MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript and an XFA form, triggering a critical heuristic for CVE-2010-0188, an Adobe Reader LibTIFF XFA image exploit. This indicates the document is designed to exploit a vulnerability in older versions of Adobe Reader to achieve code execution. An embedded file was also detected, suggesting a potential secondary payload.

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
