MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, identified by the PDF_JAVASCRIPT and PDF_JS heuristics. Critical heuristics indicate the exploitation of CVE-2007-5659 using a method that concatenates info fields and evaluates the result. ClamAV also detected this as Pdf.Exploit.Agent-36062. The presence of deobfuscated JavaScript files suggests the script's purpose is to download and execute a second-stage payload, a common technique for initial access.
