MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests it's an exploit. The embedded JavaScript is likely responsible for executing the exploit, potentially leading to the download or execution of a second-stage payload. The document body is heavily obfuscated and does not provide clear user-facing content, further supporting a malicious intent.
