MITRE ATT&CK

T1059.001 JavaScript/JScript T1566.001 Spearphishing Attachment T1140 Deobfuscate/Decode Files or Information

The PDF file contains embedded and obfuscated JavaScript, as indicated by the PDF_JAVASCRIPT, PDF_JS, and PDF_UNESCAPE heuristics. ClamAV also flagged it as Heuristics.PDF.ObfuscatedNameObject. The embedded JavaScript file, 'javascript_obj0006_000.js', is highly suspicious and likely responsible for downloading and executing a second-stage payload. The obfuscation suggests an attempt to evade detection.

Heuristics 5

ClamAV: Heuristics.PDF.ObfuscatedNameObject critical CLAMAV_DETECTION

ClamAV detected this file as malware: Heuristics.PDF.ObfuscatedNameObject
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits (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
