MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT, PDF_JS, and PDF_EVAL. The presence of a launch action further suggests malicious intent. The embedded JavaScript file, 'javascript_obj0027_000.js', is suspicious and likely responsible for downloading and executing a secondary payload. The document body is unreadable, but the script execution and launch action point to a downloader or exploit delivery mechanism.

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.
