSID critical CVE likely RTF_EQUATION_EDITOREquation Editor OLE CLSID found inside an OLE object — exploited by CVE-2017-11882 / CVE-2018-0802 / CVE-2018-0798
-
CVE-2017-11882 — Equation Editor FONT record overflow critical CVE likely CVE_2017_11882Equation Editor MTEF contains an overlong FONT typeface field, the vulnerable copy primitive for CVE-2017-11882. This is stronger evidence than the Equation Editor CLSID alone because it identifies the malformed record that drives code execution in EQNEDT32.EXE.
