MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, specifically identified as exploiting CVE-2007-5659 via the 'Collab.collectEmailInfo' method. This JavaScript is further deobfuscated into two files, 'legacy_pdfkit_stage_000.js' and 'legacy_pdfkit_stage_001.js'. The presence of these deobfuscated JavaScript streams and the ClamAV detection 'Pdf.Exploit.Agent-36065' strongly indicate that the PDF is designed to execute malicious code, likely for downloading and executing a secondary payload.
