MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample is a PDF document that exploits CVE-2010-0188, a vulnerability in Adobe Reader's handling of XFA images. This exploit allows for arbitrary code execution. The PDF contains embedded JavaScript and an embedded file, suggesting a multi-stage attack. The embedded JavaScript is likely responsible for triggering the exploit and downloading/executing 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
