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 PDF_LAUNCH heuristic suggests an attempt to execute an external action, and the PDF_EVAL heuristic points to the use of eval() for obfuscation. The extracted artifact 'javascript_obj0027_000.js' is suspicious due to script obfuscation indicators. The overall behavior suggests the PDF is a dropper designed to download and execute a secondary malicious payload.

Heuristics 5

Launch action high PDF_LAUNCH

PDF contains a /Launch action with an unresolved or extension-less target — treat as potentially dangerous
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.
