MITRE ATT&CK

T1059.001 Command and Scripting Interpreter: PowerShell T1204.002 Malicious File Execution: Malicious JavaScript

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. A critical PDF_EVAL heuristic firing suggests the JavaScript is designed to execute arbitrary code, likely leveraging an exploit. The ClamAV detection 'Pdf.Exploit.Agent-13218' further confirms its malicious nature. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, a common technique for initial access.

Heuristics 5

ClamAV detected this file as malware: Pdf.Exploit.Agent-13218
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution (matched inside decoded stream)
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.
