T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The sample is an RTF document that contains OLE object data, which is automatically linked and updated. This indicates the document is designed to exploit OLE activation mechanisms to trigger embedded malicious content. While no specific script was extracted, the heuristic firings strongly suggest a malicious OLE object is embedded, likely intended to download and execute a secondary payload or lead the user to a phishing site. The document body is heavily obfuscated and unreadable, providing no further clues.
