MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious File

The RTF file contains embedded OLE objects, and the \objupdate heuristic indicates that these objects are configured to activate automatically. This suggests the file is designed to exploit OLE vulnerabilities or trick the user into activating embedded content, likely to download and execute a secondary payload. No specific family could be identified due to the lack of script content or clear indicators.
