MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects that are configured to automatically update and activate. This technique is commonly used to execute embedded code or launch external payloads upon opening the document. The heuristics indicate the presence of OLE object data and a native stream within the OLE object, suggesting the embedded content is intended to be executed. The specific attack pattern is likely related to social engineering to trick the user into opening the document, leading to the execution of malicious code.
Heuristics 4
-
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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
