MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF contains embedded JavaScript and uses ASCIIHexDecode and ASCII85Decode filters, which are commonly used to obfuscate malicious code within PDF files. These factors, combined with a high ML classifier score, indicate an attempt to exploit a vulnerability for client execution, likely involving JavaScript.
