MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious Link

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics, and flagged as a suspicious extracted artifact. The ClamAV detection for 'Heuristics.PDF.ObfuscatedNameObject' further supports its malicious nature. The embedded JavaScript is likely responsible for downloading and executing a secondary payload, which is a common technique for malware delivery. The obfuscated nature of the JavaScript and the PDF content itself suggests an attempt to evade detection.
