MITRE ATT&CK

T1559.002 Component Object Model Hijacking T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded Flash content (exploit.swf) and a JavaScript stream (javascript_obj0017_000.js). The JavaScript stream exhibits obfuscation and uses an eval() call, strongly suggesting it's designed to exploit a vulnerability, likely within the embedded Flash object. This combination points to a malicious document leveraging an exploit for Flash Player to deliver a payload.

Heuristics 6

RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
