MITRE ATT&CK

T1059.001 JavaScript T1204.002 Malicious File

The critical ClamAV detection for 'Pdf.Exploit.Agent-36086' strongly indicates a known PDF exploit. Low-severity heuristics confirm the presence of embedded JavaScript, including the use of String.fromCharCode, which is often used for obfuscation. The embedded JavaScript stream, identified as 'javascript_obj0006_000.js', is the likely mechanism for delivering the exploit. The file's purpose is to leverage this exploit to execute arbitrary code, typically to download and run a second-stage payload.

Heuristics 5

ClamAV: Pdf.Exploit.Agent-36086 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36086
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. (matched inside decoded stream)
