T1566.001 Phishing: Spearphishing Attachment
The sample is a Microsoft Word document that exploits the CVE-2006-6456 vulnerability. This vulnerability allows for the execution of arbitrary code when a specially crafted malformed table SPRM is processed. The presence of an OLE ObjectPool disguised as an RTF file further indicates malicious intent. The document body contains heavily obfuscated and unreadable content, suggesting it is not intended for direct user interaction but rather to trigger the exploit.
