MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File T1027 Obfuscated Files or Information

The RTF document contains embedded OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated, likely exploiting a vulnerability to execute code. While no specific payload or download URL was extracted, the presence of these heuristics strongly suggests an attempt to deliver a malicious payload. The document body is unreadable, providing no further context.
