T1059.001 PowerShell T1204.002 Malicious File

This PDF document exploits several critical vulnerabilities including CVE-2009-4324, CVE-2009-0927, CVE-2007-5659, and CVE-2008-2992. These exploits are triggered by embedded JavaScript, which is obfuscated but ultimately designed to execute malicious code. The primary function appears to be the exploitation of PDF reader flaws to download and execute a secondary payload, as indicated by the ClamAV detection of Pdf.Exploit.Agent-36895.
