MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with a high-confidence `eval()` call, indicating obfuscated code execution. ClamAV detection as 'Pdf.Exploit.Agent-36118' strongly suggests a known exploit. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, a common technique for malware delivery. The document body itself does not provide user-facing content, but the heuristics and ClamAV detection point to exploit-based execution.
