MITRE ATT&CK

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

The file is an RTF document containing an OLE object, which is a common technique for embedding malicious content. The heuristic 'SE_ENABLE_LURE' indicates the document explicitly instructs the user to enable editing and macros, a typical social engineering tactic. The presence of an OLE object and the lure suggest the document is designed to execute embedded code or download a secondary payload upon user interaction.

Heuristics 3

\objupdate forces OLE activation high RTF_OBJUPDATE

RTF 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_OBJDATA

RTF contains 1 \objdata section(s) — embedded OLE objects
Macro/content-enable lure medium SE_ENABLE_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
