MITRE ATT&CK

T1059.001 PowerShell T1059.007 JavaScript

The PDF file contains XFA forms and embedded JavaScript, with high-confidence heuristics indicating JavaScript eval() calls and prototype pollution patterns. The embedded JavaScript streams are heavily obfuscated, but the presence of these indicators suggests the script is designed to download and execute a secondary payload. The PDF structure and the nature of the heuristics point towards a malicious document designed for exploitation or malware delivery.

Heuristics 8

Prototype-pollution JavaScript pattern high CVE related PDF_JS_PROTOTYPE_POLLUTION

PDF JavaScript mutates object prototypes while also referencing privileged or sensitive PDF APIs. This tracks a modern PDF exploit technique family without assigning an unverified CVE.
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution (matched inside decoded stream)
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
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. (matched inside decoded stream)
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. (matched inside decoded stream)
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
