MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript streams, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The JavaScript utilizes `eval()` and `String.fromCharCode` for obfuscation, suggesting an attempt to hide malicious functionality. The primary intent appears to be the execution of arbitrary code, likely to download and run a secondary payload. The presence of two large JavaScript streams and the use of obfuscation techniques point towards a downloader or dropper.

Heuristics 5

eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
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.
