MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF document contains an embedded OLE object, identified as a package object, which in turn contains a PE header. This strongly suggests the document is a malicious container designed to deliver a Windows executable. The document body's text about a 'new insurance template' and a request to 'double click the icon' is a common social engineering lure to entice the user to execute the embedded payload.
