MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains an embedded XFA form that triggers a critical vulnerability, CVE-2010-0188, which is known to be used for arbitrary code execution. The exploit targets Adobe Reader's LibTIFF component. The presence of JavaScript actions and an embedded file further supports the malicious intent of delivering and executing a secondary payload.
