T1204.002 Malicious File: Malicious File

This PDF file contains embedded JavaScript and a RichMedia (Flash) object, indicating an attempt to exploit vulnerabilities. The embedded JavaScript stream, named 'javascript_obj0017_000.js', likely contains malicious code designed to download and execute a secondary payload. The presence of `unescape()` and JavaScript actions further supports this conclusion. The file's primary purpose appears to be delivering and executing further malicious content.

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
