MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF file contains an embedded XFA form that exploits the CVE-2010-0188 vulnerability in Adobe Reader. This vulnerability allows for arbitrary code execution when the document is opened. The embedded file and JavaScript actions further indicate malicious intent, likely to download and execute a second-stage payload.
