MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with multiple eval() calls, indicating obfuscation and likely malicious intent. The ClamAV detection 'Pdf.Exploit.Agent-36118' and the 'PDF_JAVASCRIPT' and 'PDF_EVAL' heuristic firings strongly suggest the exploitation of a PDF vulnerability to execute arbitrary code. The reconstructed JavaScript string points to the use of eval() to execute further code, typical of a downloader or dropper.

Heuristics 5
