T1204 Malicious File T1204.002 Malicious File: User Execution: Malicious Attachment

The PDF was flagged by multiple high-confidence heuristics, including ML classification and ClamAV detection, indicating it is a malicious document. The presence of an XFA form and an embedded script payload suggests an exploit is being delivered. The embedded script is likely responsible for executing the malicious payload, although its exact function cannot be determined due to obfuscation.
