MITRE ATT&CK
T1204.002 Malicious File: User Execution
T1566.001 Phishing: Spearphishing Attachment
The sample is an RTF document that exploits the CVE-2017-11882 Equation Editor vulnerability. The document body presents a fabricated financial audit report, instructing the user to 'Enable editing' to bypass security measures. This lure, combined with the known exploit, indicates a high likelihood of the document attempting to download and execute a secondary payload.
Heuristics 4
-
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.
-
\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 1 \objdata section(s) — embedded OLE objects
-
Macro/content-enable lure medium SE_ENABLE_LUREDocument instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
