MITRE ATT&CK

T1204.002 Malicious File

The PDF file contains embedded JavaScript and a Flash object, both of which are commonly used to deliver exploits. The presence of `unescape()` and obfuscated JavaScript (`javascript_obj0017_000.js`) suggests an attempt to hide malicious code. The embedded `exploit.swf` file further indicates a likely exploit delivery mechanism. The overall pattern points to a malicious PDF designed to leverage these embedded components to execute further stages.

Heuristics 6

RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits
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
