T1204.002 Malicious File
This PDF was flagged by multiple high-severity heuristics and a machine learning classifier as malicious. It contains embedded JavaScript, which is often used to download and execute additional malicious content. The ClamAV detection name 'Pdf.Dropper.Agent-7293793-0' further supports its role as a dropper. The presence of JavaScript actions and streams, along with the unescape function, indicates an attempt to obfuscate malicious code execution.
