MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains an embedded XFA form that triggers the CVE-2010-0188 exploit, targeting a vulnerability in Adobe Reader's LibTIFF processing. This exploit allows for arbitrary code execution. The embedded file and JavaScript actions further support the malicious intent, likely to download and execute a 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
