T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The sample is an RTF document that contains an embedded OLE object, specifically targeting the Equation Editor vulnerability. The \objupdate directive indicates that the embedded object is intended to be activated automatically. This strongly suggests an exploit delivery mechanism, likely leading to the execution of a secondary payload. No specific family could be identified, but the exploit vector is clear.
