T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The sample is an RTF document that leverages OLE object data and automatic linking, as indicated by the RTF_OBJDATA, RTF_OBJAUTLINK, and RTF_OBJUPDATE heuristic firings. These indicate that the document is designed to automatically activate embedded OLE objects when opened, which is a common technique for delivering malicious payloads. The specific nature of the payload is not detailed in the provided evidence, but the mechanism strongly suggests a phishing or credential harvesting attempt.
