T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1027 Obfuscated Files or Information
The RTF document contains embedded OLE objects, indicated by RTF_OBJDATA and RTF_OLE10NATIVE_STREAM heuristics. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be automatically activated upon opening the document. This mechanism is commonly used to download and execute a second-stage payload, although no specific download URL or payload hash was extracted from this sample. The truncated document body does not provide further context on the lure.
Heuristics 3
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
-
\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 2 \objdata section(s) — embedded OLE objects
