MITRE ATT&CK

T1204 Malicious Link T1204.002 Malicious Link: Malicious File T1566 Phishing T1566.001 Phishing: Spearphishing Attachment

The sample is an RTF file containing an embedded OLE object, which is a known method for delivering malicious content. The document body provides a lure to enable editing, a common technique to bypass security measures and execute embedded payloads. The presence of OLE object data and the instruction to enable editing strongly suggest a dropper or exploit delivery mechanism.

Macro/content-enable lure medium SE_ENABLE_LURE
