MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious Attachment T1559.002 Component Object Model Hijacking: Dynamic Link Library Search Order Hijacking

The PDF contains embedded JavaScript and RichMedia (Flash) content, indicating an attempt to exploit vulnerabilities. The embedded file 'sploit.swf' is highly suspicious and likely contains the exploit code. While a specific family cannot be determined, the presence of these elements strongly suggests a malicious intent to compromise the user's system.

Heuristics 5

RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
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
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
