MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.007 JavaScript

The file is a PDF that leverages XFA forms and exploits CVE-2010-0188, a known vulnerability in Adobe Reader's LibTIFF component. The embedded JavaScript, although obfuscated, likely facilitates the execution of a second-stage payload. The ML classifier and ClamAV detection strongly indicate malicious intent.
