MITRE ATT&CK

T1059.001 PowerShell T1059.007 JavaScript

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT, PDF_JS, and PDF_EVAL. The critical ClamAV detection of 'Pdf.Exploit.Agent-4035' strongly suggests an exploit is present. The document body contains obfuscated text that appears to be part of the script's logic, including references to 'eval()' and 'fromCharCode()', which are common in JavaScript exploitation techniques. The primary intent appears to be the execution of malicious JavaScript to exploit vulnerabilities within the PDF reader.

Heuristics 6

ClamAV: Pdf.Exploit.Agent-4035 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-4035
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.
String.fromCharCode low PDF_FROMCHARCODE

String.fromCharCode found — used to construct payload strings dynamically. Common in benign JavaScript libraries for codepoint manipulation, so this alone is informational; weaponised use is also caught by the dedicated fromCharCode-stage and exploit-shape rules.
