MITRE ATT&CK

T1059.001 Command and Scripting Interpreter: PowerShell T1204.002 Malicious File: User Execution: Malicious File

The PDF contains embedded JavaScript, flagged by multiple heuristics including PDF_JAVASCRIPT and PDF_JS. The ML classifier strongly indicates maliciousness. The JavaScript stream, identified as 'javascript_obj0001_000.js', likely contains obfuscated code designed to execute arbitrary commands, as suggested by the PDF_EVAL heuristic. The primary attack pattern involves luring the user to open the PDF, which then triggers the malicious script execution.

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.
