MITRE ATT&CK

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

The RTF document contains OLE object data and uses an \objupdate directive, indicating an attempt to exploit embedded OLE objects. This is a common technique for delivering malicious payloads. While no specific script was extracted, the heuristics strongly suggest the file is designed to trigger an exploit, likely leading to the download and execution of a second-stage payload. The SHA256 hash is provided as a primary IOC.
