T1204.002 Malicious File: Malicious File

This PDF file contains embedded JavaScript and exploits multiple known vulnerabilities including CVE-2009-4324, CVE-2009-0927, CVE-2007-5659, and CVE-2008-2992. These exploits target PDF reader components like media.newPlayer, Collab.getIcon, Collab.collectEmailInfo, and util.printf. The embedded JavaScript, particularly the deobfuscated version 'info_stride_js_000.js', is likely responsible for executing the malicious payload. The ClamAV detection 'Pdf.Exploit.Agent-36895' further confirms its malicious nature.
