MITRE ATT&CK
T1566.002 Spearphishing Attachment
The sample is an RTF document containing embedded OLE object data, triggered by \objupdate directives. This indicates an attempt to execute embedded content, likely a malicious payload, upon opening. No specific family could be identified, and the document body was heavily obfuscated and unreadable.
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 1 \objdata section(s) — embedded OLE objects
