T1059.001 PowerShell T1204.001 Malicious Link T1204.002 Malicious File

The PDF file contains embedded JavaScript that exploits multiple known vulnerabilities including CVE-2009-0927, CVE-2007-5659, and CVE-2008-2992. The JavaScript is obfuscated and likely downloads and executes a second-stage payload. The ML classifier and ClamAV detection strongly indicate malicious intent.
