MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The presence of an eval() call within the decoded JavaScript stream (PDF_EVAL) strongly suggests code execution. The ML classifier also flagged this PDF as malicious with high confidence. The embedded JavaScript file, javascript_obj0007_000.js, is the primary artifact, likely containing obfuscated code designed to download and execute a secondary payload.

Heuristics 4

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.
