MITRE ATT&CK

T1059.001 JavaScript

The PDF file contains embedded JavaScript, indicated by the 'PDF_JAVASCRIPT' and 'PDF_JS' heuristics. The 'CLAMAV_DETECTION' heuristic further flags it as malicious due to obfuscated objects. The embedded JavaScript stream is the primary mechanism for exploitation, likely to download and execute a secondary payload. The document body is heavily obfuscated and does not provide clear textual lures.
