MITRE ATT&CK

T1059.001 PowerShell T1027 Obfuscated Files or Information

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including 'PDF_JAVASCRIPT', 'PDF_JS', and 'PDF_EVAL'. The 'PDF_PAGE_WORD_XOR_EVAL_STAGER' heuristic suggests a stager mechanism. The embedded JavaScript file 'javascript_obj0010_000.js' is likely responsible for downloading and executing a second-stage payload, though its exact functionality is obscured. The presence of obfuscation indicators and eval calls points to a malicious intent to execute arbitrary code.

Heuristics 5

eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution (matched inside decoded stream)
Page-word XOR JavaScript eval stager high PDF_PAGE_WORD_XOR_EVAL_STAGER

PDF JavaScript enumerates rendered page words with getPageNthWord/getPageNumWords, extracts encoded byte fragments, XOR-decodes the stage with char-code helpers, and evals the result. This is an old exploit-kit staging pattern and is not normal document JavaScript.
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.
