T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The sample is an RTF document containing embedded OLE object data, specifically triggering critical heuristics for Equation Editor exploitation (CVE-2017-11882). This indicates the file is designed to exploit a vulnerability in the Equation Editor component to achieve code execution. The presence of ` tf1 0 s24 0 s24 tlch bidis charset0 Times New Roman;` suggests it's a malformed RTF file, likely intended to be delivered via spearphishing.
