MITRE ATT&CK

T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains embedded JavaScript, which is obfuscated using String.fromCharCode and eval() calls. This script is likely responsible for executing an exploit, as indicated by the ClamAV detection 'Pdf.Exploit.Dropped-94'. The extracted JavaScript file, 'javascript_obj0076_000.js', is a key artifact for further analysis.

Heuristics 6

ClamAV: Pdf.Exploit.Dropped-94 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-94
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.
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.
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
