T1204.002 Malicious File
The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. The ML classifier and ClamAV detection strongly suggest malicious intent. The embedded JavaScript is likely responsible for downloading and executing a secondary payload, a common technique for initial access. While specific URLs were extracted, they are not directly indicative of malicious activity, and no specific family could be identified.
