The PDF file contains embedded JavaScript and an embedded file, triggering heuristics for PDF JavaScript actions and embedded files. Crucially, it matches the CVE-2010-0188 exploit for Adobe Reader's LibTIFF XFA image handling, indicating an attempt to execute arbitrary code. The embedded file 'embedded_file_obj0004.bin' is likely the second-stage 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
AcroForm button with action trigger low PDF_ACROFORM_BUTTON

PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
