MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The file is an RTF document containing an embedded OLE object, as indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated automatically, which is a common technique for exploiting vulnerabilities or delivering malicious payloads. The embedded artifact, objdata_00_off0000080f.bin, is likely the payload. No specific family could be identified, and no further IOCs were extracted.
Heuristics 3
-
\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.
