MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Dropper.Agent-7217469-0' strongly suggests a dropper functionality. The embedded JavaScript file 'javascript_obj0009_000.js' is likely responsible for downloading and executing a secondary payload, a common tactic for droppers. The PDF_FROMCHARCODE heuristic further points to obfuscation techniques used within the script.

Heuristics 5

ClamAV: Pdf.Dropper.Agent-7217469-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Dropper.Agent-7217469-0
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)
