MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious JavaScript

The PDF file contains embedded JavaScript that is heavily obfuscated and designed to exploit multiple Adobe Reader vulnerabilities. The heuristic firings and ClamAV detection strongly indicate that this is a malicious exploit delivery mechanism. The embedded JavaScript likely downloads and executes a second-stage payload, though the exact payload and destination are not discernible from the static analysis alone.
