MITRE ATT&CK

T1059.001 PowerShell

The PDF contains embedded JavaScript, indicated by the 'PDF_JAVASCRIPT' and 'PDF_JS' heuristic firings. The critical ClamAV detection 'Win.Trojan.Agent-36166' strongly suggests malicious intent. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload. The document body is heavily obfuscated and unreadable, providing no direct clues to the lure.
