MITRE ATT&CK
T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF file contains an embedded OLE object that leverages the CVE-2017-11882 vulnerability in Equation Editor. This exploit is designed to execute arbitrary code, likely as a payload delivered via spearphishing. The extracted artifact 'objdata_00_off000001c7.bin' is a strong indicator of this exploit's presence.
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-2017-11882/0802 — suspicious Equation font record high CVE likely CVE_2017_11882RTF contains Equation Editor data with an anomalous MTEF font record shape. This is a static indicator for Equation Editor font-record overflow CVE families, stronger than CLSID presence.
