MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious File

The PDF contains embedded JavaScript and a RichMedia (Flash) object, indicating an attempt to exploit vulnerabilities. The embedded JavaScript stream, named 'javascript_obj0017_000.js', contains obfuscated code with eval() calls, suggesting it's designed to download and execute a secondary payload. An embedded SWF file, 'exploit.swf', was also found, further supporting the exploit-based attack vector.

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
