MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings related to PDF JavaScript actions and streams. The `unescape()` call and `ASCIIHexDecode` filter suggest obfuscation, a common technique for hiding malicious code. The extracted JavaScript file, `javascript_obj0006_000.js`, is likely responsible for executing the malicious payload.

Heuristics 5

unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits (matched inside decoded stream)
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
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.
