MITRE ATT&CK

T1059.001 PowerShell T1059.007 JavaScript

The PDF file contains embedded JavaScript, as indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The presence of a PDF_EVAL heuristic firing suggests that the JavaScript is obfuscated and uses eval() to execute arbitrary code. The ClamAV detection of 'Pdf.Exploit.Agent-36118' further confirms its malicious nature. The script likely downloads and executes a second-stage payload, a common technique for PDF-based exploits.

Heuristics 5

ClamAV detected this file as malware: Pdf.Exploit.Agent-36118
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
