MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detection as 'Pdf.Exploit.Dropped-94' strongly suggests this JavaScript is used to exploit a vulnerability within the PDF reader. The large size of the embedded JavaScript object (45685 bytes) further supports the likelihood of it containing exploit code designed to download and execute a secondary payload. The document body content appears to be metadata and copyright information, offering no direct clues to the lure.
