MITRE ATT&CK
T1203 Exploitation for Client Execution

The file is a PDF identified as malicious by ML classifiers and ClamAV due to obfuscated objects and embedded content. The presence of an embedded file suggests it's designed to deliver a secondary payload. The XFA form structure is also noted, which can sometimes be leveraged for exploitation.
