MITRE ATT&CK
T1204.002 User Execution: Malicious File
T1027.001 Obfuscated Files or Information: Memory-only/RTF OLE
The sample is an RTF file containing embedded OLE objects (RTF_OBJDATA) and a directive to force OLE activation (RTF_OBJUPDATE). The presence of an Ole10Native stream with high entropy suggests an encrypted or obfuscated payload designed to be executed upon opening. The document body consists of randomized characters, which is typical of lures designed to bypass static analysis or hide the true nature of the document.
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
