MITRE ATT&CK
T1203 Exploitation for Client Execution

The RTF file contains an embedded OLE object that triggers a buffer overflow vulnerability in Microsoft Equation Editor (CVE-2017-11882). This vulnerability allows for the execution of arbitrary code, likely to download and run a secondary payload. No document body or scripts were extracted, limiting further analysis of the payload's intent.

Heuristics 3

  • CVE-2017-11882 — Equation Editor FONT record overflow critical CVE likely CVE_2017_11882
    Equation 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.
