MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF file contains an XFA form that triggers the CVE-2010-0188 vulnerability in Adobe Reader. This exploit is designed to allow arbitrary code execution upon opening the document. The embedded file and JavaScript actions further support the malicious intent, likely for delivering a secondary payload.
