MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. A high-confidence ML classifier also flagged the PDF as malicious. The presence of an eval() call within the decoded JavaScript stream suggests code execution, likely to download and execute a second-stage payload. No specific family could be identified, but the technique is common for initial compromise.

Machine Learning

Nyx PDF Classifier malicious score 1.0000

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.
