MITRE ATT&CK

T1059.001 PowerShell

The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detections (Win.Trojan.Agent-36166) confirm its malicious nature. The embedded JavaScript is likely responsible for executing malicious code or downloading further payloads, contributing to the overall attack. The file size and metadata suggest it's designed for exploitation.
