MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The sample is an RTF document containing an embedded OLE object that leverages the Equation Editor vulnerability (RTF_EQUATION_EDITOR). The RTF_OBJUPDATE heuristic indicates that the object is designed to be activated automatically, triggering the exploit. The extracted artifact, objdata_00_off0000134b.bin, is likely the payload or a component thereof. The attack pattern suggests a malicious document designed to exploit a known vulnerability for initial execution.
Heuristics 4
-
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 1 \objdata section(s) — embedded OLE objects
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
