T1204 Malicious Link
T1204.002 Malicious File
The file is an RTF document that contains an embedded OLE object, specifically targeting the Equation Editor vulnerability (CVE-2017-11882). This exploit is known to allow arbitrary code execution. The presence of ` tfobjdata` and ` tfobjupdate` directives further indicate the exploitation of OLE object handling. The ClamAV signature confirms the detection of this specific exploit. The likely intent is to download and execute a second-stage payload.
