MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.001 Malicious Link T1059.007 JavaScript/JScript

The PDF file contains embedded JavaScript that exploits multiple known Adobe Reader vulnerabilities including CVE-2009-4324, CVE-2009-0927, CVE-2007-5659, and CVE-2008-2992. The deobfuscated JavaScript stream indicates an attempt to execute malicious code, likely to download and run a second-stage payload. The ClamAV detection of Js.Exploit.HTML-28 further confirms its malicious nature.
