MITRE ATT&CK

T1203 Exploitation for Client Execution

This PDF file contains embedded JavaScript and an embedded file, and triggers a critical heuristic for CVE-2010-0188, an exploit targeting Adobe Reader's LibTIFF component via XFA forms. The presence of JavaScript and the specific exploit indicate the file is designed to achieve code execution upon opening. The embedded file and JavaScript likely facilitate the download and execution of a 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
